The U.S. Environmental Protection Agency is charged by Congress with
protecting the Nation's land, air, and water systems.  Under a mandate of
national environmental lavs, the agency strives to formulate and Implement
actions leading to a compatible balance between human activities and the
ability of natural systems to support and nurture life.  The Clean Water
Act, the Safe Drinking Water Act, and the Toxic Substances Control Act are
three of (.he major congressional laws that provide the framework for
restoring and maintaining the Integrity of our Nation's water, for
preserving and enhancing the water we drink, and for protecting the
environment from toxic substances.  These laws direct the EPA to perform
research to define our environmental problems, measure the impacts, and
search for solutions.

     The Water Engineering Research Laboratory is that component of EPA's
Research and Development program concerned with preventing, treating, and
managing municipal and industrial waatewater discharges; establishing
practices to control and remove contaminants form drinking water and to
prevent its deterioration during storage and distribution; and assessing the
nature and controllability of releases of toxic substances to the air,
water, and land from manufacturing processes and subsequent product uses.
This publication is one of the products of that research and provides a
vital communication link between the researcher and the user community.

     This project was undertaken to identify and evaluate commercial paint
strippers with potential for reducing or eliminating sources of total toxic
organlcs (TTO) released from U.S. Army refurbishing facilities.  The
information gained from this research adds to our basic knowledge for
prevention or control of releases of toxic substances in wastewater
discharges.

                                   ABSTRACT


      A project was  undertaken to identify  commercial  paint  strippers  that
 would be less  hazardous  than MS-lll,  a stripper  containing  phenol  and up to
 85Z aethylene  chloride,  that is  used  at many military and industrial
 refurbishing facilities.  MS-lll  and  10 alternative commercial paint
 Ptrlpping formulations were  tested using a bench-scale simulation  of
 processing steps  used at  the Sacramento Army Depot (SAAO).  The
 effectiveness  of  each stripper was determined for immersion times  of  20 and
 35  minutes using  coupon samples of elflht different coating  systems cut form
 stock material provided by SAAD.   Relative toxicity and potential
 environmental  hazards associated  with each stripper were qualitatively
 evaluated to provide a ranking of  alternatives.

      Results indicated that  SAAD  should replace MS-111 wlch ENthone S-26
 diluted  In a 1:1  ration with water.   Since  the diluted S-26 contains  about
 25  Z  methylene chloride and  10Z phenol, total toxic organlcs loading  in the
 wastewater  from this source  can be decreased by as much as  60Z.  Further
 reduction can  probably be attained by greater dilution of S-26 stripper with
 water, but more tests are needed  to determine maximum dilution for effective
 stripping.

     This report was submitted In  fulfillment of Contract No.  68-03-3257 by
 Carltech Associates, Inc., under  the sponsorship of the U.S. Environmental
 Protection Agency.  This report covers the period May 15, 1985 to completion
of work on the  contract, January 31, 1986.

                                 INTRODUCTION
 BACKGROUND

     The  aaterlala  and equipment refurbishing activities  at military
 installations  throughout the country often result  in significant  pollution
 problems.   Removal  of  old paint, rust,  oil,  dirt,  or other surface coatings
 Is  nero.ssary to prepare the  surface for the  application of new protective
 coatings.   Removal  of  paint  from aluoinrjn is normally accomplished through
 use of organic solvents which often contain  toxic  compounds.  Because these
 organic solvents are  typically volatile and  partially soluble  In  water,
 problems  are often  encountered in the surrounding  work space and  in the
 wastevater treatment systems (7,8).

     One  of  the paint  stripping formulations used  extensively  at  military
 installations  Is MS-111,  a solvent containing phenol and  up to 8SZ methyiene
 chloride.   Because  of  its widespread use,  methylene  chloride is currently
 undergoing intensive study and investigation to determin
-------
chemicals Chan MS-lll.

     2.  Rank candidate substitutes for MS-lll in accordance with their
potential for pollution abatement and hazard reduction.

     3.  Conduct bench scale tests to provide data for comparative
evaluation of the stripping efficiency of the alternatives with that of MS-
lll.

     4.  Evaluate the potential for reducing operating hazards and the TTO
discharged to the wastewater treatment facilities at SAAO through the use of
Che most acceptable alternative stripper.

     It should be noted that this project was limited to the conduct of a
screening study of commercially available strippers used in accordance with
the recommendatlona of the manufacturer or supplier of che material.  No
provisions were made for extending the experiments Co cover Che
modification of commercially available strippers, or for the formulation of
new strippers.  Refinements in the formulation of effective strippers, and a
thorough evaluation of health and environmental effects, were beyond the
scope of work for this project.

-------
                                 SECTION 2

                                CONCLUSIONS
     MS-lll and ten alternative commercial paint atripping formulations were
tested in a bench scale setup simulating the processing steps uaed at the
Sacramento Arm/ Depot.  The effectiveness of each stripper was determined
for Immersion times of twenty and thirty five minutes using coupon samples
of eight different coating systems cut from utock material provided by SAAD.
The relative toxicity and potential environmental hazards associated with
each of the strippers was qualitatively evaluated to provide a ranking of
alternatives from most desirable to least desirable from a pollution
standpoint.  Based on analysis and evaluation of the data obtained, CARLTECH
has reached the following conclusions:

     1.  Of the commercial strippers tested, only strippers containing
methylene chloride, phenol, and an organic ac'd effectively removed the top
coat irem all eight paint samples using a subversion time of 20 minutes.

     2m  The TTO loading in the wastewater from the stripping operation at
SAAD can be lowered significantly by diluting a nethylene chloride/phenol
based stripper with water.  Of the commercial methylene chloride baaed
strippers tested only Enthone S-26 Is specifically formulated and
recommended by the manufacturer to be diluted with water.  This stripper
diluted in a 1:1 ratio with water effectively removed all types of paint
used in the screening tests.

     3.  Further reduction in the TTO loading In the waotewater at SAAD may
be attainable by greater dilution of methylene chloride based strippers with
water.  The minimum concentration of methylene chloride required for
effective stripping action has to be determined by testing.

     4.  N-methyl-2-pyrrolidone exhibited potential as a basic ingredient
In new stripper formulations for effective removal of paint from aluminum
components.  This conclusion is considered noteworthy since long term health
and environmental hazards have not been Identified in the limited data
available on this compcund.  Addltor^l testing is required, however, to
produce a completely effective Dripping formulation and to fully evaluate
health and environmental effects.

     5.  With the exception of epoxy based coatings, all ralnts tested can
be effectively removed with Oakite ALM heated to 82 C (1(*0°F).  Oakite ALH
contains no chemicals contributing to TTO in the vaatewater.

                              RECOMMENDATIONS
     Based on che analysis and evaluation of Che data obtained, and Che
conclusions cited above, it is recommended that:

     1.  The TTO loading in Che wastevater at SAAD be reduced in che near term
by using a diluted form of a mechylene chloride/phenol/acid based stripper.
A 50Z dilution with water Is recommended at this doe based on available
cesc daca.

     2.  Addiclonal bench scale testing be undertaken to determine che
maximum dilution of mechylene chloride/phenol/acid based strippers allowable
for effective stripping of the coatings encountered la che refurbishing
operation ac SAAD.

