Haprez™ 3749

About
A high performance, low pot life, heat curing laminating system that is specifically formulated for all other applications requiring laminates for use up to 350° F. Ideal for oven cure, vacuum bag or pressure cure processing. Provides excellent wetting characteristics on fiberglass cloth, and its smooth handling and spreading quality make it quick and easy to use. Its low viscosity characteristics also enables hand application by brush, roller, squeegee, or conventional internal mix spraying equipment. Non-settling during storage and use, to yield completely uniform results with every use. It is also non-sagging to insure that the glass stays in place during fabrication and curing, and its long pot life characteristic enables continuous, non-stop laminating to any desired thickness. Should be used with a HAPCOAT system to provide a totally compatible laminate system&&
