Product classification
TR-102 Gel coat
TR-102 Gel coat
Features and main purposes:
TR－102 is a kind of unsaturated polyester resin synthesized with main raw materials of isophthalic acid and neopentyl glycol, having dissolved in styrene with addition of imported fumed silica and other additives. It features excellent mechanical properties and weathering resistance, especially suitable for FRP products that have high demand for water resistance and weathering resistance, such as FRP boats, environmental protection fiberglass.
