    TR-118 unsaturated polyester resin (modified)

    2023-11-13

    1、 Features and main uses:

    Tianrun TR-118 is an unsaturated polyester resin (modified) synthesized from phthalic anhydride, standard diols, and neopentyl glycol as the main raw materials. It is soluble in styrene and has low viscosity and high reactivity. It has excellent mechanical properties, light color, high transparency, small shrinkage, and low exothermic peaks. Suitable for making pearlescent boards and artificial stone products, with excellent strength, toughness, water resistance, and weather resistance.
