TR-8200 Unsaturated Polyester Resin (modified)

2023-11-07

1. Features and main uses:

Tianrun TR-8200 is an unsaturated polyester resin (modified) with phthalic anhydride and standard diols as the main raw materials, which has been dissolved in styrene. Add white carbon black, dispersant, defoamer, metal cobalt and so on through high-speed dispersion and deep processing, with low viscosity, low reaction heat release temperature, good construction performance. It has good water resistance and excellent mechanical strength, and is suitable for manufacturing FRP fishing boats, yachts, lifeboats and other large molding products.
