Unsaturated polyvinyl chloride resin, modified epoxy resin
2023-11-07
1. Features and main uses:
Tianrun TR-602U is an unsaturated polyester resin (modified) with phthalic anhydride and standard diols as the main raw materials, which has been dissolved in styrene. It has medium viscosity and high reactivity, excellent light resistance, water resistance and weather resistance. It has high mechanical properties and hardness after curing. It is especially suitable for FRP products with high requirements of transparency, light resistance, water resistance and weather resistance.
