Hardener GL 1 (30 min)

Hardener for Epoxy Resin L

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.

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

Processing time: approx. 30 minutes

Properties:

  • Low viscosity (820 mPas 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.
