SR8500 / KTA311 epoxy system for cold (or hot) preimpregnation
Each kilo includes 0.83 kg resin + 0.17 kg hardener
SR8500 / KTA311 is a 2 component, slow reactivity, solvent and reactive diluent free matrix system, designed for manual, (hand,) in-house fabric preimpregnation. Before mixing, the 2 components have a storage life of at least 1 year. After mixing and impregnation, the resulting preimpregnated fabric develops the desired tack at room temperature, and may be placed in a freezer. The out (of the freezer) life of this prepreg is at least 1 month. Consequently, this system is a versatile, cost effective solution that helps small production facilities to reduce their stock, and avoid keeping large quantities of various kinds of prepregs in the freezer. Curing temperature range is from 80 to 150 oC.
Applications:
Fabric preimpregnation by hand or machine, filament winding and adhesives. Particularly useful also for very large parts and hot press moulding.
