Creating a High Temperature Tool Using EpoxAmite™ HT and EpoxAcoat™ HT

Overview

High temperature tooling resins play an important role in creating composite parts and are a low cost alternative to metal molds. Tools often require high heat resistance for high-temperature curing pre-pregs/high-temp cured resins.

EpoxAcoat® HT is a slightly thixotropic epoxy gel coat that offers high heat resistance (post cure required). Cured epoxy is tough and offers exceptional abrasion resistance. This surface coat will wet out well over a variety of surfaces with good sag resistance. Applications include laminating, precision tooling, master and pattern making, core boxes and fixtures.

EpoxAmite® HT High Temperature Laminating Epoxy is a water clear, UV resistant laminating epoxy that resists high temperatures up to 300°F / 149°C when properly cured. Pot life is 1 hour and cure time is 24 hours at 73°F / 23°C (post cure required – see post cure schedule). Ultra-low viscosity ensures uniform wetting out and fast penetration of reinforcement materials during hand lay-up or vacuum infusion processes. Cured resin offers superior physical properties. EpoxAmite® HT High Temp Laminating Epoxy can be used with S-Glass, E-Glass, Kevlar and carbon fibers for making composite tooling or parts. Applications include making high temperature pre-preg parts, bonding fixtures, vacuum form molds and prototype injection molds.
