Epoxy Resin L + Hardener GL 2 (210 minutes), set of two components
Approval by the Germanische Lloyd for the construction of boats and rotor blades for wind turbines.
Mixing ratio:
100 : 30 parts by weight Epoxy Resin L : Hardener GL 2
100 : 35 parts by volume Epoxy Resin L : Hardener GL 2
Processing time: approx. 210 minutes*
*Measured with Gelnorm® gel timer: 100 g at 20 °C = approx. 210 minutes processing time).
(Temperature rise in the cup from 23 °C to 40 °C at 100 ml approx. 109 minutes
Properties:
- Extremely low-viscous (Mixing viscosity 250 mPas at 25 °C)
- Highly transparent (Colour index < 1 Gardner)
- Fully cures at 15 °C
- Glass transition temperature (Tg) > 85 °C (post-curing at 70 °C / 15 h)
- Ambient curing does not result in brittleness (at 20 °C)
- High static and dynamic strength
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.
However, in order to improve the mechanical and physical properties, we recommend heat curing at a minimum of 40 °C for 15 h.
