COR61-AA-930KS is a DCPD laminating resin specially designed for use in medium to thick laminates such as boat hulls
and decks and for excellent bonding to acrylic substrates.
COR61-AA-930KS contains a maximum of 35% styrene (HAP) by weight, which meets the EPA 40 CFR Part 63
requirements of the National Emission Standards for Hazardous Air Pollutants (HAP) for boat manufacturing and National
Emissions Standards for Hazardous Air Pollutants: Reinforced Plastics Composites Production: Non-Corrosion and/or Not
High Strength. The application method for both EPA standards is non-atomized spray.
FEATURES BENEFITS
Low Exotherm & Even Cure, Even in Thick Sections Improved cosmetics
Excellent Glass Wetting Easier to remove air during roll-out
Good Trim Time Allows for good working time
Less Than 35% HAP (Styrene) Content MACT compliant for Non-Atomized Spray-Up; fewer

Testing conducted at 77 F (25 C) and 50% relative humidity. Results may depend on post-cure and batch variations within nominal blend component compositions.
The air-curing capabilities of DCPD laminating resins are well documented. Ambient temperature, catalyst level, laminate thickness and configuration can all contribute to
accelerating and surface cure. Care must be taken to ensure that secondary laminates have good adhesion. Cured surfaces should be sanded between laminates.

The air-curing capabilities of DCPD laminating resins are well documented. Ambient temperature, catalyst level, laminate thickness and configuration can all contribute to
accelerating surface cure. Care must be taken to ensure that secondary laminates have good adhesion. Cured surfaces should be sanded between laminates.
