epoxy system sicomin sr1124 sd4771, epoxy resin for impregnation, auto extinguishing epoxy resin, epoxy resin for laminating
(Set of 2 components resin + hardener)
Fire resistant epoxy laminating system SR1124 / SD4771 with ultra slow hardener
Each kilo includes 0.81 kg resin + 0.19 kg hardener
Epoxy system SR1124 / SD4771 offers very low viscosity with excellent wetting-out properties, making it suitable for hand laminating applications. It is a low-density, fire-retardant system with an intumescent, halogen-free formulation. The system also provides low smoke opacity and toxicity and meets stringent fire protection standards required in construction and transportation applications.
