BECKOPOX™ EH 624/90X contains less free phenol than BECKOPOX™ EH 629 and shows better early-water-resistance. This delievery form is not suitable for solvent free systems.
Applications & Uses
- Applications
- Coating Type
- 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.
