Hydrolyzable silane emulsions and method for preparing the same

A process for preparing an oil-in-water emulsion comprising at least one hydrolyzable silane, at least one emulsifier, and water, comprising the steps of:

• I) dispersing at least one emulsifier in water at a weight ratio of 1.5:1.0 to about 1.0:4.0;
• II) preparing an oil concentrate by mixing said emulsifier and water blend with at least one hydrolyzable silane having the general formula:
• R1aR2bSi(OR3)[4−a−b]4−a−b
• wherein
• R1 is a hetero atom substituted hydrocarbon group;
• R2 is independently an unsubstituted hydrocarbon group;
• R3 is an alkyl, alkoxyalkyl, aryl or aralkyl radical having from 2 to 10 carbon atoms;
• and
• a is 0 to 3, b is 0 to 2;
• with the proviso that a+b=1,2 or 3;
• and each R group is cyclic, branched or linear;
• and
• such that said oil concentrate comprises about 1 part to about 28 parts of said emulsifier and about 1 part to about 55 parts water, per 100 parts of said at least one hydrolyzable silane and
• III) slowly adding water to said oil concentrate until inversion of said oil concentrate occurs.
