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 70°F to 500°F.
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.
Universal™ Mold Release is available in aerosol spray or economical liquid form (one gallon, 5 gallon and 55 gallon drum.)
Aerosol USE ONLY WITH ADEQUATE VENTILATION:
Because no two applications are quite the same, a small test application to determine suitability is recommended if performance of this material is in question.
Painting A Finished Casting…
One method for applying paint to a casting is to remove release agent from casting with a solvent such as isopropyl alcohol or acetone. Next, apply one to two coats of auto body primer (available at most auto parts stores) and let dry. Finally, apply acrylic or similar base paint.
