Cycloaliphatic Amine Curing Agent

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.

FEATURES

High temperature resistance
High mechanical strength
Excellent chemical and moisture resistance
Low color and good color stability

APPLICATIONS

Structural adhesive
Flooring, grout, coating, etc. in construction
Composite lamination
Casting and encapsulation
Heavy duty protective coating
