Partall® One-Coat is a water-based polyvinyl alcohol (PVA - Parting Film) coating made up of solvent-resistant, film-forming materials. It contains 2-3 times the solids content of standard PVA coatings, giving it a thick viscosity that builds quickly. It is commonly used as parting film between polyester, vinyl ester or epoxy resins and various mold surfaces or as a release barrier when making rigid support shells for elastomeric rubber molds. It is not recommended for use with molds or resins (e.g., phenolics) containing water or giving off water during cure.
Partall® One-Coat releases easily from mold or part surface or application equipment by peeling off in a continuous skin or by dissolving with water and scrubbing with a soft bristle brush or sponge.
