Long Pot Life Epoxy Hardener
Back to
Hardener page
Product Description:
A modified cycloaliphatic amine, high-performance and ultra-low viscosity hardener developed for resin infusion and related processes. Provides greater than 7-hour gel time, very high Tg properties after post cure, and a low exotherm temperature. Mix ratio 100:35 phr by weight. JEFFCO 4120 is solvent-free, 100% solids.
Product Uses:
Composite parts and tooling produced by resin infusion, vacuum bagging, and RTM. Also used where a very low mixed viscosity or long pot life is desired. |
