- Coating Type
- Special Properties and Uses
Relatively low yellowing-tendency. With liquid epoxy resins for self-leveling flooring compounds, casting compounds and laminates.
- Suggested Uses and Processing Information
- BECKOPOX™ EH 637 is a modified polyamine with very low viscosity, for use together with liquid epoxy resins for flooring compounds with good chemical resistance and low yellowing tendency.
- For thin walled laminates a post cure of 2-3 hours at 40-50°C is necessary prior to deforming.
MIXING RATIO AND POT LIFE
A blend of 100 g BECKOPOX™ EP 140 54 g BECKOPOX™ EH 637 starts to gel at 23°C after approx. 45-60 minutes.
