1.0 INTRODUCTION
Many manufactured items are painted or coated in order to protect the substrate, enhance
the appearance of the product, or both. Conventional liquid paints and coatings contain a
substantial quantity of organic solvent that evaporates during the curing or drying of the coating.
Consequently, surface coating operations are a major source of Hazardous Air Pollutant (HAP)
and Volatile Organic Compound (VOC) emissions. According to recent estimates, air
emissions from industrial surface coating operations in 1992 accounted for nearly 24 percent of
all VOC emissions to air from industrial processes (U.S. EPA 1993). This equaled more than 2.6
million tons (2.4 million metric tons) of VOCs.
As coatings users come under increasing pressure from environmental regulatory
agencies to reduce their emissions of HAPs and VOCs, coatings suppliers are rapidly
developing new lines of low- and no-VOC/HAP coatings. Due to the pace of new product
development, coatings users, particularly small businesses, frequently are not aware of new
products and of the degree to which these products can reduce their process emissions. Even
when businesses are aware of new coatings, they may question whether these products can

16. ABSTRACT
The paper summarizes progress in development of the logic framework for a proto-
type Coating Alternatives GuidE (CAGE) system to assist the end user with sorting
through information about lower-emitting coatings. The goal of this work is to devel-
op a computer-based tool that coating users, and those providing technical assis-
tance to them, will be able to use to select technically appropriate, cost-effective,
and low-emitting coatings. CAGE is designed to provide information on coating equip-
ment and chemistries in a user-friendly decision-tree format. The initial focus is
on developing CAGE to provide information about alternative coatings for metal
parts and products painting. CAGE is being developed in three phases: (l) develop-
ment of a prototype system using a limited set of coating options, (2) testing the pro-
totype logic system with the help of coating users and state and local pollution pre-
vention assistance offices, and (3) expansion of CAGE to include additional coatings
and detailed information about coating options.

meet their operational, aesthetic, and performance requirements.
To assist the end user with sorting through information about lower-emitting coatings,
Research Triangle Institute (RTI) is working in cooperation with the U.S. Environmental
Protection Agency's Air and Energy Engineering Research Laboratory (AEERL) to develop the
Coating Alternatives Guide (CAGE). The goal of this work is to develop a computer-based tool
that coating users, and those providing technical assistance to them, will be able to use to select
technically appropriate, cost-effective, and low-emitting coatings. CAGE is designed to provide
information on coating equipment and chemistries in a user-friendly decision-tree format.
The technical effort is focused initially on developing CAGE to provide information
about alternative coatings for metal parts and products painting. CAGE is being developed in
three phases:
1)	development of a prototype system using a limited set of coating options,
2)	testing the prototype logic system with the help of coating users and state and
local pollution prevention assistance offices, and
3)	expansion of CAGE to include additional coatings and detailed information about
coating options.
This paper summarizes progress in development of the logic framework for the prototype CAGE
system.
2.0 THE CAGE CONCEPT
The traditional approach to providing information to smaller businesses generally focuses
on gathering information on a topic and creating a written document which is then made
available through business assistance hotlines, resource centers, and other distribution systems.
Unfortunately, written documents generally have limited utility for meeting the information
needs of a small business. Reasons for this include the difficulty of getting the information to the
intended audience, incomplete information, information in excess of that needed by the user, and
difficulty in keeping the information current.
The difficulties in gathering and distributing coatings information suggest an information
diffusion approach based on electronic information media. The development of CAGE is based
on the premise that an electronic information base available for personal computers can serve as
an effective tool to assist coatings users (and the organizations that provide technical assistance
to them). These users need not only information about the coating chemistries that can reduce
emissions from coating operations, but also expertise to help focus their search on those coating
chemistries that can best meet their specific performance and other requirements. Consequently,
CAGE is being developed to meet both needs (i.e., to provide information about a variety of low-
emitting coatings and to provide relative rankings, based on user input, of coatings that are most
likely to meet the user's performance requirements). This allows the user to narrow the search
for coatings and focus on those coating types most likely to apply to that business's
manufacturing operations.
