BCC Products BC 84 PVA Parting

BC 84 PVA Parting/Green is a water/alcohol solution of water soluble, film forming materials. It is particularly recommended as a parting layer for separation between polyester or epoxy resins and various mold surfaces. BC 84 is normally applied by spraying on the mold surface and dries at room temperature to form a smooth, very glossy film. It will not shrink and pull away from corners or curved surfaces. After drying of the resin the film parts easily from the mold and is readily dissolved from the molded parts with water. Porous mold must first be sealed with lacquer or similar coating. A good surface on plaster may be obtained with automobile type primer-sealers and lacquers. Plaster molds must first be thoroughly dried. Metal or plastic molds should be free of other parting agents, especially silicone types. Cleaning with fine steel wool or sandpaper will not affect the high gloss obtained with BC 84. Deep scratches or pits will fill with BC 84 solution and increase the drying time.Information provided by BCC Products, Inc.
