Tianrun TR-638 is an unsaturated polyester resin (modified) with phthalic anhydride and standard diols as the main raw materials, which has been dissolved in styrene and added high activity flame retardant. With low viscosity and high reactivity, flame retardant, light resistance, water resistance, good weather resistance. It has high mechanical properties and hardness after curing. Especially suitable for flame retardant, transparent, light resistant, water resistant, weather resistant FRP products with high requirements.
