Rust and Corrosion Inhibitors


T747 is alkenyl succinic acid half ester anti-rust additive. It is manufactured from olefin reacted with Maleic anhydride and then conducted esterification. The anti-rust capability is equal to WX746 but it has lower TAN and easy to flow. It is used to blend anti-rust turbine oil, machine tool oil, anti-rust grease and as anti-rust component in fuel additive package. Especially for make various anti-rust lube oils with low TAN.
