<p>PURPOSE:To provide a surface-treating composition containing a specific fluorine-containing organic silicon compound or its partial hydrolytic condensation product and a catalyst for the condensation reaction, rapidly curing on the surfaces of substrates, and forming coating films having excellent water repellency, oil repellency and stain resistance. CONSTITUTION:(A) A fluorine-containing organic silicon compound of the formula (R<1> is monovalent hydrocarbon excluding alkenyl groups; R<2> is divalent organic group; alpha is 2, 3; m is an integer of 4-12) [e.g. 2-(perfluorooctyl) ethylsilane] or its partial hydrolytic condensation product, and (B) a catalytic amount of a condensation reaction catalyst (e.g. dibutyl tin diacetate) are homogeneously mixed in a solvent such as toluene to obtain the objective surface- treating composition rapidly curing on the surfaces of substrates and capable of forming coating films having excellent water repellency, oil repellency and stain resistance on the surfaces of the substrates.</p> |
