Abstract:
A storage stable aqueous solution comprising:from 0.001% to 5% by weight of the total amount of the aqueous solution of a water soluble organosilane;from 0.001% to 5% by weight of the total amount of the aqueous solution of a saccharide surface active agent; andfrom 0.001% to 2% by weight of the total amount of the aqueous solution of a non-ionic surfactant other than a saccharide,wherein the water soluble organosilane has the formula A.sub.3-x B.sub.x SiD, whereA is selected from the group consisting of --X, --OR.sup.1, --OR.sup.2A OR.sup.1, --N(R.sup.1).sub.2, --OOCCH.sub.3, --HNOCCH.sub.3, and --H, where X is a halide, R.sup.1 is R.sup.2 or hydrogen, R.sup.2 is an alkyl group of 1 to 4 carbon atoms, and R.sup.2A is a divalent saturated hydrocarbon group of from 1 to 4 carbon atoms,B is an alkyl group of from 1 to 4 carbon atoms,x has a value of 0, 1 or 2, andD 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,wherein the saccharide surface active agent has the formula: R.sub.10 --O--(R.sub.12 O).sub.t --(G).sub.p whereR.sub.10 is a linear or branched alkyl, alkenyl or alkyl-phenyl grout having 6-18 carbon atoms,is an alkylene group having 2-4 carbon atoms,G is a reduced saccharide residue having 5-6 carbon atoms,t is 0-10, andp is 1-10, andwherein quaternary ammonium compounds are not included within the aqueous solution.
