Low viscosity, medium reactivity, promoted, general purpose, unsaturated polyester resin. This type of resin resulted from dissolving of Ortho phthalic with styrene monomer under very special conditions.
is mainly recommended for Glass fiber laminates for general purpose applications such as pipes industry besides the manufacturing of tanks and containers for fuels and draining hole covers, due to its excellent chemical resistance.
It is a kind of pre-accelerated terephthalic unsaturated polyester resin with medium viscosity and high reactivity. It has the characteristics of high mechanical strength, high toughness, high heat deflection temperature, excellent thermal and water resistance, corrosion resistance, and good fiberglass wetting.

Unsaturated Polyester Resin (UPR)
Curing properties are those obtained using 2% Cobalt Octoate (1% cobalt metal) & 2% MEK Peroxide (M50) in 100 grams of resin previously stabilized at 25°C.
Storage: In Drums/ IBC’s: Product should be kept in temperature below 25°C. Direct heat sources such as sun light must be avoided as it decreases product’s shelf life. drums or tanks should be kept well sealed to avoid moisture or monomer loss.
Annual Production: 9,000 tons.
