Abstract

A silicone emulsion comprises: (A) a silicone compound comprising an anchorage additive for enhancing the adhesion to a polymer film substrate; (B) at least one surfactant; and (C) water. The anchorage additive is the reaction product of (A1) a fluid polyorganosiloxane containing at least one alkenyl group and at least one silanol group with (A2) a hydrolysable silane containing at least one epoxide group. A water-based anchorage additive comprises the silicone emulsion. A silicone release coating composition comprises: (X1) the silicone emulsion; and (X2) at least one curable silicone composition, e.g. a water-based silicone release coating composition. The curable silicone release coating composition may be applied to a sheet-form substrate and cured to form a release-coated layer having good release property and improved rub-off resistance on the substrate.
