Hardener for Epoxy Resin L
The resin system Epoxy Resin L + Hardener CL yields superior impregnating and wetting properties towards carbon, glass, aramid and natural fibres. It is especially suitable for carbon coating of automotive parts.
- High degree of UV stability
- Tack-free curing even of thin layers
- Glass transition temperature (Tg) > 90 °C (post-curing at 70 °C / 15 h)
- High static and dynamic strength (equal to Epoxy Resin L 285 with Hardener 285)
- Free of nonylphenol and DETA
Processing time: 60 minutes (100 g / 20 °C)
100 : 30 parts by weight resin : hardener
100 : 35 parts by volume resin : hardener
The resin system is ambient curing and develops no distinctive brittleness even at curing temperatures below 20 °C (for at least 48 h). We however recommend, to improve the physical and chemical properties, to perform a post-curing at least at 40 °C over 15 h.
It exhibits a very good price/performance ratio and is suitable for the following processing procedures:
- Hand laminating
- Vacuum moulding
- Press moulding