     3.  A limited development program be undertaken co determine che
feasibility of formulating an effective paint stripper baaed on n-mechyl-2-
pyrrolidone.

                                 METHODOLOGY


 INVESTIGATION OF MS-lll PAINT STRIPPER

      To establish a basis for evaluating alternative paint strippers, «
 study of MS-lll and its use In Che refurbishing process was necessary.
 Early IB the project, a meeting was held at Che Sacramento Army Depot
 (SAAO).  The scope of this project was reviewed with base personnel, the EPA
 Project Officer and a representative of the U.S. Anay Toxic and Hazardous
 Materials Agency (uSATHAMA).  The general requirements of the bench scale
 test program were established and It was agreed that SAAD would provide
 freshly painted panels to be used In the preparation of the paint sample
 coupons to be used in the test.  Following this meeting an Inspection of the
 refurbishing operations at SAAD was nude.  Special emphasis was placed on
 the details of the paint stripping process used at that facility.

      The objectives of this initial field Investigation were as follows:

      1.   To identify chemicals used in the cold stripping operation.

      2.   To document the operating techniques,  procedures and processes
 involved in the refurbishing of military equipment.

      3.   To assess the performance of  MS-lll  in relation to applicable
 military specifications  and the surface preparation  requirements for the
 next  step in the refurbishing  process.

      4.   To study the  equipment  and  processes use  relative to the potential
 for release of  toxic or  hazardous  materials to  the air  and wastewater
 effluents*

      5.   To determine  the  availability  of  items  typically  refurbished  at
 SAAD  for  use In  the  test program.

      6.  To identify the types of paint normally encountered  in  refurbishing
 operations  and to  ascertain which have  been found most  difficult to  remove.

      Following the field investigation, additional information on MS-lll was
obtained from the manufacturer and trade literature from the metals
finishing and associated industries.

-------
IDENTIFICATION OF ALTERNATIVE PAINT STRIPPERS

     Review of trade journals and ocher literature from the painting and
metals finishing Industrlet provided the Information necessary to develop a
list of the companies involved in the production and/or distribution of
commercial paint strippers.  Letters were sent to 68 companies requesting
information on commercial products suitable for removing paint from
aluminum, with a preference for strippers which did not contain methylene
chloride.  Materials safety data sheets (USDS), or other literature
describing the chemical composition of the stripper, were requested.  A list
of the most promising candidates was developed by reviewing information from
MSDS's (Appendix C), industry literature (7,8), general chemical references
(9,10), and electronic data bases (1.2,3).  Alternative strippers were
screened first with the objective of eliminating methylene chloride and any
other chemicals which contribute to TTO in wastewaters.  Since methylene
chloride was observed to be the basic chemical in most cold strippers, it
was later considered prudent to include strippers on the basis of reduced
methylene chloride content.

BENCH SCALE TEST PROGRAM

     The bench scale test  program was designed to simulate operating
conditions at the Sacramento Army Depot and  to provide performance data on
alternative strippers for  comparison with performance data on MS-111.  Test
procedures were prepared to obtain  the following types of data:

      1.  The efficiency of removal  of the paint finishes  typically
encountered in the SAAD refurbishing operation.

      2.  The effect of submei^ence  time on paint removal  efficiency.

      The personnel conducting  the  tests were also  Instructed  to  note  any
abnormal precautions  required  In  the handling of strippers, to  record weight
loss  data  on  the  coupons  tested,  and to provide detailed  comments on  the
results  of  a visual  inspection following  the stripping  and  steam lansing
operations  (Appendix  A).

      Each  stripping  formulation was tested at immersion times of 20 and 35
five  minutes  using  sample  coupons  from each  of the eight  different  coating
 systems  listed in Table  1.  Each set of  sample coupons  were stripped  for  the
 prescribed time,  neutralized in the caustic  bath,  rinsed  in the water bath,
and cleaned with a steam lance.  Following  the stripping  operation, coupons
Here dried,  weighed and  photographed to document  the results.  Photographs
were taken at both normal  size and at  7X magnification to allow closer
 inspection of the stripped surface. The normal size photographs, used to
 document comparative results obtained  for the eight coupons used in each
 test run,  were taken in color with a polaroid camera.  Although these
 pictures were useful in reviewing the results, no acceptable copies could be
 obtained for inclusion In this report.  Examination of the photographs taken
 at 7X magnification added little to the analysis of the f.est results.

-------
TEST EVALUATION PROCEDURES

     Performance of each candidate stripping compound was evaluated against
requirements of SAAD fnr surface preparation prior to application of new
coatings, and was compared to performance of MS-111 on similar paint samples
specifically prepared for the bench scale tests.  Test results were also
compared with operating results observed at SAAD.  Only strippers which
demonstrated capability to remove all types of paint provided as samples by
SAAD, were considered to be viable alternatives to MS-lll.  As a final step,
changes in stripping procedures or materials which might be required with
each viable alternative were assessed to identify any major impact on
processing rates and overall refurbishing costs at SAAD.

                           RESULTS AND DISCUSSION
ASSESSMENT OF THE MS-lll PAINT STRIPPER

Chemical Composition

     MS-lll, Che trade naie of an epoxy stripper produced by Miller-
Stephenaon Chemical Company, Inc., contains about eighty-five percent (by
volume) methylene chloride, ten percent phenol, five percent formic acid and
less than one percent surfactant.  The substance of greatest environmental
concern is methylene chloride, a highly toxic chemical normally found in the
vastewaters from metal refurbishing facilities.  Methylene chloride is a
major contributor to the Total Toxic Organics (TTO) found in the wastewaters
from the SAAD facility.  It enters the SAAD wastwater system principally
through "dragout", a term applied to material which adheres to metal parts
as they are removed from the stripping tank.  This material is deposited in
the rinse water, or renoved in the hot water/steam lancing operation and
discharged to the floor drain system.

     The phenol contained in MS-lll also contributes ro TTO in wastewaters.
However, the phenol concentration in the wastewater is much lower since it
is a minor component in MS-lll.  The manager of the stripping operation at
SAAD indicated that equivalent formulations manufactured by Buckley
Chemical and El Dorado Chemical, as well as pure methylene chloride, have
been used routinely ae make up for evaporation and "dragout" losses.
Consequently, the percentage of phenol in the stripping tank is expected to
be less than the ten percent listed in the formulation for MS-lll.

Industrial Utilization

     Mett/lene chloride based strippers are widely used in the metal
finishing industry.  Most acidic cold strippers have methylene chloride as a
major constituent in combination with other organic solvents.  Other
chlorinated oolvents, ketones and esters,  are sometimes used as substitutes
in strippers which do not contain methylene chloride (1).  The rarity of
commercially available cold strippers which do not contain methylene
chloride was confirmed during the course of this project (2).

