ABSTRACT:
The present invention relates to a special coating composition based on components a) at least one hydrolysable fluoroalkylsilane of the formula (I) CF3(CF2)n(CH2)2Si(CH3)yX3-y, 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, wherein the 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.
