Abstract
A heat curable aqueous emulsion coating composition is disclosed which is adapted to deposit a release coating which stratifies to allow less silicone to effectively coat a given surface area. This emulsion comprises water containing: (1) a fatty acid or fatty alcohol-containing hydroxy-functional polyester having a hydroxy value of at least about 40 and which is a free flowing liquid at room temperature; (2) a cross-linking agent for said hydroxy resin; and (3) at least one silicone reactive with said hydroxy-functional resin and/or said cross-linking agent to provide a release function. The hydroxy-functional polyester and the cross-linking agent serve to emulsify the silicones in the aqueous phase of the emulsion.
