Abstract:
A method of improving the storage stability and broadening the pH stability of an aqueous solution containing from about 0.001% to 5% by weight based on the total weight of the solution of a water soluble organosilane having the formula A3âˆ’xBxSiD, wherein A is â€”OH or a hydrolyzable group, B is an alkyl group of from 1 to 4 carbon atoms, x has a value of 0, 1 or 2, and D is a hydrocarbon group of from 1 to 4 carbon atoms, a fluoro substituted (otherwise substituted or unsubstituted) hydrocarbon group, phenyl, or a nonionic or cationic, substituted-hydrocarbon group containing at least one oxygen or nitrogen group or salts of such substituted-hydrocarbon groups, the method comprising:including within the solution from 0.001% to 5% by weight based on the total weight of the solution of a saccharide surface active agent selected from the group consisting of alkyl saccharides and alkenyl-saccharides, wherein quaternary ammonium compounds are not included within the solution, and wherein the saccharide surface active agent is effective to improve the storage stability of and to broaden the pH stability of the resulting solution.
