The present invention relates to a composition of (a) a coating base selected from a water dispersed coating, an epoxy polymer coating, an alkyd coating, a type I urethane coating or an unsaturated polyester coating; and (b) a fluorinated ester compound having a plurality of fluoroalkylthioether groups, the number average molecular weight of the fluorinated ester compound being <30,000 Da; and wherein the fluorinated group Rf is, independently, a linear or branched perfluoroalkyl group of 2 to 20 carbon atoms, which is optionally interrupted by one or more CH2, CFH, ether-O- ether-oxygen or corresponding combinations. The fluorinated ester compounds impart a resultant cleanability to the resulting coating made from the present composition. |
