Patent ID: 7704561

Claim:
A method of treating an inorganic surface comprising applying to the surface an aqueous solution consisting essentially of at least one ionic organosilicon compound selected from the formula: wherein: Y is RO where R is an alkyl radical of one to four carbon atoms, (CH 2 CH 2 O) n H where n has a value of one through ten, (CH 3 OCH 2 CH 2 ), or (CH 3 CH 2 OCH 2 CH 2 ); a has a value of zero, one and two; R′ is a methyl or ethyl radical; R″ is an alkylene group one to four carbon atoms; R′″, R″″ and R v are alkyl groups containing one to twenty two carbon atoms, wherein at least one such group is larger than eight carbon atoms, —CH 2 C 6 H 5 , —CH 2 CH 2 OH, —CH 2 OH, and —(CH 2 ) x NHC(O)R vi wherein x has a value of from two to ten and R vi is a perfluoroalkyl radical having one to twelve carbon atoms; and X is chloride, bromide, fluoride, iodide, acetate or tosylate; such that said surface exhibits a water exclusion percentage from about 80 to about 100% wherein the inorganic surface has functional groups that will bond with silanols.
