Product Description
Epoxy Resin For Winding Pipe is specially developed for pipe winding. It has low mix viscosity, g ood impregnation with fiber. The laminate has good tenacity, acid and alkali resistan ce, heat resistance, and mechanical performance. It's suitable for pipe winding and a ccessories, also can be used for infusion.
