Unsaturated polyvinyl chloride resin, modified epoxy resin
2023-11-07
1、 Features and main uses:
Tianrun TR-1603 is an unsaturated polyester resin (modified) mainly composed of phthalic anhydride and standard diols, which is soluble in styrene. It has low viscosity and high reactivity, excellent flame retardancy, light resistance, water resistance, and weather resistance. After curing, it has high mechanical properties and hardness. Especially suitable for FRP products with high requirements for transparency, light resistance, water resistance, and weather resistance.
