Epoxy resin EPIKOTE™ L 20 + hardener EPIKURE™ 111
Working pack
The epoxy resin system EPIKOTE™ Resin L 20 with hardener EPIKURE™ Curing Agent 111 is a low-viscosity, cold-curing epoxy resin system with excellent impregnation and wetting properties for glass, aramid and carbon fibers.

Application:
The system is suitable for the lay-up process. The high reactivity of the resin system enables a short dwell time in the mold, especially for difficult laminates and sandwich structures. The system is used in particular in glider and boat construction, for example.

Processing:
Processing time: 10 - 15 minutes

Mixing ratio:
100 : 27 parts by weight epoxy resin EPIKOTE™ Resin L 20 : hardener EPIKURE™ Curing Agent 111

Curing time:
After curing at room temperature, post-curing at 50 - 60 °C can be carried out to improve the deformation temperature under load.
