Abstract
Aqueous emulsions of curable silicone compositions provide cured coatings having improved gloss and/or water-repellancy and/or adhesive release if formulated to contain polyvinylachohol having a degree of hydrolysis of 90 mol % or more. The extent of improvement is directly related to the degree of hydrolysis of the PVA. PVA having an average degree of hydrolysis of from 94 to 99 mol % is particularly effective for improving these properties of cured coatings. Conveniently, a mixture of two or more commercially available PVAs having different degrees of hydrolysis can be used to arrive at a PVA having a desired degree of hydrolysis.
