High Strength Epoxy Hardener
Back to
Hardener page
Product Description:
Novel modified cycloaliphatic hardener. High strength, low viscosity curing agent with long pot life, fast thin film set time, and high HDT after post cure. Cures sufficiently at ambient temperatures for unsupported post cure. Contains no solvents, 100% solids.
Product Uses:
Hand lay up laminating, tooling, RTM, epoxy injection and infusion. Potential for press molding and VARTM composite molding. Provides higher than normal HDT with diluted resins.
