Abstract
A silicone release coating emulsion includes a reactive crosslinkable silicone, a catalyst and a high molecular weight, water soluble or water dispersible polymeric thickening agent such as polyethylene oxide. The polymeric thickening agent has a molecular weight greater than about 100,000 g/mole Mw. The silicone release emulsion is applied as a coating to a substrate, and particularly paper, and cured to form a release coating for pressure sensitive adhesives. The silicone emulsion exhibits improved holdout of the silicone from the substrate.
