Universal Mold Release
Universal Mold Release® is formulated especially for mould making and casting, and works well with most liquid rubber and liquid plastic products. It will release mould rubbers (such as polyurethanes and polysulfides) from properly prepared models. Sealing porous models (wood, plaster, concrete) or certain modelling clays (containing water or sulphur) with Smooth-On SuperSeal® or other sealer may be necessary. If using silicone rubber, seal model surface with SuperSeal® only. Do not use UMR.UMR also easily releases a variety of casting materials (epoxies, Smooth-On liquid plastics, etc.) from cured rubber moulds. Properly used, Universal Mold Release improves moulding efficiency for a variety of casting applications and will actually lengthen the life of your production mould.
