TR－968 Unsaturated polyester resins
Features and main purposes:
The spray resin is a kind of reactive flame-retardant unsaturated polyester resin synthesized with main materials of tetrabromophthalic anhydride and standard diatomic alcohol, having dissolved in styrene. Being pre-promoted, with medium viscosity and reactivity, after curing, it shows high mechanical properties and flame retardancy properties, extensively used in the spray process of various flame retardant FRP products
