Epoxy Resin L + Hardener GL 2 (210 min)

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.

Processing times with Epoxy Resin L depending on the proportion of hardener GL 1 / GL 2*:

*Both hardeners can be mixed as required. The mixing ratio of 100: 30 resin to hardener remains unchanged.
