HAPREZ 3742 Hapco Inc. Thermoplastic, Unspecified

Product Description

An amber clear, general purpose, and economical system that be used as is, or with a variety of fillers, for virtually all room temperature casting and laminating applications.

As a laminating system, the extremely low viscosity of HAPREZ 3742 provides superior penetration and wetting of the fiberglass, and makes it especially advantageous for spraying with chopped fiberglass.

For casting, HAPREZ 3742 may be used unfilled for casting small, amber clear parts, or it may be heavily filled with sand for making throwaway molds and mock-ups. Larger parts can also be cast with high loadings of aluminum, and walnut shells for low cost and machinability, or with wood flour for making tooling putty.

HAPREZ 3742 is one of our most versatile products, and can be used almost universally in all room temperature applications.
