Tianrun TR-1070M/W/S is an unsaturated polyester resin (modified) synthesized from phthalic anhydride and diols, which is soluble in styrene. Made by adding white carbon black, dispersant, defoamer, metal cobalt, etc. through high-speed dispersion and deep processing, it has medium viscosity, high thixotropy, no flow in the vertical plane, and excellent mechanical properties. Fiberglass products suitable for hand layup/spray molding processes.
