        TR-968 spray unsaturated polyester resin (modified)

        2023-11-14

        1、 Features and main uses:

        TR-968 spray resin is a reactive flame retardant unsaturated polyester resin (modified) mainly composed of tetrabromophthalic anhydride and standard binary alcohol, which has been dissolved in styrene. Pre promoted, with moderate viscosity and reactivity, and excellent mechanical and flame retardant properties after curing. Widely applicable to the spraying process of various flame-retardant fiberglass products
