Rust Preventive Agent
T747 is an alkenyl butanedioic acid semi-fat rust preventive agent, which is obtained by the reaction between olefin and maleic anhydride, and then fatliquorized. Its antirust property is comparable with that of T746, but with lower acid value and good fluidity, it is used to make antirust turbine oils, machine tool oils, hydraulic oils, antirust greases and antirust agents for fuel detergents. It is especially suitable for modulating various kinds of antirust oils with lower acid value.
