Zepoxy REH 243
Zepoxy REH 243 is a cycloaliphatic amine based curing agent with low viscosity and moderate reactivity. It can be blended with other amine-based hardeners or with epoxy accelerators to achieve ambient curable epoxy compositions. As a sole curing agent, Zepoxy REH 243 can yield epoxy systems with relatively high heat distortion properties when properly cured.
