Partall Film Coverall - Purple (1 Quart)

PARTALL® Coverall Film is a water-based polyvinyl alcohol (PVA) coating comprised of solvent-resistant, film-forming materials. Once dry, the PVA film is resistant to solvents in the resin system used to make composites parts but is soluble in water. It is particularly recommended as a parting agent for separation between polyester, vinylester, or epoxy resins and various mold surfaces but may be used with most thermoset resins. PARTALL® Coverall Film is not recommended for use with mold substrates or resins (e.g., phenolics) containing water or giving off water during cure or with automotive finishes.

PARTALL® Coverall Film parts easily from mold surface and is readily dissolved from molded parts and spray equipment with water. For most composite casting processes, PARTALL® Coverall Film is used over wax such as PARTALL® Paste #2 or other mold release agents and renewed for each part casting
