PURPOSE:To provide the titled treating agent capable of imparting excellent water repellency, etc., containing, as a main component, a product obtd. by mixing a perfluoroalkyl group-contg. organosilane with an organosilane having a monovalent org. group contg. a nitrogen atom, and partially co-hydrolyzing and condensing the mixture. CONSTITUTION:5-95mol% of a perfluoroalkyl group-contg. organosilane (A) of formula I (wherein R' is a 1-20C perfluoroalkyl group; R<2> is H, a 1-20C monovalent hydrocarbon group; R<3> is a bivalent org. group; Y is a hydroxyl group; X is 0-2), 0-90mol% of an organosilane (B) of formula II (wherein Y is 0-3) and 95-5mol% of an organosilane (C) having a monovalent org. group contg. a nitrogen atom and of formula III (wherein A is a monovalent org. group contg. at least one nitrogen atom; w is 1-2; z is 0-2) are mixed together. The mixture is partially co-hydrolyzed and condensed. The desired silicone treating agent can be obtd. by using the resulting product as a main component. |
