Hardener GL1 (30min) for resins L 0,75Kg
Hardener for epoxy resin L
The proven R&G L epoxy resin in combination with the GL 1 hardener offers an approval from Germanische Lloyd for the construction of boats and rotor blades for wind turbines.
Mixing ratio:
100: 30 parts by weight of resin: hardener
100: 35 parts by volume of resin: hardener
Processing time: approx. 30 minutes
Property:
Low viscosity (820 mPas at 25 ° C)
It completely polymerizes at 10 ° C
Glass transition temperature (Tg)> 80 ° C (post-curing at 70 ° C / 15 h)
Environmental polymerization does not cause fragility (at 20 ° C)
High static and dynamic resistance
This newly developed resin system is ideal for wetting glass, aramid and carbon fibers. It has an excellent price / performance ratio and is suitable for the following processing procedures:
Resin infusion (RI)
RTM (resin transfer molding)
Press molding
Vacuum molding
Filament winding
Hand rolling
The resin component itself is absolutely free of crystallization thanks to its bisphenol A / F base! The resin system is hardening to the environment and does not develop distinctive fragility even at hardening temperatures below 20 ° C. However, to improve the physical and chemical properties, we should perform a post-cure at least at 40 ° C for 15 hours .
Table mixing with epoxy resin processing times L + mixed GL 1/2 catalysts.
The mixing ratio of the 100: 30 resin with the hardener remains unchanged.
