<p>An improved molding process is provided which comprises treating a mold surface with certain curable silicone compositions to improve the release of a molded article from the mold. The curable silicone release composition is obtained by mixing a vinyl-endblocked polydiorganosiloxane, a xylene-soluble vinyl-containing resinous polysiloxane, a methylhydrogenpolysiloxane crosslinking agent and a hydrosilylation catalyst. The curable silicone release composition is easily applied to and rapidly cured onto the mold surface and, when cured, provides many easy releases of molded articles such as high resiliency polyurethane foam cushions, polyurethane elastomeric shoe soles and polyester boat hulls.</p> |