Refurbishing Operations at SAAP

     The Sacramento Army Depot (SAAD) refurbishes communications and otoer
electronic equipment and the enclosures used to house the equipment.
Interior fixtures such as cabinets, drawers, brackets and other small metal

                                    8

-------
pares are removed froa the structure, stripped of their coatings, sand
blasted, electroplated, and repainted.  Fixtures fabricated froa steel are
normally cleaned and stripped of paint in a hot caustic bath.  However, the
major portion of the equipment encountered at SAAD is fabricated from
aluminum; exposure to hot caustic liquid would cause severe corrosion.
Aluminum is not generally attacked by cold acidic organic solvent-based
strippers; the stripping performance of MS-lll at SAAD has been quite
satisfactory.

     Disassembled cabinets and fixtures are loaded into a large wire mesh
basket and lowered into the cold strip (MS-lll) tank for approximately
twenty minutes.  The exact submergence time in the s(.ripper is left to the
operators judgement, since stripping efficiency is often affected by Che
shape of the pieces and the way they ara packed in the basket.  The floor
supervisor pointed out that use of an alternative stripper, which required a
significantly longer stripping time, would seriously affect their ability to
maintain normal throughput.  After a short drainage period the basket is
dipped briefly into a hot (77°C, 170 ?) caustic solution to neutralize the
acidity of the stripping solution.  After draining the caustic solution, the
basket Is submerged in a watar rinse tank.  Metal parts are individually
cleaned with a high pressure steam/hot water lance prior to transfsr to
the sandblasting operation.  A line diagram of the processing steps is shown
on Exhibit 1.

     This process was observed many times during the initial sice visit.
The coating is not removed completely by the chemical stripper, but merely
loosened to facilitate removal in the steam cleaning step.  Zinc chromate
primer used In some coating systems is not always removed by the cold
stripper.  This primer also remains essentially intact after steam cleaning
and requires sandblasting for removal.  There are no written specifications,
analytical procedures, or field tests available to measure the effectiveness
of the stripping operation.  The decision to pass the material on to sand
blasting is based solely on visual inspection by experienced personnel.
Stripping effectiveness is judged by the ease with which subsequent
processing steps, sandblasting, electroplating, and recoating, can be
successfully accomplished.

SELECTION OF SAMPLES FOR BENCH SCALE TESTING

     During the initial site visit to SAAD, base personnel discussed the
types of paint normally encountered in the stripping process*  Most
substrates were aluminum, although an occasional steel fitting was
encountered.  The most difficult top coats to remove are considered to be

Is not always removed in the stripping operation.  Aged coatings 'are
normally more difficult to remove than recently applied finishes.

     SAAD personnel did not believe it would be feasible to supply a
sufficient number of small fittings with the variety of coatings desired for
the testing of up to ten alternative strippers.  It was therefore agreed
that SAAD would prepare aluminum panels with the coatings of interest for

this study.  These panels were to be approximately 3 feet by 3 feet to
assure that sufficient stock material would be available for the preparation
of the test coupons required.  The SAAD staff also agreed to provide a
sufficient number of small pieces with aged coatings for proof testing of
the most promising strippers.

     The paint sample panels actually supplied for the bench scale tests
were reduced in size to approximately 1 foot by 1 foot for ease in shipping.
This necessitated a change in the test procedure to assure that sufficient
coupon* would be available for screening tests of all of the stripping
formulations selected.  The coupon size was reduced from 3 inches by 3
inches to  1 inch by 4 inches, and the three immersion times originally
specified, were reduced to two periods of 20 and 35 minutes.  The 10 minute
period was discarded since the normal dipping time at SAAD is 20 minutes,
and reducing the stripping time was not an objective of this study.
Additional sample panels were later provided for the preparation of back-up
test coupons, but were not required for completion of screening tests.  The
eight paint systems used In the screening test are identified in Table 1.

 IDENTIFICATION OF ALTERNATIVE PAINT STRIPPERS

      A wide variety of mechanical,  chemical,  and physical methods for the
 removal of paint are used in Industry.  Mechanical methods include sanding,
 blasting with abrasives, chipping,  and scraping.  Burning, immersion in hot
 aolten salt baths, and the use ot cryogenic temperatures are generally
 considered to be physical methods for paint removal. Most chemical paint
 removal technlqrea Involve the use of organic solvents or other chemicals
 designed to degrade the paint film structure or destroy adhesion of the film
 to the substrate.

                                     11

-------
      Chemical strippers are commonly classified as hoc or cold.  Hot
 strippers are usually highly alkaline and formulated on a base of caustic
 soda.  Most cold strippers are baaed on methylene chloride or similar
 organic solvents such as ketones and esters, and generally contain phenolica
 and aromatic hydrocarbons.  Cold strippers may be acidic, basic or neutral.
 Some are produced in emulsion form to facilitate removal with water.  Those
 containing phenols or cresols are usually acidic and can be rinsed with
 water.  Chemical stripping is accomplished via several different mechanisms.
 The paint can be dissolved to fom a solution with the sol;ent, or the paint
 film aay be destroyed by chemical reaction with the solvent.  In other cases
 penetration of the paint film, either directly or through scratches, holes.
 or broken edges, destroys its adhesion to the base material(7).

      While some hot acid strippers can be used safely, most hot caustic
 strippers cannot be used on aluminum because of the severe corrosion of the
 substrate.   Some modern finishes such as epoxies are designed to resist heat
 and alkaline attack .  Therefore, use of a cold organic solvent formulation
 is generally the most practical method for removing paint from aluminum
 surfaces.   These factors,  along with the objective of identifying a
 replacement for MS-lll  which could be used without extensive modification of
 the stripping process at SAAD,  helped to focus the search for alternatives.

 Contact with Potential  Suppliers

      During the month of June written requests for information on cold
 strippers and other products  which could be effectively used for removing
 paint frem  aluminum,  were  sent  to 68  companies.  This Initial Inquiry
 stressed our preference  for  strippers that did not contain methylene
 chloride or any equally  toxic organic solvent.   Only  three replies  had been
 received by the middle of  July.   Our  inquiry was later broadened to solicit
 information on any  formulation which  might be  considered  to  have less
 environmental  impact  than  MS-lll.   An intensive  campaign was  undertaken In
 which 48 of  the  companies  who had been sent  letters were again contacted  by
 telephone.   fhls produced  responses from an  additional  eight  companies.
 Although many  of the  strippers proposed  contain  some  methylebe chloride  six
 formulations were considered  to  have  potential for  reducing  the  TTO
 released.  As  the program  progressed,  three  new  strippers were identified
 for Inclusion  in the  screening tests, one  formulation was specified for
 testing in diluted form, and another was chosen  to be  tested  hot.  This
 brought the  total number of screening  tests specified to eleven,  including
 the base line  test of US-Ill.  Formulations  tested are shown in T..ble 2.

 BENCH SCALE TESTING

Test Specification And Protocol

     The specification set forth functional requirements for the bench scale
 test so that the equipment and procedures used would closely simulate the
actual conditions observed at SAAD's paint stripping facilities.  Based on
 thane functional requirements, detailed procedures were developed to assure
 that the sequence of events, time of submergence In each bath, and drainage
time allowed, could be followed precisely and duplicated for each stripper

  Summary Comparison of Alternative Strippers

       The  conclusions reached in this report  are based primarily on vlsral
  examination  of  the sample  coupons similar  to the procedure presently used  at
  SAAD.  Our analyses of stripping efficiency  for all of the formulations
  tested on the specially prepared paint sample coupons are summarized in
  Tables 3  and 4.  All strippers  containing methylene chloride are identified
  by the letters HC  after the  code number.  The percent removal  is indicated
  In TABLE  3.  for a  stripping  time of 20 minutes and in TABLE 4. for a
  stripping time of  35 minutes. In general, an increase in submergence time
  from  twenty  to thirty five minutes had little effect on the performance of
  the strippers.

