Unsaturated Polyester Resins

Unsaturated polyester resin series, such as SWANCOR 961, SWANCOR 963 and SWANCOR 9601, are all p-benzene type unsaturated polyester resins. These resins have excellent mechanical properties, water resistance and chemical resistance. Their toughness is better than m-phenylene resin. They are widely used in various molding processes, such as hand paste, winding, casting, etc., and are mostly used in some non-extreme corrosive environments. This kind of products can also be prepared into pre promoted type such as SWANCOR 961-P and pre promoted anti sag flow type such as SWANCOR 961-TP to meet different process requirements.

Among them, SWANCOR 961 and SWANCOR 963 are commonly used for structural layer, water pipeline and wastewater storage tank; SWANCOR 9601 is a UP resin certified for double wall fuel tank, which is more suitable for preparing underground fuel tank and double wall fuel tank.
