FLUORINATED ESTER COMPOUND ADDITIVES FOR ARCHITECTURAL COATINGS

Abstract:

The present invention is 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 fluoroalkyl thioether groups, wherein the number average molecular weight of the fluorinated ester compound is .ltoreq.30,000 Da; and where the fluorinated group R.sub.f is independently a straight or branched perfluoroalkyl group of 2 to 20 carbon atoms, which is optionally interrupted by one or more CH.sub.2, CFH, ether oxygens --O--, or combinations thereof. The fluorinated ester compounds provide cleanability to the resulting coating made from the present composition.
