Product classification
TR-118 Unsaturated polyester resins
TR-118 Unsaturated polyester resins
Features and main purposes:
TR－118 is a kind of unsaturated polyester resin synthesized with main raw material of phthalic anhydride, standard diatomic alcohol and neopentyl glycol, having dissolved in styrene，featuring low viscosity, high reactivity，Excellent mechanical properties，Due to the characteristics of light color, high transparency, low shrinkage and exothermic peak,it is applicable for the production of pearlescent plate and artificial stones，with features of excellent strength, toughness, water-resistance and weathering-resistance.
