Claim Text:
1. A coating composition comprising a fluoropolymer composition and a coating base, wherein the fluoropolymer composition comprises a fluoropolymer dissolved in an organic solvent and further wherein the fluoropolymer comprises repeating units in any sequence of polymer units: wherein R X is an organic divalent linking group having from about 1 to about 20 carbon atoms, optionally containing a triazole, oxygen, nitrogen, or sulfur, or a combination thereof; Y is O; Z is a straight or branched alkyl group having from about 1 to about 4 carbon atoms, or halide; R R T is H, a straight, branched or cyclic alkyl group having from about 1 to about 10 carbon atoms, or halide; R each R i is 1 to about 200; and j is 0 to about 40; provided that 1) the repeating unit I, (R 2) repeating units I and II ((R 3) the total of all repeating units, I-VII plus any optional monomers equals 100% by weight of the polymer, wherein the subscripts a, c, and g are each independently from 5 to about 5,000, the subscripts b, e, and d are each independently from 0 to about 2,000, and subscript h is a positive integer up to 2,000; wherein the organic solvent is methyl isobutyl ketone, butyl acetate, tetrahydrofuran, acetone, isopropanol, ethyl acetate, methylene chloride, chloroform, carbon tetrachloride, cyclohexane, hexane, dioxane, hexafluoroisopropanol, or a mixture of two or more thereof, and wherein the coating base is selected from the group consisting of an alkyd coating, a Type I urethane coating, and an unsaturated polyester coating.
