P.V.A. (Polyvinyl Alcohol) is still the standard barrier coating material for the fiberglass reinforced plastics industry. P.V.A. is also used as a mold barrier when casting polyester, epoxy or polyurethane resins and foams into most types of rigid molds. Normally used in conjunction with a top coating of paste wax, the film may be removed with water from the cast part once the part has been removed from the mold.
