Haprez™ 3745 is a clear, high temperature, laminating resin and binder.
- A room curing, unfilled polymer system that can be used as a multi-purpose laminating resin for applications demanding up to 400°F. resistance.
- Its excellent handling characteristics make it easy to mix and use, and HAPREZ™ 3745 gels rapidly, and provides excellent wetting of chopped or woven fiberglass. It is suitable for hand lay-up, or can be sprayed with conventional internal mixing equipment.
- HAPREZ™ 3745 can also be filled with high loadings of sand, aluminum, or walnut shells for casting and mock-ups requiring higher temperature application.
