ABSTRACT:
A composition solution of resinous polymeric material with the composition including polyvinyl chloride or polyvinyl chloride-polyvinyl acetate copolymer, a saturated vegetable oil release agent typically coconut oil, and a plasticizer such as epoxidized vegetable oil. The composition solution is useful for forming a temporary protective coating on glass, metal, and non-porous plastic or painted surfaces unaffected by the solution solvents. Another use for the composition solution is to provide a plastic permanent protective coating for substances such as sheet rock and wood. This not only presents a barrier to insect invasion such as by termites into wood but also presents a smooth surface on wood forms used as cement forms that gives effective release from cement molded thereon. It is a sealer surface for sheet rock ideal for the mounting of wall paper which when removed may be peeled therefrom without tearing of the sheet rock surface paper.
