Mr. Steve McNally, Director of Government Affairs 

Composites Fabricators Association 

8201 Greensboro Drive, Suite 300 

McLean, Virginia 22102 

Dear Mr. McNally: 

The purpose of this letter is to provide the information that you requested during the 

January 5, 1998 meeting. The first action item was to send you a list of "questionable corrosionresistant" products diat meet the proposed industry definition for corrosion resistance. The 

second action item was to provide two telephone contact reports documenting the use of a flow 

coaters to apply gel coat. 

We reviewed the corrosion-resistant definition that was provided by industry 

representatives in the October 21,1996 meeting (Enclosure 1). We then examined the industry 

screening surveys to determine which facilities may be considered to produce corrosion-resistant 

products based on your proposed definition. 

Enclosure 2 contains selected pages of some ofthe surveys that potentially present 

facilities with corrosion-resistant applications. All facilities in Enclosure 2 use premium resins as 

defined in condition one of your definition. In addition, it could be argued that the products 

produced require increased chemical inertness or resistance to chemical attack as defined in 

condition three of your proposed definition. It is unknown if any ofthe products are 

manufactured to an accepted standard for corrosibri-resistant or food contact application, which is 

described in condition two ofthe definition. However, since only two ofthe three conditions 

have to be met based on your definition, the products produced by facilities in Enclosure 2 would 

probably all meet your proposed corrosion-resistant definition. 

Some ofthe products presented in Enclosure 2 such as tanks and pipes may belong in the 

corrosion-resistant database, whereas other products such as pools, spas, and bath tubs should 

probably not be considered corrosion-resistant. Other products such as molds, ventilation 

equipment, cooling tower covers, utility boxes, grating, and water tanks may be in a gray area and 

not easily classified as either corrosion or non corrosion-resistant.

P.3 

Hopefully this information will be useful to you in better defining corrosion-resistant 

products. We believe that conditions two and three, in particular, need to be more clearly 

defined. The terminology "such standards include..." and "such applications include..." is too 

vague to clearly define corrosion-resistant applications. 

Enclosure 3 contains two telephone contact reports documenting conversations where 

reinforced plastic composites facilities indicated use of flow coaters to apply gel coat. As you 

can determine from the reports, the material applied in both cases has clearly been identified as gel 

coat and not as resin. Mr. Lacovara indicated during the meeting that he would like to follow up 

on these reports and confirm that the gel coat is, in fact, applied by flow coaters. 

If you have any questions concerning the enclosed material, please call me at 

(919) 541-5254 or Melanie Proctor at (919) 941-0333.

Draft proposal 

MACT subcategory for the manufacture of 

corrosion-resistant composite products 

Introduction 

While composites in general will not rust or degrade under normal 

conditions, many composite products are specifically formulated and 

produced for applications requiring higher levels of chemical 

purity and/or resistance to corrosion. Such applications include 

waste water treatment, pollution control, metal plating, food and 

drug processing, pulp and paper production, chemical processing, 

and many others. 

These "corrosion resistant" applications often require special 

resins and/or manufacturing technologies to ensure that the 

resulting product is sufficiently chemically resistant or inert. 

The use of these special resins and technologies are often 

incompatible with emission reduction methods commonly used 

elsewhere in the composites industry. For example, corrosion 

resistant composite products often cannot be economically 

manufactured using low-VOC, emission-suppressed, or highly-filled 

resins. 

Subcategory definition 

A composite product shall be considered "corrosion resistant, " and 

the manufacture of the product shall be included in the corrosion-
P.5 

resistant MACT subcategory, if any two of the following three 

conditions are satisfied. 

1. The product is «a€kr with n premium resin^ or is post-cured at 

temperatures above 100 dea. C. Premium resins include 

isophthalic polyester,M vinyl ester, .fumarate polyester, 

n A 

chlorendic acid polyester, and novolac vinyl ester. 

