Product classification
TR-Gangshi 1＃ Unsaturated polyester resins
TR-Gangshi 1＃ Unsaturated polyester resins
Features and main purposes:
TR－Gangshi 1＃ is a kind of unsaturated polyester resin synthesized with main materials of phthalic anhydride and standard diatomic alcohol, having dissolved in styrene,With medium viscosity and high reactivity, it is characterized by good performance in light-resistance, water-resistance and weathering-resistance. After curing, it shows high mechanical properties and hardness, especially applicable for FRP products that have high demand for transparence, light-resistance, water-resistance and weathering-resistance.