      The first three strippers performed equally well on all of the paint
 systems tested.  Unfortunately,  the effective strippers contain methylene
 chloride, phenol, and an organic acid.  The fourth stripper, which was
 almost as effective as the first three, contains a high percentage of
 methylene chloride.  Stripper XI, which was Enthone S-26 diluted 1:1  with
 water, contained the smallest amount of methylene chloride (less than 25X
 based on the latest information received from the supplier).  Diluted S-26
 vaa as effective In removing all paints tested as MS-lll.   This conclusion
 was reinforced by results of subsequent testa using samples of  aged
 coatings.   Enthone S-26 diluted 1:1  with water,  MS-lll,  and Quick Strip Ho.
 8 were tested using small brackets  supplied by SAAD with an immersion time
 of 35  minutes.  The coatings on these brackets Included;  I) a water
 reducible  eposy primer,  2)  a water  base primer with an epoxy topcoat.  3)  a
 water  base primer with a chemical agent resistant coating  (CARC),  and  4)  a
 water  base primsr with an enamel topcoat.   All three strippers  effectively
 removed  100Z  of  the topcoat on  all samples.

     Observations by  the  personnel performing the  test  Indicated  that  both
 MS-lll and S-26  would  probably  have  been equally  effective with a  twenty
 minute immersion time.  Quick Strip  No. 8 appeared  to  require longer for
 complete removal of the aged paint samples, similar to the results  observed
 during the screening tests  on new paint samples.

 Assessment of Performance of  Candidate Strippers

     To obtain optimum performance, a cold organic  paint stripper must
 contain one or more solvents  capable of quickly penetrating the coating film
 to effect  a release of the  film  from the base material without  causing
 damage to  the substrate.  It  Is  not normally  desirable to completely
 dissolve the  film since the coating may be re-deposited as drying occurs.
 The stripper  may contain a  number of additional compounds to facilitate the
 operation of  the nain solvent, Increase versatility for removal  of  a variety
 of coatings,  accelerate the stripping action, conserve volatile solvents,
 and/or provide the  physical properties desired.  Thesa additives are
generally classified aa cosolvents, activators, corrosion inhibitors
evaporation retarders, thickeners, emulsiflers, or wetting agents.

     The strippers cesced In this project contained a variety of solvents
including aethyleue chloride, phenol, n-methyl-2-pyrrolidone, aethanol,
acetone, toluene, furfuryl alcohol, tributyl phospnate, butyl celloaolve,
diisobutyl ketone, and an unspecified cyclic amide.  In theory, the
effectiveness of methylene chloride la due to its small oolecular size which
facilitates rapid penetration of paint fllns, and to its Intermediate
solvency for various polymer coatings.  Swelling and lifting of the coating
from the substrate is preferred over complete dissolution in the solvent, to
avoid re-deposition problems.  As methylene chloride penetrates to the
substrate the film Bwe11s to several times its original volume.  The
swelling causes an increase in pressure at the Interface with the substrate,
and the resulting wrinkling and blistering causes release of the film from
the substrate.  Most of the stripper solvents cited above function in
essentially the same manner, although some do actually break down chemical
linkages, disrupt the continuity of the film, and partially dissolve the
polymer.  Methanol and phenol are often used as cosolvents to Increase the
volatility of the stripper in attacking coatings that resist the primary
solvent.

     The tera "activator" is applied to additives which increase the rate of
stripping.  Methanol and other polar solvents fit this description in some
applications.  Acids, alkalies, and amines are also used as activators.  The
activators encountered in the strippers used in this project Included formic
acid, hydrofluoric acid, dodecylbenzene sulfonlc acid, methanol, phenol, and
monoethanolamine.  The function of formic and other organic acids as
activators in the removal of epoxy coatings is relatively clear.  Organic
acids tend to hydrolyze ether linkages in the film and facilitate rapid
penetration by the solvent.  In the case of some of the stripper
formulations tested, it is not always clear as to whether the additive is
expected to function as an activator or a cosolvent.  In either cace they
are added to enhance and extend the performance of the primary solvent in
the stripper.

     The only evaporation retarder specifically noted in the formulations
was the paraffin wax used In Stripeeze.  This formulation contains acetone
and toluene which are significantly more volatile than many of the other
solvents encountered in this project.  Also, the use of a surface active
agent was only indicated in one formulation under the generic term
"surfactant".

     The exact formulation of chemicals used in paint strippers is often
considered to be a trsde secret.  The new laws governing the control and use
of toxic substances do require that the manufacturer identify all chemicals
1. a product that are proven health hazards if they constitute greater than
1Z of the product.  Carcinogens must be Identified at greater than 0.1Z.
This Information is contained in a Materials Safety Data Sheet (MSDS)
prepared by the manufacturer or distributor.  Even so, minor components
which are important in the performance of a stripper may be identified only
in general terms, or may not even be reported.  For example, the use of an
emulsifying agent was not indicated in the MSDS for the S-26 stripper
although it is obvious that some additive of this type is required to
facilitate dilution of methylene chloride with water.  Also, some of the

MSDS's available Co CARLTECU prior Co coopleClon of Chis project were
prepared before more strict regulations became effective la November 1985*
Within the limitations oa the accuracy and completeness of the chemical data
available, recognizing that the preparation of paint stripping
formulations is somewhat of an art, an attempt has been made to reconcile
the performance of the various strippers tested in this project from a
theoretical standpoint.

Miller Scephenson Chemical Company (MS-111)—
     MS-111 contains about 85Z merhylene chloride, 10Z phenol, 52 formic acid
and less than 1Z of a surfactant.  Mechylene chloride is the major solvent
In Che formulation and the mechanism of its attack, on paint films waa
discussed above.  1C is likely that phenol is used both as a cosolvent and
an activator to Increase che race of penecratlon of methylene chloride into
Che palnc film.  Specifically, the polyamides are soluble in phenol but not
in methylene chloride.  Phenol is also an organic acid that could be useful
in removing oxide films from the surface of the coating, thereby loosening
Che palnc film and improving che f «5tration of the methylene chloride.
Formic acid also helps In dissolving oxide films but Is probably used
primarily for its ability to hydrolyze ether linkages lu epoxy paints and as
a solvent for polyamides.  The surfactant simply assures chat the paint film
is thoroughly wetted with the stripping solution.

