Construction Material Unsaturated Polyester Resin

Unsaturated Polyester Resin

1, DCPD191 resin is a DCPD type unsaturated polyester resin with medium viscosity and reactivity. This type of resin has excellent mechanical properties, especially outstanding waterproof property. This resin is suitable to make cooling tower, water tank, and other FRP products.
