Epoxy system SR8100 / SD8822 for injection and infusion with slow hardener
Each kilo includes 0.76 kg resin + 0.24 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 two different hardeners (SD8822 and SD8824) 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).
