          2023-11-14

          1、 Features and main uses:

          Tianrun TR-885IN is an unsaturated polyester resin (modified) synthesized from isophthalic anhydride and neopentyl glycol as the main raw materials, which has been dissolved in styrene. It has moderate viscosity and reactivity, high water resistance, and high hardness. Especially suitable for imitation granite/marble, with a hard surface material.
