Product Description

Product Description

 

Product Name: HS-1520 Unsaturated Polyester Resin

1. Brief Introduction:HS-1520 is a cutting-edge NPGl type unsaturated polyester resin specially designed for SMC and BMC applications. Boasting high reactivity,
low viscosity, and superior coloring and thickening properties, this resin ensures a flat surface with exceptionally high gloss. It offers outstanding water and heat resistance, remarkable mechanical strength, and excellent electrical performance. Ideal for use in electrical parts, industrial components, sanitary ware, and vehicle parts, as well as various other fields.
