Coating composition of a mixture of a vinyl chloride-acetate copolymer with a mixture of acrylic resins and one-half second cellulose acetate butyrate
Abstract
Abstract A COATING COMPOSITION FOR USE ON POROUS AND NONPOROUS SUBSTRATES IS COMPOSED OF A VINYL CHLORIDE-ACETATE COPOLYMER, ACRYLIC RESINS, PLASTICIZERS, STABILIZERS, ANTIOXIDANTS AND PIGMENTS OR DYES IN SOLUTION IN A SOLVENT. THE ACRYLIC RESINS ARE METHYL METHACRYLATE ACIDING COPOLYMER OF MEDIUM MOLECULAR WEIGHT AND AN ACIDIC NUMBER OF FROM 12 TO 15 IN ABOUT EQUAL PARTS WITH N-BUTYL METHACRYLATE. THE PLASTICIZERS ARE POLYMERIZED CASTOR OIL AND MODIFIED METHYL ACETYL RICINOLATE IN A RATIO OF ABOUT 1.3 PARTS BY WEIGHT TO 1 PART BY WEIGHT OF THE VINYL CHLORIDE COPOLYMER. THE SOLVENT CONTENT IS VARIED TO SUIT THE PARTICULAR METHOD OF COATING. IN MOST APPLICATIONS, COATING ON VINYLS AND LEATHER, FOR EXAMPLE, ONE-HALF SECOND CELLULOSE ACETATE BUTYRATE IS USED TO ABLOCK PLASTICIZER MIGRATION TO THE SURFACE OF THE COATING OF FILM.
