Applications & Uses

Suggested Uses and Processing Information

In combination with liquid epoxy resins BECKOPOX™ EH 624/90X is especially suited for formulating very well chemical resistant container linings, flooring compounds and coatings for steel structures. The curing agent has a high reactivity in thin films as well as in highly filled systems. Even at low temperatures and high humidity a hard tack-free surface is obtained. It is also used for improving the reactivity of cycloaliphatic polyamines such as BECKOPOX™ EH 637.

MIXING RATIO AND POT LIFE

A blend of 100 g BECKOPOX™ EP 140 and 48 g BECKOPOX™ EH 624/90X starts to gel at 23°C after approx. 35 minutes.
