<p>A method for molding high water, high resiliency (HR) polyurethane foam articles is disclosed wherein a silicone mold release composition is used to treat the surfaces of a mold. The composition imparts release characteristics to the mold which last through multiple molding cycles allow recoating with said composition and allows the production of defect-free foam articles. The composition consists essentially of a high and a low molecular weight hydroxyl endblocked polydimethylsiloxane, a siloxane crosslinker having SiH functionality, a catalyst and an inert solvent.</p> |
