Heat resistant epoxy system SR1660 / SD7820 with slow hardener
Each kilo includes 0.76 kg resin + 0.24 kg hardener
Epoxy system developed for high service temperature tooling from 120°C up to over 200°C continuously depending on the chosen hardener. It exhibits excellent chemical resistance, resistance to oxidization and low exothermic peak. Suitable for laminating, press moulding, casting or injection.
Slow hardener SD7820:
Epoxy system for parts or tooling with a service temperature up to 120°C, 160°C peak.
Applications:
Composite tooling for "120°C" prepreg, thermoforming tooling or structural parts with a high service temperature.