     The bench scale tests proved that this formulation is completely
effective in this removal of enamel (alkyd resin base with a variety of
pigments), epoxy, and polyamlde coatings in combination uith zinc chromate,
water reducible, and epoxy primers.  While methylene chloride is che major
constituent responsible for quick, loosening and release of the enamel
paint films from the substrate, it can be concluded that the penetration of
the epoxy and polyamide films is greatly affected by other constituents in
Che scrlpper.  Two other strippers, Stripeeze and Kutzlt, which contain
significant amounts of methylene chloride together with cosolvencs, were
ineffective in removing both epoxy and polyamide coatings within the 20
minutes allowed in the test.  The two missing ingredients were phenol and
formic acid, both of which are solvents for polyonldes.  Formic acid also
speeds the process by removing oxide films and breaking down the epoxies by
hydrolyzing ether linkages.

     MS-111 was completely effective In removing all of the aged coatings
used in the teat, including the Chemical Agent Resistant Coating (CARC),
which is based on an aliphatic polyurethane material.  Again, rapid
penetration of the solvent to the substrata with attendant swelling of the
film is considered Co be che primary mechanism for lifcing che polyurethane
film.

Enchone Inc. (S-26)—
     S-26 contains the same basic materials (methylene chloride, phenol, and
formic acid) as MS-111, and they are in approximately the same proportions.
The stripping mechanisms must therefore be similar for both strippers.  The
major differentiating characteristic of S-26 is its mlscibillty with water,
which allows dilution to reduce the percentage of methylene chloride In the
stripping bach.  A small amount of an emulsifying agent Is undoubtedly used

                                    18

-------
 in cho fornulaclon,  although 1C  la  not specified In the MSDS.   Emulsifying
 agentu can also enhance  the scrlpplag action by accelerating the  penetration
 of solvent into the  paint  film.

      Uith Che concentration of meChylene  chloride reduced,  a slower  stripping
 action night be expected.   However, S-26  diluted with an equal  volume  of
 water «2SZ mechylene  chloride)  provod to be completely effective
 for removal of all coatings at the  minlmua submergence time of  20 ml mi tea
 used in the test.  Diluted S-26  was also  as effective as MS-111 in Che
 removal of old paint films Including CARC (Appendix B).   This performance
 attests to the basic power of methylene chloride as a paint stripper when
 supplemented by suitable cosolvents and activators.

 Savogran Company (Stripeeze)—
      Stripeete contains  four solvents;  methylene chloride «20Z), methanol
 «30t),  toluene «40Z),  and acetone «25Z).   It is not obvious  that  any one
 of these would be considered as  the main  solvent in this formulation.
 Approximately 2Z parafin wax is  added as  an evaporation retarder, probably
 because of the relatively  higher volatility of  toluene and  acetone.  No
 acids  or other types of  activator are listed in the MSDS.

      Stripeeze was only  effective in removing some of  the enamel  coatings
 used in the test.  Even  Its effectiveness on enamel is apparently affected
 by the pigments used In  che paluc since only 70-80Z of che  white  enamel was
 removed.   The epoxy  and  polyaalde coatings were virtually untouched  even
 after  35 minutes submergence in  the stripper.

     Although mechylene  chloride is used  as  che basis  for many epoxy
 strippers,  acids are normally included  as activators Co  increase  che race  of
 stripping and co assist  in  breaking down  and penetrating the epoxy film.   It
 should also be noted that  none of the cosolvents  used  in Stripeeze are
 identified in che literature as  solvents  for polyamldes.  Bench teat results
 confirm the theoretically predicted performance in that  this stripper was
 useful only for removal  of  the enamels  among che  paint types tested.

 Savogran Company (Kutzit)—
     Kuczlt contains che same basic chemicals as  Stripeeze  roughly in equal
 proportions of  <30Z  for each of  che solvents.   As  in Stripeeze, about 2Z
 parafln wax was  added Co retard  eveporacion  of  che more  volatile solvents.
 Predictably,  che performance of  this  stripper was  similar to chac of
 Stripeeze.  Only enamels were removed in  che bench  teat  and  close to SOZ of
 Che Code  C  enamel remained on Che sample  coupon after  20 minutes submergence
 in che scrlpper.  The epoxy and  pniyamlde  coatings were  not  affected by this
 stripper.

 Oakite Produces. Inc. (ALM)—
     ALM  is  an  alkaline mixture  (pU-13) of furfuryl  alcohol  «10Z),
 trlbucyl  phosphate «5Z), monoethanolamlne (10Z), and sodium hydroxide (1Z).
 Furfuryl  nlcohol is  the major solvent in  Chis for "'atIon and trlbutyl
 phosphate  Is probably used as a  cosolvenc  based on its ability Co dissolve
vinyls and  nlcrocelluloslc materials.  Manoethanolamine  is a highly basic
compound used with sodium hydroxide  to produce  che high pB of the solution.

                                     19

-------
It may also be used as an emulsifler and softener.  The major stripping
actions expected would be solvent penetration of a limited variety of
coatings by furfuryl alcohol and tribi-tyl phosphate, and caustic breakdown
of an additional number of polymers when used at elevated temperatures.

     The results of the bench scale test were consistent with what theory
predicts.  At room temperature ALM was partially effective in removing the
enamels.  The epoxy and polyamfde coatings were unaffected.  At elevated
temperature the stripper was surprisingly effective in removing all of the
enamsls and the polyamides.  Even at the higher temperature, the epoxy
coating was essentially untouched.

     When ALM was used at ambient temperature, partial removal of the
enamels was probably accomplished through the solvent action of furfuryl
alcohol and tributyl phosphate.  At the elevated temperature, breakdown of
these paint films was accelerated by the caustic.  Failure of ALM to attack
the epoxy coating even at elevated temperature was probably due to the lack
of an effective solvent or organic acid in the stripper formulation.  Both
epoxy and polyamide are normally stable in aqueous caustic solutions.
Although softening and hydrolysis of polyamides are possible mechanisms for
the stripping action observed at the elevated temperature, it is likely that
attack of the amide bond by monoethanolamine was an important factor in the
performance of this stripper.

Oakite Products, Inc. (FUS)—
     FUS contains butyl cellosolve (35Z), diisobutyl ketone (10Z), and mixed
aromatic hydrocarbons (102) as cosolvents.  The formulation also includes
formic acid (15Z), dodecylbenzene sulfonic acid, and <5Z hydrofluoric acid.
On the basis of the variety of cosolvents and acids used in the formulation,
FHS was considered to have high potential for effective stripping of the
coatings used in the bench scale tests.  Unfortunately, this was not the
case.

     The test results were mixed in that all of the enamel coatings were
completely stripped and some of the polyamlde coatings were removed, but the
epoxy coatings were untouched.  It is concluded that the combination of
materials actually hindered the effectiveness of the formic acid as a
solvent for polyamides and that the other solvents present were ineffective
in lifting the epoxy film, even though acids were available to hydrolyze
ether linkages in that film.  The presence of strong acids, such as
hydrofluoric and dodecylbenzene sulfonic acid, would tend to retard
ionlzation of formic acid and thus interfere with ether cleavage.  This
stripper illustrates the degree of "art" involved in the formulation of
effective strippers.

