3311A/B is a low-viscous infusion resin system, consisting of an epoxy resin part 3311A and a modified amine hardener part 3311B. The resin system has excellent fiber wetting properties, which can be used for processing of glass, carbon and aramide fibers. Due to its excellent mechanical properties, this system is suitable for the production of components featuring high static and dynamic loadability.
Very low viscosity
Long pot life and very low exothermal peak
Good fiber wetting property
Excellent processing, thermal and mechanical properties
Specially designed for infusion processes (RTM; SCRIMP/VARI) which gel time >5hr such as rotor blades for wind turbines,boat and shipbuilding, sports equipment. It can also be used for winding process for LPG Cylinders which requires low temperature curing( 80oC).
