BECKOPOX™ EH 624

BECKOPOX™ EH 624 serves as a liquid catalyst within the CASE Ingredients framework. Tailored for the building and construction and paints and coatings sectors, its applications encompass decorative paints and finishes, primarily solventborne coatings. This product features a free-phenol content of less than 5%, facilitating curing at temperatures as low as 5°C. It excels at providing good chemical resistance and acts as an accelerator for low-reactive hardeners in coatings, adhesives, and laminates.

Special Properties and Uses

Free-phenol-content <5%, curing at temperatures as low as 5°C. Good chemical-resistance. Coatings, adhesives, laminates. Accelerator for low reactive hardeners.

Suggested Uses and Processing Information
  • In combination with liquid epoxy resins BECKOPOX™ EH 624 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 43 g BECKOPOX™ EH 624 starts to gel at 23°C after approx. 20 - 25 minutes.
