TR-8200 Unsaturated polyester resins

Features and main purposes:
TR－8200 is a kind of unsaturated polyester resin synthesized with main materials of phthalic anhydride and standard diatomic alcohol, having dissolved in styrene.processed deeply at a high speed with the addition of white carbon black, dispersing agent, de-foaming agent and 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：

Note: gel time (varies with season) 25°C water bath, adding 2ml methyl ethyl ketone peroxide solution into the 100g resins. Test ambient temperature: 25°C
Specification of casting resin(typical value):

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;
