PVA Mold Release Agent PVA Partall #10 is a polyvinyl alcohol (PVA) water/alcohol solution of water-soluble, film-forming materials for mold release applications. This parting film is particularly recommended as a parting agent for separation between polyester or epoxy resins and various mold surfaces. It is not recommended for use with resins containing water or giving off water during the cure. PVA will not shrink and pull away from corners or curved surfaces. After resin has dried, the film separates easily from the mold and is readily dissolved from the molded parts with water. An occasional coating of Partall Paste #2 is required on most mold surfaces before application of Partall Film #10. May be applied over gel coat as a surface cure agent.
