HS-1500 Unsaturated Polyester Resin
Principal Properties & Application:HS-1500 is an unsaturated polyester resin used for SMC/BMC applications. It is made from maleic anhydride and standard diols as the main raw materials. This resin offers high reactivity, medium viscosity, and excellent thickening stability. When combined with low shrinkage agents such as HS-9892, HS-9812, and HS-9819, it produces high surface quality SMC/BMC products.
