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.
Use as a backup laminating resin for EpoxAcoat™ HT high temperature surface coat epoxy.
