Oil and water repellent coating compositions

An oil and water repellent coating composition, comprising:

• (a) a resin, selected from the group consisting of colloidal inorganic-based siloxane resin, poly(dialkylsiloxane)monoorgano substituted silsesquioxane block copolymer, acrylic polymer and copolymer, ethylene-vinyl acetate latex and styrene-butadiene latex,
• (b) an aminoorganosilane of the general formula ##STR8## wherein R.sup.1 is selected from the group consisting of hydrogen, alkyl of one to four carbon atoms or ##STR9## R.sup.2 is an alkylene group of two to four carbon atoms, R.sup.3 is hydrogen or alkyl of one to four carbon atoms, R.sup.4 is an alkylene group of three to four carbon atoms, R.sup.5 and R.sup.6 are alkyl groups of one to four carbon atoms each, n is zero to four and m is zero or one;
• and
• (c) a perfluorinated organic compound of the general formula:
• R.sub.f Y
• wherein R.sub.f is a perfluoroalkyl group of four to 18 carbon atoms and Y is selected from the group consisting of --COOH, --COOR, wherein R is alkyl, alkoxyalkyl or hydroxyalkyl of one to eight carbon atoms;
• wherein the combined amount of the aminoorganosilane and the perfluorinated organic compound comprises between about 0.1 and about 10 percent by weight of said resin and the molar ratio of the perfluorinated organic compound to the sum of primary and secondary amine group(s) in the aminoorganosilane is fixed between about 0.33 and about 1.0.
