一．Features and main uses:
TRT162D is a modified unsaturated polyester resin synthesized from isophthalic acid, maleic anhydride, and standard diols, dissolved in styrene. It exhibits medium viscosity and high reactivity. Pultruded products made with it exhibit high strength, toughness, and excellent heat resistance. It is suitable for pultrusion molding and is ideal for the production of 4G/5G radomes and other hollow pultruded products.
