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.
