EPIKURE™ Curing Agent 3300


EPIKURE™ Curing Agent 3300 is a very low viscosity, light colored cycloaliphatic amine curing agent for use in formulating heat cured epoxies. Isophorone diamine can be blended with other amine-based hardeners or with epoxy accelerators to achieve ambient curable epoxy compositions. As a sole curing agent, EPIKURE Curing Agent 3300 can yield epoxy systems with relatively high heat distortion properties when properly cured.
