Abstract:
A coating composition liquid at room temperature, said coating composition containing one or more liquid soil-reducing and/or friction-reducing compositions consisting of silicon resins and optionally one or more organic (co)polymers in admixture with functional silanes, said admixture hydrolyzed in organic solvents, said soil-reducing and/or friction-reducing compositions consisting of,(1) a polymer component selected from the group consisting of (A) a silicon resin mixture of (A1) polyorganosiloxanes comprising units (T units) of the formula (R1Siâ€”O3/2) and optionally, units (M units) of the formula (R3Siâ€”O1/2), and (A2) polyorganosiloxanes comprising units (Q units) of the formula (Siâ€”O4/2) and, optionally, units (M units) of the formula (R3Siâ€”O1/2), â€ƒwherein R is identical or different and is a non-halogenated aliphatic hydrocarbon radical having 1 to 18 carbon atom(s) per radical or a halogenated hydrocarbon radical selected from the group consisting of the 3,3,3-trifluoro-n-propyl radical, the 2,2,2,2â€²,2â€²,2â€²-hexafluoroisopropyl radical, and the heptafluoro isopropyl radical, or OR1, where R1 is identical or different and represents hydrogen or a monovalent, unsubstituted or substituted hydrocarbon radical having 1 to 8 carbon atom(s), with the proviso that A1 and A2 contain from 0.01% to 3.0% by weight, of Si-bonded radicals OR1, â€ƒand optionally one or more organic (co)polymer of (B) through (J) (B) vinyl chloride-hydroxypropyl acrylate copolymers, (C) vinyl acetate-ethylene copolymer, (D) polyvinyl chloride, (E) polyamide, (F) polyester, (G) acrylate-polyester copolymers, (H) polyamide-polyester copolymers, (I) vinyl acetate-polyester copolymer, and (J) monomeric (meth)acrylates, with the proviso that they are copolymerized with Si-bonded (meth)acrylate group-containing silanes, â€ƒwith (2) a silane of the formula R3xSi(OR2)4-x, â€ƒwhere R2 is a monovalent, unsubstituted or substituted hydrocarbon radical, R3 is a monovalent, substituted or unsubstituted alkyl, alkenyl, or cycloalkyl radical, x represents 0 or 1, â€ƒand containing (3) from about 10% to about 90% by weight based on the total weight of the composition of one or more organic solvents, (4) optionally, one or more catalysts, and (5) optionally, water.
