Assortment adjustment. This discontinued item is qualitatively perfect goods without defects. Sale while stocks last.

Westlake has discontinued the production of the hardener EPICURE EPH 161. Our hardener LT (old designation R&G EPH 161) is a product that has similar properties to the original Westlake hardener, but does not correspond to it.

  • Better impregnability of reinforcing fibers
  • Better milling edge quality
  • Higher stiffness (+ approx. 17 %)
  • Tendency higher strength

Epoxy Resin L + Hardener LT

The Epoxy Resin L + Hardener LT system is very suitable for bonding wood, metal and PS rigid foams such as Styropor® due to its low surface tension, good adhesion and low curing shrinkage. It can be processed in all common methods such as hand laminating, pressure and vacuum impregnation as well as pressing and wrapping.

Processing at room temperature with subsequent heat curing for approx. 15 h at 60 °C

Epoxy resin L with Hardener LT has excellent mechanical properties, such as those required in aircraft construction. However, it does not have aviation approval.

Processing time: 90 minutes

Mixing ratio:
100 : 25
parts by weight of resin to hardener
100 : 29 parts by volume of resin to hardener

Curing time:
24 hours at room temperature, subsequent warm curing optional

Heat distortion temperature:
max. 70 °C with 24 hours/23 °C curing
max. 120 °C with additional 15 h hot curing at 100 °C
(Values may vary depending on laminate thickness and fibre content)


Epoxy Resin L 20 + Hardener LT

Processing time: 90 minutes

Mixing ratio:
100 : 25
parts by weight of resin to hardener
100 : 29 parts by volume of resin to hardener

Curing time:
24 hours at room temperature, followed by approx. 12 hours of hot curing at at least 60 °C

Heat distortion temperature:
max. 70 °C with 24 hours/23 °C curing
max. 120 °C with additional 15 h hot curing at 100 °C
