ABSTRACT:
A corrosion inhibiting paint composition comprises from about 1 to 20 parts by weight of a corrosion inhibiting additive mixture comprising 1 to 25 parts by weight of an organic sulfonic acid in a mixture of 75 to 99 parts by weight of butyrolactone; from about 10 to 99 parts by weight of film forming polymer; and from about 0 to 89 parts by weight of a liquid medium selected from the group consisting of water, organic solvents for the film forming polymer and mixtures thereof. Another corrosion inhibiting paint composition comprises from about 1 to 20 parts by weight of a corrosion inhibiting additive mixture comprising 1 to 25 parts by weight of an organic sulfonic acid in a mixture of 75 to 99 parts by weight of butyrolactone; from about 10 to 98.5 parts by weight of film forming polymer; from about 0.5 to 20 parts of an intrinsically conductive polymer; and from about 0 to 89 parts of liquid medium selected from the group consisting of water and organic solvents for the film forming polymer and mixtures thereof. Metal substrates containing a coating composition comprise an organic film forming matrix and an additive mixture comprising organic sulfonic acid and butyrolactone. A method for imparting corrosion resistance to metal substrates comprises providing a layer of a coating composition on at least one surface of the substrate, formed from an organic film forming matrix and an additive mixture comprising an organic sulfonic acid and butyrolactone.