Gaf Corporation (M-PYROL  114064)
     M-Pyrol is a trade name for n-methyl-2-pyrrolidone, an essentially pure
compound (99.5Z) used as  an industrial solvent and chemical reaction medium,
which has been proposed by the manufacture: for use in paint stripping
formulations.  Mo commercial paint strippers containing this chemical were
Identified during the conduct of this project.  M-Pyrol was selected for
testing in this project because it is not one of  the chemicals Included in

                                    20

-------
 the determination of TTO and the limited data available does not Indicate
 that It is a hazardous chemical.  It has proven capabilities as a solvent
 for a wide variety of polymers, including polyvinyls, polyaaldes,
 polyacrylics, cellulose derivatives, and fluorlnated hydrocarbons.  At least
 one patent has been Issued for paint strippers based on the use of M-Pyrol.

      The overall performance of M-Pyrol during che bench scale test
 was considered promising sin^e all of the enamel films and over 502 cf the
 epoxy coating were removed in the 35 minute stripping test.  Its performance
 on polyamides was disappointing since it is a proven solvent for this
 material.

      The only potential stripping mechanism for this chemical is solvent
 penetration of the paint film.  There was no acid to attack ether linkages
 in epoxy films, or other activators to speed the stripping action.  However,
 M-Pyrol was able to attack the epoxy coating.  Following the test it was
 learned that hot M-Pyrol has been shown to be effective in stripping
 polyamlde films.  This would be expected since the film softens at higher
 temperatures,  facilitating rapid penetration by the solvent.  The stripping
 action for all paint films is apparently greatly accelerated when M-Pyrol is
 used at 55-82  C (150-180°F), and the high boiling point (202°C,395°F) makes
 this operation feasible without excessive loss of the solvent.   Even partial
 removal of the epoxy coating during the test at room teoperature was
 considered significant since two of the strippers containing methylene
 chloride without an acid,  were completely Ineffective on this coating.

 Mitchell Bradford Chemical Company  (Quick Strip 08)—
     Quick Strip #8 contains methylene  chloride (60X) and an undisclosed
 acid.   Similar to MS-lll,  this  stripper combines  che solvent action of
 methylene chloride with an acid presumed to  have  the capacity for
 hydrolyzlng the ether linkages  in the epoxy  film  and for partial dissolution
 of  the  polyamides.

    ' This  formulation proved to be  an effective stripper for all of  the
 coatings  used  in the bench scale  test and was  also  effective In removing che
 polyurethane coating (CARC)  used  on one  of the aged paint  samples.   The
 stripping  action was not as  fast  as  that observed for MS-lll  and S-26.   This
may  have  been due to che absence  of  phenol in  the f omuls.

 Nalco Chemical  Company  (84TB-227)—
     The only information  available  for  the 84TB-227  stripper indicates  that
 It is composed  of approximately IOOZ of  an unidentified  cyclic  amide.  The
physical properties  listed on the data sheet are similar to n-methyl-2-
pyrrolidone, but  the  actually identity of the solvent could not be
confirmed.  Apparently  the distributor of this stripper did not feel
obligated  to specifically  identify che chemical used  because It has not been
designated  as a health hazard or carcinogen.

     The performance of 84TB-227 was similar to M-Pyrol in that nearly all
of the enamel coatings were removed  in the bench test.  There was no
degradation of  the epoxy or polyamlde coatings.  It is not possible to
speculate on the stripping mechanisms Involved without additional

infornatlon on the specific cbemical(e) contained In the foundation.

Analysis of Physical Data

     In addition to visual inspection, each of the saaple coupons was
neighed before and after the stripping operation.  The before and after
thickness of each coupon was also recorded (Appendix B).  Although these
data do not provide a precise measurement of stripping efficiency, they tend
to support the conclusions reached through visual inspection.  The average
weight and thickness losses noted for all samples which were Judged to be
completely stripped of topcoat were essentially the same,  analysis of
weight loss data also supports the assertion that Quick Strip No. 8,
although equally as effective as MS-1I1 and S-26, is a slower acting
stripper and could cause production delays if Implemented at SAAD.

     The amount of TTO discharged to  the wastewater can also be affected by
the viscosity or surface tension of the stripper.  Strippers which exhibit
poor drainage characteristics will increase the "dragout" from the strip

tank and,  therefore, the amount of stripper components which eventually find
their way  to the wastewater system.   During the bench scale tests, careful
measurements were  taken  to determine  the amount of stripping solution lost.
Oakite  ALM, when used hot, showed a marked increase in  -dragout".  There was
no detectable loss indicated for several of the non-oethylene chloride
strippers.  The losses measured for MS-lli, S-26(pure and diluted),  Quick
Strip 8,  and Stripeeze were roughly  the saae  (Appendix  B).

Effect  of  Overall  Characteristics of  Stripper Formulations

     Bpory paints  were kncvn  to be  resistant  to many organic  solvents.  This
belief  was confirmed by  results showing that  only strippers  containing
methylene chloride were  completely effective  in  reaoving this coating.
 However, the strong resistance of  the polysmide  coatings to many of  the
 strippers tested  was not expected.   The results  were even more surprising
 since two of the  Ineffective strippers contained significant quantities of
methylene chloride.  Closer examination of the stripper formulations
 indicates that pU may have been the determining  factor.   All of the
 Ineffective strippers had a neutral pH.  ALM, an alkaline stripper,  removed
 100Z of the polyamlde topcoat in twenty ainutes  when heatrd to 82 C (180 ),
 and the weight loss data was roughly equivalent to that obtained using MS-
 111.  Acidic strippers were judged to be 100Z effective in reaoving
 polyamlde topcoats.  Since ALK was not effective when used at ambient
 temperature, the temperature effect was probably more important than  the
 alkaline pH.

 Effect of Temperature on  Stripper Performance

      Oakite ALM was the only stripper initially recommended for use  at an
 elevated  temperature by the supplier.  Its performance drastically improved
 for the removal of both enamel and polyamlde top coats.  Subsequent  to
 completion of the  test program the supplier of n-methyl-2-pyrrolldone (M-
 Pyrol) also recommended raising the  temperature of this stripper to  improve

                                      22

                      TEST SPECIFICATIONS AND PROTOCOL
INTRODUCTION

Background

     The refurbishing of materials and equipment at various military
installations throughout the country is an activity that often contributes
significantly to pollution control problems*  Prior to the application of
new surface finishes, all rust, oil, dirt, and old paint must be removed.
In the case of equipment fabricated from aluminum, this is normally
accomplished through the use of organic solvents, most of which contain
compounds that are highly toxic.  One of the most effective paint stripping
compounds currently in use for this application is MS-111, a solvent
containing about IOZ phenols and up to 85X methylene chloride.  This paint
stripper contributes to the total toxic organic (TTO) loading in the waste
waters discharged from the facility, creates potential air pollution
problems, and leads to the possible formation of toxic or hazardous waste
sludges in waste water treabceac systems.

     A number of commercial paint stripping fcirculations have been
identified that contain chemicals that may be environmentally more
acceptable than those contained in MS-111.  While these formulations are
considered to have the potential of performing the stripping operation as
well as MS-111, data from systematic, controlled testing under comparable
conditions is required to determine the true acceptability of these
alternatives.

