Product classification
TR－86A Unsaturated polyester resins
TR－86A Unsaturated polyester resins
Features and main purposes:
TR－86A is a kind of unsaturated polyester resin synthesized with main materials of phthalic acid, propylene glycol and a small amount of neopentyl glycol, having dissolved in styrene. It features low viscosity, moderate reactivity and excellent mechanical properties, applicable for injection molding crafts, especially for the production of artificial stone products.featuring excellent strength, toughness and water resistance, weathering resistance.
