Principal Properties & Application：
HS-1010B is a kind of unsaturated polyester resin which is used in the production of FRP lighting plate. The FRP made of it has good wettability, mechanical strength , transparency, and anti-aging performance when exposed to the ultraviolet. HS-1010B is suitable for both machine and hand lay-up method.
