Product Description
  • 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.
