one. Features and main uses:
Winding 886 resin is an unsaturated polyester resin (modified) synthesized from phthalic anhydride, maleic anhydride and standard diols as main raw materials, and has been dissolved in styrene. With medium viscosity and medium reactivity, excellent mechanical properties, high elongation at break, especially suitable for winding process. FRP storage tanks and pipes made of glass fiber reinforced have excellent strength and toughness.
