Electrophoretic coating process
Abstract
Abstract AN ORGANIC PHASE IS DISPERSED IN A ALKALINE AQUEOUS PHASE BY ADDITION OF POLAR DISPERSING AGENT MISCIBLE WITH ORGANIC PHASE. THESE EMULSIONS ARE USEFUL FOR COATING SELF-TERMINATING POLYMER FILMS ON CONDUCTING SUBSTRATES BY ELECTROPHORESIS. THE ELECTROCOATING PROCESS IS USEFUL FOR HIGH SPEED CONTINUOUS AND SEMI-CONTINUOUS OPERATIONS. THE ELECTROCOATING BATHS CAN BE REPLENISHED FROM A CONCENTRATE MATERIAL WITHOUT DISPROPORTIONATE BUILDUP OF BATH COMPONENTS. HIGH ELECTRICAL EFFICIENCY IS REALIZED IN WEIGHT OF FILM DEPOSITED PER UNIT OF CURRENT. EELECTRODEPOSITED FILMS PROVIDE EXCELLENT CORROSION RESISTANCE TO METAL SUBSTRATES WITH THIN FILMS OF ABOUT 10 TO 50 MICRONS THICKNESS. D R A W I N G
