Universal™ Mold Release Agent is formulated especially for mold making and casting, and works well with most liquid rubber and liquid plastic products. It will release mold rubbers (such as polyurethanes and polysulfides) from properly prepared models. Sealing porous models (wood, plaster, concrete) or certain modeling clays (containing water or sulfur) with Smooth-On SuperSeal™ or other sealer may be necessary. Universal™ Mold Release is effective over a broad temperature range from 20° C to 260 °C.
If using silicone rubber, seal model surface with SuperSeal™ only. Do not use Universal™ Mold Release. Universal™ Mold Release also easily releases a variety of casting materials (epoxies, Smooth-On liquid plastics, etc.) from cured rubber molds. This product has a limited shelf life and should be used as soon as possible. Properly used, Universal™ Mold Release improves molding efficiency for a variety of casting applications and will actually lengthen the life of your production mold.
