Epoxy Resin L + Hardener GL 1 (30 min)

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.
