2023-11-07
1. Features and main uses:
TR-N3250PT is an unsaturated polyester resin (modified) with phthalic anhydride and standard diols as the main raw materials, which has been dissolved in styrene. It has moderate reactivity. It has the characteristics of medium viscosity, high thixotropy and fast post-curing. Especially suitable for model production and high performance FRP products.
