The present invention relates to a special coating composition based on components a) at least one hydrolysable fluoroalkylsilane of the formula (I) CF<SUB>3</SUB>(CF<SUB>2</SUB>)<SUB>n</SUB>(CH<SUB>2</SUB>)<SUB>2</SUB>Si(CH<SUB>3</SUB>)<SUB>y</SUB>X<SUB>3-y</SUB>, in which X is a group from the series chlorine, methoxy, ethoxy, isopropoxy, and n-propoxy and n is a number from the series 3, 4, 5, 6, 7, 8, and 9, and y is 0 or 1, b) HCl, c) water, d) isopropanol, and e) at least one further solvent and/or diluent from the series of the alcohols, glycols, glycol ethers, ethers, esters, ketones, and aliphatic and aromatic hydrocarbons, and on a silane component (a): water molar ratio of 1 : 4.5 to 1 : 9. The invention further relates to a process for preparing such a composition and also to its use for providing smooth, inorganic substrate surfaces with an abrasion-resistant and weathering-stable easy-to-clean coating. |
