ZC-8509 resin is mainly composed of m-benzene, maleic anhydride, neopentyl glycol and other standard diols The raw material of isophene-neopentyl glycol type unsaturated polyester resin, dissolved in styrene crosslinked monomer It has high viscosity and high reactivity.
ZC-8509 resin has high heat resistance, water resistance, weather resistance, and good mechanical properties and stability It can be obtained by adding 9282 low profile agent and 9262 low shrinkage agent Low shrinkage, zero shrinkage effect can reach class A surface. Suitable for high performance SMC/BMC system Products, used in bathroom, automobile, electrical appliances, construction and other fields.
