          N3250PT unsaturated polyester resin (modified)

          2023-11-14

          1、 Features and main uses:

          TR N3250PT is an unsaturated polyester resin (modified) mainly composed of phthalic anhydride and standard diols, which has been dissolved in styrene. Has moderate reactivity. It has the characteristics of medium viscosity, high thixotropy, and fast post curing. Especially suitable for model making and high-performance FRP products.
