FOREWORD
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.

SECTION 1
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.
-------
SECTION 3
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.

SECTION 4
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.
-------
SECTION 5
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
navy gray enamel and various epoxy paints including Chemical Agent Resistant
Coatings (CARC). Zinc chromate primer used in many of the coating systems
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
17
-------
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
21
-------
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

APPENDIX A
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).

Punctional requirements of the Bench Scale Testing —
—«-—• »•
Establish a base lice for evaluation by processing a set of
samples through the bench scale stripping operation using MS-
111 and evaluating the surface condition resulting for
submergence times of 10, 20, and 30 minutes.
Evaluate the surface condition resulting from the processing of
samples through the stripping operation using each of the
candidate stripping formulations and compare the results with
those obtained using MS-HI for each of the three
submergence times*
28
-------
o Evaluate the surface condition resulting from the processing of
samples wlch 'aged' coatings throccth the stripping operation
using MS-lll and the three moat promising stripping
formulations as recommended by the contractor and
approved by CARLTECH.
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
evaluation of the surface condition of samples following the stripping
tests.
29
-------
5* The timely procureaenC of an adequate quantity of all candidate
paint stripping formulations to be used in the testa.
6. Photographic equipment suitable for producing pictures of saoples
at lOx oagnification.
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.
COST PROPOSAL
It is the Intention of CARLTECH to negotiate a firm fixed price
contract .>r the work described in this test specification. Since the exact
number c KMnt stripping formulations to be tested is not known at the time
of this solicitation, the cost proposal should be presented In two parts as
follows:
o A firm fixed price must be proposed for the design, fabrication,
procurement and installation of all equipment, materials, and
supplies required to carry out the bench scale test program.
o A firm fixed unit price oust be proposed for the complete testing,
data analysis, and sample evaluation of a single stripping
formulation. This unit price will not Include the coot of
procuring the specified stripping formulation, since the final
selections of strippers will not be made until Just prior to
contract award and the allowable cost will be negotiated at that
time.
It should be noted that any item of equipment which muat be purchased
specifically for the performance of work under this contract, the price of
which la charged to this contract, will become the property of CARLTECH,
and Its disposition at the end of the contract will be determined by
CARLTECU.
SELECTION CRITERIA
The following criteria will be used in selecting a contractor for this work:
A. Willingness to follow all contractual obligations as outlined '.n this
solicitation;
31
-------
B. Immediate availability of facilities adequate for performance of the
specified testa;
C. Curriculum vltae and capabilities of the personnel proposed;
D. Record of performance on similar projects;
E. An evaluation of the probable total cost for the project based on the
contractor's proposal; and
F. The availability of backup analytical capabilities at the test site.

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.

-------
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.
