ABSTRACT:
A method of preparing an organo-alkoxy substituted silicone resin including the steps of reacting an organo-silicone resin containing hydroxy terminated functional groups with an alkoxy silane in the presence of catalytic amounts of a titanate compound and incubating the mixture to derive the organo-alkoxy substituted silicone product and an hydroxylated biproduct. The organo-alkoxy substituted silicone product may be reacted with a hydroxy functional fluid in the presence of catalytic amounts of a titanate compound to derive a non-transferable, semipermanent release agent.
