          TR-886 Unsaturated Polyester Resin (modified)

          2023-11-07

          1. Features and main uses:

          Tianrun TR-886 is an unsaturated polyester resin (modified) synthesized from phthalic anhydride, maleic anhydride and standard diols, which has been dissolved in styrene. With medium viscosity and medium reactivity, excellent mechanical properties, high fracture elongation, especially suitable for winding process. FRP storage tanks and pipes reinforced with glass fiber have excellent strength and toughness.
