TR-128APT Unsaturated polyester resins

一．Features and main purposes:
TR－128APT is a kind of unsaturated polyester resin synthesized with main materials of phthalic anhydride and standard diatomic alcohol, having dissolved in styrene.It is processed deeply at a high speed with addition of white carbon black, dispersing agent, de-foaming agent, metal cobalt, featuring low viscosity, low reactive exothermic temperature and good construction performance. It has good water resistance and mechanical strength, applicable for the manufacture of FRP fishing boats, yachts, lifeboats and other large molded products.

Specification of liquid resin：(25℃)：

Note: 25°C water bath, adding 1ml methyl ethyl ketone peroxide solution and 1ml colorless promoter T-8A solution into 100g resin
三．Casting matrix(typical valu)：

Note: (1) Casting matrix sample is made according to GB/T8237-2005; with temperature of 25°C, curing system: promoter RCA 1.0%, Curing agent M-50 1.5%.

(2) Post-curing treatment of casting matrix: room temperature×24 Hours+60°C×3 Hours+80°C×2 Hours;
