Product Description

Product Description

 

Product Name: HS-1520 Unsaturated Polyester Resin

1. Brief Introduction:HS-1520is a high-performance NPGl type unsaturated polyester resin designed specifically for SMC/BMC applications. Its exceptional characteristics include high reactivity,
low viscosity, excellent coloring, and superior thickening properties. The resin forms a flat surface witha high gloss finish, outstanding water resistance, and excellent heat resistance. It also boasts high mechanical strength and superbelectrical performance, making it ideal for use in electrical parts, industrial components, sanitary fixtures, vehicleparts, and many other applications.
