Abstract
The present invention provides a fluoropolymer coating composition which is capable of coating thick and forming a coating film being excellent in abrasion resistance, corrosion resistance and non-sticking property, and provides a coated article obtained by coating the above-mentioned composition as a top coat. The fluoropolymer coating composition comprises fine particles of a fluoropolymer, 0.1 to 300% by weight of a polyether type resin on the basis of a weight of the above-mentioned fine particles and a liquid carrier, and the polyether type resin is a resin represented by the formula (I): EQU R.sup.1 --Y.sup.1 --(A--B)--R.sup.1 (I) wherein R.sup.1 is hydrogen or an alkyl, Y.sup.1 is ether, ester, urethane or thionyl, A is alkylene oxide residual group having at least 3 carbon atoms (A molecular weight of an alkylene oxide moiety obtained by polymerization is 1.times.10.sup.3 to 1.times.10.sup.4), B is urethane, thionyl or phosphoric acid residual group (in the parenthesis is represented a residual group obtained through alternating copolymerization), and a temperature where the above-mentioned resin is decomposed and vaporized is in the range up to a decomposition temperature …
