Product Description
Product Name: HS-1520 Unsaturated Polyester Resin
1. Brief Introduction:
HS-1520 is a high-quality NPGl type unsaturated polyester resin specifically designed for SMC / BMC applications. It has high reactivity, low viscosity, good coloring and thickening properties.The surface of the product is flat, providing a high gloss finish that enhances the overall appearance of the final product. With excellent water resistance and heat resistance, high mechanical strength and good electrical performance, HS-1520 is widely used in electrical parts, industrial parts, sanitary parts, vehicle parts, and other fields where high-quality resin is required.
