Abstract
One-part hydrophilic treatment compositions are provided which comprise (i) an aqueous solution of a sulfonato-organosilanol compound which has at least one sulfonato-organic substituent therein, and (ii) an abrasive material. These compositions are particularly useful in imparting hydrophilicity to siliceous surfaces.
Claims22
A one-part composition for imparting hydrophilicity to siliceous surfaces, said composition comprising
- (i) an aqueous solution of a sulfonato-organosilanol compound having at least one sulfonato-organic substituent, wherein the weight percentage of oxygen in said compound is at least about 30%, and the weight percentage of silicon in said compound is not greater than about 15%, said percentages being taken with reference to the water-free acid form of said compound;
- and
- (ii) an abrasive material.