Objectives

The objectives of this test specification are to provide the bases for:

     1.   The development of the detailed test procedures to obtain the data
necessary to fully evaluate and compare the performance of up to ten (10)
alternative paint stripping formulations with that of MS-111 under carefully
controlled conditions that are similar to those encountered in the equipment
refurbishing activities at the Sacramento Army Depot (SAAD).

     2.   The design of equipment to carry out these bench scale testing
procedures for the various alternative paint stripping formulations.

     3.   The development of a complete cost proposal for the procurement of
all required equipment and materials, and performance of the prescribed
testing*

     In addition to visual inspection of test pieces following the stripping
operation, the proposer should recommend any surface testing or other means
which might prove useful in evaluating the effectiveness of the individual
stripping formulations.  As a minimum the sample coupons should be examined
and photographed at 10X magnification.

Design of Test Apparatus

     Except as noted below the proposer is to provide all equipment and
materials necessary to carry out the bench scale test program.  Tanks and
other equipment used for the cold stripping and hot caustic baths must be
constructed of materials suitable for the handling of these hazardous
liquids.  The test apparatus must be installed so that adequate ventilation
is provided for the protection of the personnel conducting the tests.

The following material will be provided by CARLTECH:

     1.   Sheet aluminum panels (approximately 3'x3') .coated In accordance
with varioiid military paint specifications.  These panels will serve as
stock material for the preparation of coupon samples.

     2.   The paint specifications for each aluminum panel provided above.

     3.   A complete list (maximum of ten) of all commercial paint stripping
formulations to be used in the bench scale tests.

     4.   Material Safety Data Sheets and/or the complete chemical
formulation of all candidate paint strippers.

     5.   An adequate supply of aluminum components with 'aged' coatings for
final testing of the most promising strippers.

The contractor shall provide for the folLowing:

     1.   The design and fabrication or procurement of all required tanks,
vessels and materials handling equipment.

     2.   The design and preparation of all required coupon samples.

     3.   The design and fabrication of sample holders for submersion of
samples in the process tanks.

     4.   The provision of equipment and/or Instrumentation proposed for

Utility Requirmeots

     la order to conduct the bench scale testing in a safe and effective
Banner, the contractor's facility muat provide:

     1.   Ventilation equipment adequate to handle any noxions fines or
vapors that may evolve froa the organic stripping baths and caustic wash.

     2.   A steam/hot vater Lance supplied  with saturated steaa or hot
water at a temperature of at least 220 degrees Fahrenheit.

     3.   Steaa or electric heating capacity  to maintain the caustic bath ac
a temperature of approximately 180 degrees Fahrenheit.

     4.   A satisfactory system for handling  spills  and accidental
discharges.

     5.   Adequate protective clothing and safety equipment for personnel
performing the test.

Analytical Requlrmenta

     Although a major objective of  this  program Is  to  identify an  acceptable
cold stripper for aluminum  that will  reduce  tne environmental  hazards
involved  in  the operation,  it  is  unlikely that any  meaningful  quantitative
information  on potential pollution levels can be obtained  from the bench
scale  teats.  Therefore, no requirement  for  analysis of  the stripping  baths
or  rinse  waters from the process  is anticipated.  However, proposers should
provide a complete  description of their  analytical  capabilities  as an  aid  in
evaluating the flexibility  available  to  meet changing  requirements that may
develop during the  testing.

Reporting Requirements

      1.   Weekly  progress  reports should be  sent  to CARLTECH.   The report
          should  be brief  and provide a concise description of the status  ol
          the  test  program along with a statement of the work scheduled for
           the  following week.   The contractor may use any format considered
          appropriate.

      2.   A final technical report will be  submitted within ten (10) working
          days following  the completion of  all testing.  This report will
           contain an evaluation of the performance  of  all stripping
           formulations used in the test program,  a  ranking of all strippers
           from the most effective to the least effective, normal size  and
          magnified photographic documentation of  the surface condition of all
           sample coupons  used in the test and data obtained from any

                                     30

          additional testing of  sasple surface conditions that may be proposed
          by the contractor and  approved for use In the test program by
          CARLTECH.

     3.   The contractor must agree to provide acc-.ss to CARLTECH employees
          and other concerned parties as designated by CARLTECH for
          observation of the stripping tests and at other reasonable tines
          during noraal working hours as mutually agreed for discussions to
          resolve any problems that may arise during the test program.

QUALITY ASSURANCE

     It Is the policy of CARLTECH to produce engineering and scientific
studies of the highest caliber.  In keeping with the corporate goal of
excellence the management of CARLTECH has made a commitment to the quality
assurance goals of  the Envlronnental Protection Agency.  All reported data
will be accompanied by calculations of precision and accuracy, and
Information on completeness, representativeness and comparability will be
supplied as appropriate.

                                  APPENDIX D

                      TOXICITY DATA - STRIPPER CHEMICALS


 84TB-227 — NALCO CHEMICAL COMPANY

      The identities of Che ingredients of this stripper have not been
 revealed.  Manufacturer claims that it is "a cyclic amide."  There is no
 Threshold Limit Value (TLV) established for this product according to the
 manufacturer's Material Safety Data Sheet (MSDS) (I).  It is an eye and skin
 irritant.  The MSDS also claims it is not regulated under RCRA.    The
 Advance Technical Data Sheet from Nalco claims there are no heavy metals or
 EPA regulated solvents (2).

  M-PYROL 1140641 — GAP CORPORATION

      This is not a formulation, but a 99.5Z pure liquid form of N-methyl-
 pyrrolidone.  CAP, in their Summary of Toxlclty Information report (3) that
 it Is mildly to moderately toxic by ingestion and is a skin irritant.   Acute
 dermal toxlcity tests have shown that is not in the range ordinarily
 classified as toxic by this route under the Federal Hazardous Substances
 Act.   It is an eye irritant but permanent eye damage has not occurred  In
 tests.  It is not a mutagen as measured by  the Ames Test (3).  In 1976,  the
 intraperitoneal administration of N-methylpyrrolldone showed teratogenlc
 effects  (4).   Subsequent  studies conducted  in 1982, using the dermal route
 of application showed no  teratogenic effects or effects on the dams at 75
 mg/kg and 237 mg/kg of body weight in Sprague-Dawley rats(S).   An EPA
 evaluation tentatively assigns a conservative 25 mg/kg as the no-effect
 level.   CAP,  using the Warburg respirometry technique,  have demonstrated
 that  M-Pyrol  is biodegraded by raw sewage bacteria, according to  CAP Product
 Information Sheets (3).

 S-26  —  ENTHONE,  INC.

