        TR 638 unsaturated polyester resin (modified)

        2023-11-14

        1、 Features and main uses:

        Tianrun TR-638 is an unsaturated polyester resin (modified) mainly composed of phthalic anhydride and standard diols. It has been dissolved in styrene and added with highly active flame retardants. 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 flame retardancy, transparency, light resistance, water resistance, and weather resistance.
