Contact Summary: 

This contact report supersedes the January 29,1998 contact report documenting the telephone 

conversation between Mr. Jemison and Mr. McCloskey. 

Mr. John R. McCloskey was contacted on behalf of the U.S. EPA to update information 

provided in the 1993 EPA Reinforced Plastic Composites Screening Survey submitted by 

Composites USA, Inc. for their facility located in Bear, Delaware. In response to my questions Mr. 

McCloskey indicated the following: 

The facility has moved from Bear, Delaware to Northeast, Maryland. 

The facility makes corrosion resistant piping, ducting, and process vessels for the chemical, 

pulp & paper, pharmaceutical, and semiconductor industries. 

The facility uses several processes to make the corrosion resistant products discussed above. 

These processes include manual resin application (bucket & brush), mechanical resin application 

(pressure-fed rollers, chop-hoop filament winding), and helical filament winding. Helical filament 

winding involves the wetting of reinforcement by drawing the continuous glass reinforcement 

through a resin bath prior to the reinforcement being wound on a rotating mandrel. In chop-hoop 

filament winding, dry continuous glass reinforcement is helically wound on a mandrel (perpendicular 

to the axis) in a thin "wet bed" of resin and chopped reinforcement Hie "wet bed" of reinforcement 

is applied to the mandrel using a spray gun (chopper gun) that feeds 1 or 2 strands of continuous 

glass reinforcement thorough the spray gun chopper mechanism during the resin application. 

During the 1997 calender year, the polyester and vinyl ester resins applied by these 

fabrication devices contained approximately 43.6% HAP by weight (on average, for all fabrication 

techniques) and do not contain vapor suppressants. The only HAP present in these resins is styrene. 

The facility occasionally adds small amounts of styrene to these resins and these small amounts are 

reflected in the average HAP content mentioned above.

Mr. John R. McCloskey 

Page Two 

November 20 J1998 

Mr. McCloskey could not provide a separate weighted average HAP content for each 

individual fabrication technique (i.e. manual resin application, mechanical resin appUcation, and 

helical filament winding) because the facility does not record the exact amount of each resin that it 

appUes through each fabrication process. For mechanical resin application, Mr. McCloskey 

estimated that 1/3 ofthe total resin is applied using pressure-fed rollers and 2/3 ofthe total resin is 

applied with the spray gun utilized during the chop-hoop filament winding process. Mr. McCloskey 

emphasized that this was a very rough estimate and stated that the facility could not provide exact 

numbers because, as noted above, the facility docs no! record the exact amount of each resin that it 

applies thorough each fabrication process. 

The particular resin used by the facility is dependent on both the chemical environments) 

the product will be exposed to and the specifications ofthe product customer. The facility uses the 

same resin to make a particular product, although the product may be made using different 

fabrication processes. For example, a storage tank may be made using both hand lay-up and helical 

filament winding, but the resin applied using both processes will be the same resin. 

The facility conducts mixing operations for the purpose of mixing promoter with the resin. 

The mixing is,conducted in the same 55 gallon drum the resin was shipped in by inserting a mixing 

shaft through the bunghole on the top of the 55 gallon drum.
