2023-11-13
1、 Features and main uses:
Tianrun TR-885 is an unsaturated polyester resin (modified) synthesized from phthalic anhydride and standard diols as the main raw materials, which has been dissolved in styrene. It has low viscosity, moderate reactivity, and high hardness. Especially suitable for imitating granite/marble and handicrafts, with excellent strength, toughness, water resistance, and weather resistance.
