Electrodeposition of coating materials comprising particulate elastomers
Abstract
Abstract ELECTRODEPOSITABLE COATING MATERIALS ARE PROVIDED WHICH COMPRISE PARTICULATE ELASTOMERIC MATERIALS. THESE PARTICULATE ELASTOMERS MAY BE (1) MECHANICALLY MIXED WITH AN ELECTRODEPOSITABLE CARRIER RESIN AND ELECTRODEPOSITED THEREWITH WITHOUT CHEMICAL REACTION THEREWITH BEFORE A AFTER ELECTRODEPOSITION, (2) MECHANICALLY MIXED WITH A CONVENTIONAL ELECTRODEPOSITION CARRIER RESIN AND CHEMICALLY REACTED WITH THE RESIN DURING CURING, (3) CHEMICALLY REACTED WITH AN ELECTRODEPOSITION CARRIER RESIN PRIOR TO ITS ELECTRODEPOSITION, (4) CHEMICALLY REACTED WITH MONOMERS OR LOW MOLECULAR WEIGHT PREPOLYMERS WHICH PROVIDE THE RESULTANT REACTION PRODUCT WITH IONIZABLE SURFACE FUNCTIONALLY TO IMPART POLYELECTROLYTE BEHAVIOR TO THE MATERIAL WHEN DISPERSED IN A SUITABLE AQUEOUS MEDIUM, (5) OR PROVIDED DIRECTLY WITH SUCH IONIZABLE SURFACE FUNCTIONALITY. THIS INVENTION HAS APPLICATION IN BOTH ANODIC AND CATHODIC DEPOSITION. THE ELECTRODEPOSITABLE MATERIALS CAN BE DEVISED FOR CONVENTIONAL HEAT CURING, AIR DRYING, OR CURING BY IONIZING RADIATION, E.G. EXPOSURE TO AN ELECTRON BEAM. IN ONE EMBODIMENT, THE PARTICULATE ELASTOMERS HAVE AN OUTER SHELL OF A GLASS-LIKE ORGANIC POLYMER. IN ONE EMBODIMENT, THE ELECTRODEPOSITED MATERIAL HAS ALPHA-BETA OLEFINIC UNSATURATION.
