Epoxy Resin EPIKOTE™ L 20 + EPIKURE™ Curing Agent 943 (100-200 min)

Set of 2 components

The combination of Epoxy Resin EPIKOTE™ Resin L 20 and Hardener EPIKURE™ Curing Agent 943 yields an extremely low-viscosity epoxy resin system of medium reactivity and superior impregnating and wetting properties to glass, aramid, and carbon fibres.

Application:
Owing to its impressive impregnating properties, it is most often used for winding methods in the manufacture of high-strength fibre composite components.

Processing:

Processing time (from 20 °C up to 25 °C): 100 - 200 minutes

Mixing ratio:
100 : 24 parts by weight of EPIKOTE™ Resin L 20 : EPIKURE™ Curing Agent 943

Curing time:

  1. 8 - 10 h at room temperature, followed by 8 - 10 h hot curing at 60 °C
  2. To shorten curing: 3 h at 30 - 40 °C + 8 -10 h at 60 °C
  3. For greatly enhanced thermoforming stability (TG approx. 110 °C):
    Curing as in 1. or 2. + post curing 6 - 10 h at 120 °C with a temperature heating rate of 20K/h.
