一．Features and main uses:
TR1603 is a modified unsaturated polyester resin made primarily from phthalic anhydride and standard diols, soluble in styrene. It offers low viscosity and high reactivity, and is flame-retardant, light-resistant, water-resistant, and weather-resistant. After curing, it exhibits high mechanical properties and hardness. It is particularly suitable for FRP products requiring high transparency, light-resistant, water-resistant, and weather-resistant properties.
