Hardener GL 1 (30 min)

Hardener for Epoxy Resin L

Low viscosity (100 ± 50 mPa•s at 25 °C)

The well-proven R&G Epoxy Resin L in combination with Hardener GL 1 offers an approval by the Germanische Lloyd for the construction of boats and rotor blades for wind turbines.

Epoxy Resin L + Hardener GL 1

Mixing ratio:
100 : 30 parts by weight resin : hardener
100 : 35 parts by volume resin : hardener

Processing time: approx. 30 minutes

Properties:

Low mixing viscosity (820 mPa•s at 25 °C)
Gardner color code <5
Fully cures at 10 °C
Glass transition temperature (Tg) > 80 °C (post-curing at 70 °C / 15 h)
Ambient curing does not result in brittleness (at 20 °C)
High static and dynamic strength

This newly developed resin system is ideal for wetting-out glass, aramid and carbon fibres. It exhibits a very good price/performance ratio and is suitable for the following processing procedures:

Resin infusion (RI)
RTM (resin transfer moulding)
Press moulding
Vacuum moulding
Filament winding
Hand laminating

The resin component itself is absolutely free of crystallization due to its Bisphenol A/F base! The resin system is ambient curing and develops no distinctive brittleness even at curing temperatures below 20 °C. We however recommend, to improve the physical and chemical properties, to perform a post-curing at least at 40 °C over 15 h.
