Epoxy Resin L + Hardener CL (60 min)

Epoxy Resin L + Hardener CL (60 minutes), set of two components

The resin system is curing at temperatures over 20 °C but develops no distinctive brittleness even at curing temperatures below 20 °C (for at least 48 h). We however recommend, to improve the mechanical and physical properties, to perform a post-curing at least at 40 °C over 15 h.

It is suitable for the following processing procedures:

• Hand laminating
• Vacuum moulding
• Press moulding

Expertise for the resin system Epoxy resin L + Hardener CL: this system is not cytotoxic (cell damaging), important for applications in medical purposes!
