HS-1180SSK
HUAKE
Principal Properties & Application：
HS-1180SSK is an unsaturated polyester resin for SMC/BMC, primarily made from maleic anhydride and standard glycols. It features high reactivity, relatively high viscosity, and good thickening properties. When used in conjunction with low-shrinkage additives such as HS-9817 and HS-9819A, it can produce SMC/BMC products with A-grade surface quality. It is suitable for A-grade surface automotive parts, electrical coil encapsulation, and other applications.