2. The product is manufactured to an accepted standard for 

corrosion-resistant or food contact applications. Such 

standards include ASME RTP-1; ASTM D5364, -6-502-, D3299, D4097, 

D2996, D2997, D3262, D3517, D37$4, D3840, D4024, D4160, D4161,>.yftZ, 

D4162, D4163, D4184; ANSI/AWWA C950; fa"* See*-*** *2 3<?/ 

3. The product is manufactured specifically for an application 

that requires increased chemical inertness or resistance to 

chemical attack. Such applications include products intended 

for use in chemical processing* pulp and paper, sewer and 

waste water treatment, potable water, food and drug 

processing- \ pollution or odor control, metals plating,

Gruber Systems manufactures fiberglass molds for the 

cultured marble industry. The manufacturing process consists 

of gelcoating and hand laminating of fiberglass molds. Both 

polyester and vinyl ester gelcoats and resins are used in 

the mold making process. 

We also manufacture a granite-like filler which we package 

and sell for use by our customers. The process consists of 

casting aluminum trihydrate filled polyester casting resin 

in various colors. The polymerized/cured, colored resin is 

then ground into various sized granules and blended into a 

dry filler for granite looking solid surface material. 

Gelcoat and Resin make-up is as follows: 

Polyester gelcoat - approximately 

Vinyl ester gelcoat - approximately 

Polyester laminating resin 

Vinyl ester laminating resin

Contact Report 

From: Robert Jemison, P^ific Environmental Services, Inc. (PES) 

Date: November 25,1997 

Contact: Mr. Ben Bichler 

Company: Delta Fiberglass Structures, Inc. 

Telephone Number: (801) 977-0091 

Fax Number: (801) 977-0095 

Contact Summary: 

Mr. Ben Bichler was contacted to update information provided in the 1993 EPA Reinforced 

Plastic/Composites Screening Survey submitted by Delta Fiberglass Structures, Inc. for their facility 

located in Salt Lake City, Utah. In response to my questions Mr. Bichler indicated the following: 

The facility uses hand lay-up in the fabrication of certain products. The polyester resin used 

contains approximately 41% styrene by weight. No additional styrene is added to this resin in the 

fabrication process. 

The facility uses non-atomized mechanical spray-up (i.e. a flow-chopper or flow-coater) in 

the fabrication of certain products. Both the polyester and vinyl ester resins applied by this device 

contain approximately 41% styrene by weight. No additional styrene is added to these resins in the 

fabrication process. 

The facility uses non-atomized mechanical spray-up (i.e a flow-chopper or flow-coater) to 

apply a polyester gel coat in the fabrication of certain products. The polyester gel coat contains 

approximately 40% styrene by weight. No additional styrene or methyl methacrylate is added to this 

gel coat in the fabrication process.

Contact Summary: 

Mr. Earl H. Miller was .contacted to update information provided in the 1993 EPA Reinforced 

Plastic/Composites Screening Survey submitted by Millennium Products* Inc. for their facility 

located in Elkhart, Tndiam In response to my questions Mr. Miller indicated ine following: 

The facility still uses the hand lay-up fabrication process but only for repairs. The volume 

of resin used by diis fabricjuion technique is inconsequential compared to die volume used in 'tile 

non-atomized mechanical spray-up fabrication process. The tooling resin and tooling gel coat used 

during the hand lay-up fabrication process both contain approximately 3 8% styrene by weight. No 

additional styrene is added to the resin in this fabrication process. No additional sryrene or methyl 

methacrylate is added to the gel coat in this fabrication process. 

The facility uses non-atomised mechanical spray-up (i.e. a flow-coater) in the fabrication of 

certain products. The polyester resin applied by diis device contains approximately 38% styrene by 

weight No additional sryrene is added to this resin in the fabrication process. 

The facility uses non-atoroized mechanical spray-up(i.c. a flow-coater) to apply a polyester 

gel coat iu the fabrication of certain products. The polyester gel coat contains approximately 3 8% 

styiene by weight No additional styrene or methyl methacrylate is added to this gel coal in the 

fabrication process.
