  • Fluorinated ester compound additives for architectural coatings
    Patent number: 11518894
    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 ?30,000 Da; and where the fluorinated group Rf is independently a straight or branched perfluoroalkyl group of 2 to 20 carbon atoms, which is optionally interrupted by one or more CH2, CFH, ether oxygens —O—, or combinations thereof. The fluorinated ester compounds provide cleanability to the resulting coating made from the present composition.
