A two part, room curing, laminating system, that provides excellent performance results at all operating temperatures up to 300°F. As such, it can be used for room temperature applications, as well as in critical high heat conditions.

Easy to mix, gels rapidly, and provides excellent wetting or chopped or woven fiberglass. It is suitable for hand lay up, or can be sprayed with conventional internal mixing equipment.

May be used in combination with a HAPCOAT surface coat system to provide a totally compatible laminate.

Typical applications for HAPREZ 3748 are in vacuum forms, holding fixtures, rim molds, autoclave, vacuum bag molding, and any other applications where a strong laminate is necessary.
