Release agent compositions for preventing adhesion and for facilitating separation of surfaces, such as patterns and core boxes from casting molds and cores, include: (a) styrene-diene block copolymers; (b) functionalized silicone; (c) a solvent; And optionally, either or both of (d) catalyst and (e) crosslinking agent. A method is also provided that facilitates separation of a workpiece from a substrate, comprising applying the release agent composition to the surface of the workpiece, substrate, or both. In one particular embodiment, the method improves the release of the mold or core from the pattern or core box.n n n Release Agent, Anti-stick Coating Composition |
