SUBJECT Follow up of today's discussion on tooling resins for boat and reinforced plastics tools. 
P.3

COMMENTS 

Thank you for your time discussing your issues with tooling resins. I also appreciate your agreeing 

to send additional information. 

The type of information that would better help us address this issue is: 

1) What are the particular requirements for tooling resins (please be as specific as possible, for 

example put a specific temperature and/or strength characteristic which needs to be met)? What 

types of environments are tooling resins exposed to? (Note that since the tooling gel coat is above 

the tooling resin, the tooling gel coat may be exposed to mold release agents and mold stripping 

agents, but not the resin part of the tool, therefore it doesn't seem that the resin part of the tool 

comes in contact with any chemicals which may be considered corrosive). 

2) What other resins besides iso-polyester resins can be used to meet the above requirements and 

(please be as specific as possible) what is the cost differential between these and the isopolyesters? 

3) What distinguishes the low styrene tooling resins used in the boat industry (eg: Ashland's AME 

5000, Alpha Owens Corning Hydropel A-35 polyester resin/vinyl ester resin blend ) from tooling 

resins used in the reinforced plastics industry? 

It would greatly help to get the above information before October 8, 1998. 

In addition, we would like to add North End Composites to both the reinforced plastics and boat 

databases. This will ensure that we analyze the economic impacts of your facility. In order to do 

this we would need: 

For your BOAT manufacturing operations (includes making boat tools): 

Annual usage and HAP content (if material contains more than one HAP, please break it out) of 

each material used for production resins, tooling resins, pigmented gel coats, clear gel coats, 

tooling gel coats, base coat (enamel) gel coats, carpet and fabric adhesives, wood finishes, 

topside/deck surface coatings, bottom coatings. 

For resins, we also need application method (flow coater, spray gun, bucket and brush, etc.) 

If more than one application method is used, we would need a percentage for each (see the boat 

data summary tables on my website) 

For your Reinforced Plastics manufacturing operations: 

Amount and HAP content and method of application of each material used in: 

tooling resins, filled non corrosion application production resins, unfilled non corrosion application 

production resins, resins for corrosion applications 

And, amount and HAP content of pigmented gel coats, clear gel coats, tooling gel coats 

Please let me know when you would be able to provide the above information to add to our 

database. 

Thank you again for your time and your discussion, and your pursuit of lowering £v^/6:tOfi/C,,
