Partially fluorinated ester compound additives for architectural coatings

Abstract:

The present invention is a composition comprising (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 represented by Formula (I): ##STR00001## where A is --OH, a C.sub.1-C.sub.18 alkyl, --CH.sub.2COOH, --CH.sub.2OH, or (CH.sub.2CH.sub.2O).sub.a(CH.sub.2CH(CH.sub.3)O).sub.bH; a and b are 0 to 3; s is 0 to 2; Y is a linear or branched alkylene organic group having r+s+t substitutions; x is 0 or 1; Q is --C(O)O-- or --OC(O)--; Z is --(CH.sub.2).sub.yS-- or --(CH.sub.2CH.sub.2O).sub.m(CH.sub.2CH(CH.sub.3)O).sub.n--; y is 2 to 6; m and n are 0 to 6; R.sub.f is a straight or branched perfluoroalkyl group of 2 to 20 carbon atoms; R.sup.7 is a straight or branched C.sub.4-C.sub.30 alkyl; r is 1 to 4; and t is 1 to 5, such that r+s+t is 2 to 6.
