Epoxy Resin L + Hardener GL 1 (30 minutes), set of two componets
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.
Processing time: approx. 30 minutes
Mixing ratio:
100 : 30 parts by weight resin : hardener
100 : 35 parts by volume resin : hardener
Properties:
- Low viscosity (820 mPas at 25 °C)
- 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 delevoped 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 mechanical and physical properties, to perform a post-curing at least at 40 °C over 15 h.

The mixing ratio of 100: 30 resin to hardener remains unchanged.