      S-26 has  the  some major constituents as  MS-HI.   However,  the
 concentration of methylene  chloride  is  greatly  reduced.   Methylene chloride
 is 50Z;  phenol  is  20*  and formic  acid  is  5Z.  This  stripper  is  formulated to
 be mlseible with water, forming a clear fluid at  1:1 dilution.  This
 property of the stripper was designed  into  the  formulation.  The
manufacturer  recommends a 1:6 dilution  with water and claims  the  formulation
works In a range from  1:4 to 1:20 dilutions (6).  See MS-111 for more
 Information.
                                    102

-------
STRXPEEZB — SAVOCRAN COMPANY

    Stripeeze contains a reduced amount of methylene chloride, only 20Z.
See MS-111 for additional Information.  It contains less than 40Z toluene
according to the MSDS.  Toluene Is included In the determination of TTO
(Total Toxic Organice) under 40 CFR 413 (7).  It Is currently listed in the
Registry of Toxic Effects of Chemical Substances (RTECS) to be a outagen,
tunorigen, ceratogen and skin and eye Irritant.  However, RTECS has not been
peer-reviewed.  Toluene is currently under test through tha National
Toxicology Program Carcinogenesis Study.  The ACGIH (American Conference of
Government Industrial Uyglenists) recommends a TWA of 100 ppm.  OSUA
currently has set 200 ppm for TWA.  Stripeeze contains less than 30Z
methanol.  OHMTADS reports that It will blodegrade vny rapidly.  There is
no direct evidence that It is a carcinogen, but it is highly toxic when
ingested.  Human oral LOLo is 340 mg/kg as reported by RTECS.  RTECS also
lists mutagen and ceratogen data.  The OSUA Standard  is 200 ppm TWA (9).

     Stripr.eze contains less than 25Z acetone.  It is an irritant,
especially bronchial, however OSUA  has currently set the TWA at 1000 ppu.
There is one study in RTECS that reports  teratogenic data.  The outagenlc
level is very high, one study reports 40  grams per liter (9).

KUTZIT — SAVOCRAN COMPANY

     Kutzlt has  the same constituents as  Stripeeze (above), except  that  the
percentage composition is slightly different.  The MSDS lists methylene
chloride, toluene, methanol, and acetone  as all being under 30Z and paraffin
wax  as less than 2Z.  See discussion  above.

QUICK STRIP « — MITCHELL BRADFORD CHEMICAL COMPANY

     Quick Strip *8 contains 60Z methylene chloride and an undisclosed  acid.
See  discussion under MS-111 for methylene chloride.

MS-111 — MILLER-STEPHENSON CHEMICAL  COMPANY

     MS-111 contains  8SZ methylene  chloride,  10Z  phenol, 5Z formic acid and
a surfactant,  «Z1).  Methylene  chloride  and phenol are both  Included  in the
determination  of TTO  (7).  OHMTADS  (Oil and Hazardous Materials Technical
Assistance Data Service)  reports  that methylene chloride is probably not
biodegradable,  but that  Ippm solutions  of phenol  are  (8).   Methylene
chloride is currently under  study  by EPA  under TSCA to  determine  if
methylene chloride poses  an  unreasonable  risk  of  cancer,(10)  nnd  under the
Clean Air Act  to determine if  it  should be  added  to the list  of hazardous
air  pollutants (11).  RTECS  lists methylene  chloride  as  a  tumorlgen,
mutagen, teratogen and  skin  and  eye Irritant.  The current OSHA standard is
500  ppm TWA,  but 75 ppm has  been recommended by  the ACGIH  (9).  MSDS's
submitted by the various manufacturers  recommend  200-250 ppm  TWA.

      Phenol  is also considered a tumorlgen,  mutagen,  teratogen, and skin acd
eye  irritant by RTECS.   Phenol hss  a very low TWA, 5ppm under the OSHA
standard (9).   The Department of transportation requires  a "poison* label
(B).  Oral toxlcity for humans Is 140 og/kg as reported in RTECS.  The

     Formic acid is the third component of MS-lll. OUHTADS reports that it
blodegirades ooderately fast and is highly toxic via Ingestion or inhalation.
It is a strong irritant (8).  RTECS reports additionally that it may be a
mutagen.  The current OSHA standard is 5ppm TWA (9)*

AIM — OAKXTB.PRODUCTS, INC.

     Oakite ALM is an alkaline mixture(pH-13) of <5Z tributyl phosphate,
furfuryl alcohol <10Z, monoethanolaalne, 10Z and less than 1Z sodium
hydroxide.  Tributyl phosphate, is a widely used plasticizer  has 3000 mg/kg
LOSO in rats according to RTECS and one study reported 12600ag/kg for
teratogenic effects (9).  The TWA Is 200 ppb probably because of eye and
mucous membrane Irritation.

     Furfuryl alcohol is unstable in water (12) and should biodegrade well
according to OHtOADS.  OHMTADS also suggests moderate toxiclty for this
compound (8).  It is an eye and skin irritant and OSHA has set the TWA at
SOppm.  there is one outagen study reported in RTECS (9).

     Munoaminethanol is very strong eye and skin irritant and OSHA has set
the air standard at 3ppm TWA (9).  No other toxicological Information has
been reported-about this compound.  DOT considers it a corroaiva material
(8).

     Sodium hydroxide is a very minor component, probably added to achieve
the correct pH in the formulation.  It is a corrosive material according to
DOT (8).  chief routes of toxlcity is inhalation of dust from solids and
ingestlon (8).

     Overall, this formulation has no compounds that have been reported to
show long term health effects upon exposure to environmental levels. These
components however, do have a very high potential for serious health effects
in workers because of the corrosive nature of the material.  Use in a
properly ventilated system with  protective equipment would eliminate this
problem.

FUS — OAKITE PRODUCTS, INC.

     FUS contains 3SZ butyl cellusolve (2-butoxyethanol), 15Z formic acid,
(See MS-lll.) 10Z dllsobutyl ketone, less than 52 hydrofluoric acid and
dodecylbenzenesulfonic acid In 10Z mixed aromatic hydrocarbons (13).  The
mixture is acidic, pH is approximately 1.0.

     The principal ingredient, butyl cellusolve is a skin and eye irritant.
The OSUA standard is SOppm TWA.  Inhalation studies in rats show some
teratogenic effects at 200 ppm (9). (Reported in RTECS).  It is a poison
when ingested orally and may be absorbed through skin (8).  May degrade
moderately fast (8).
                                     104

-------
     Hydrofluoric  acid  Is  a corrosive material with strong  Irritation
potential.  The TCLo for *an by  Inhalation  is 110 ppa/lM and  it  is  a
suspected mutagen  and teratogen  (9).  OHMTADS reports that  natural
alkalinity will slowly  dissipate the acidity (8).   The OSHA Standard Is 3
ppm TWA.  DOT require a "poison,"  "poison gas" and  "corrosive" label (8).

     Dllsobutyl ketone  is  listed as a skin  and eye  Irritant by RTECS (9);  the
OSHA Standard Is SO ppm TWA, but 25 ppm has been recommended.  OHMTADS
reports that it is a olid  chronic  irritant  and inhalatlve toxin with low
degrees of hazard  to public health.  OHMTADS aljo claims that this like
other ketones should degrade well  in the environment (8).

     Oodecylbenzenesulfonlc acid is an irritant and is moderately toxic with
Ingestion.  DOT requires "Corrosive" label.  Has not shown  any chronic
Coxlclty in nan (8).

     Overall, this formulation hae no compounds that have been reported to
•how long tern health effects upon exposure to environmental levels. These
components however, do have a very high potential for serious health effects
to workers because of the corrosive nature of the material.  Use in a
properly ventilated system with  protective equipment would eliminate this
problem.
