Epoxy system SR8100 / SD4771 for injection and infusion with ultra slow hardener
Each kilo includes 0.78 kg resin + 0.22 kg hardener
The SR8100 is a 2 component epoxy system specially formulated for resin transfer processes, such as injection and infusion. This system has a very low viscosity at ambient temperature. The different hardeners allow moulding of small to large parts, with fast demoulding times, high mechanical properties and good price. The cured system gives a temperature resistance up to 80 oC (Tg 1). The hardener SD4771 is designed for very thick fibers laminates.
