Abstract: ELECTROPHORETIC COATINGS ARE FORMED SELECTIVELY UPON SURFACES RECEPTIVE TO COATING. THE COATING SUSPENSION IS EXTRUDED IN A SMALL VISCOUS MASS AT THE SELECTED SURFACE SITE AND A COATING DEPOSIT IS FORMED THE THE MASS BY ELECTROPHORESIS. AND HAND TOOL DEVISED FOR THIS PURPOSE INCLUDES A RESILIENTLY DEFORMABLE HAND MANIPULATABLE VESSEL ASSEMBLY HAVING A CAPPED FILLER OPENING FOR RECEIVING SUPPLIES OF THE COATING SUSPENSION FLUID AND A DISPENSING DUCT FOR EXTRUDING THE SUSPENSION. THE DUCT INCLUDES A FLEXIBLE INSULATED NOZZLE ELEMENT CONNECTED WITH THE MAIN RESERVOIR STRUCTURE THROUGH A RIGID CONDUCTIVE TUBULAR ELEMENT WHICH ALSO ACTS AS AN ELECTROPHORESIS ELECTRODE. THE TUBULAR ELEMENT AND NOZZLE ELEMENT TAPER PROGRESSIVELY TOWARDS A SMALL OPENING IN THE NOZZLE AT WHICH THE COATING FLUID IS DISPENSED WITH CAPILLARITY, THE OPENING IN THE NOZZLE IS ADAPTED TO CONTACT AND CONFORM TOTHE RECEPTIVE SURFACE AT THE SITE SELECTED FOR COATING. THE TOOL INCLUDES A BATTERY COMPARTMENT AND EXTERNAL CONNECTION LEAD FOR SUPPLYING VOLTAGE TO GENERATE THE ELECTROPHORETIC DEPOSITS.

Abstract: APPLICATION TECHNIQUES AND MATERIAL DESIGN PROPERTIES AND FORMULATIONS ARE DESCRIBED FOR ELECTROPHORETICALLY DEPOSITED HOSTILE ENVIRONMENT PROTECTIVE COATINGS FOR EXPOSED CRITICAL METALLIC SURFACES. FORMULATION PROPERTIES AND EXAMPLES OF ELECTROPHORETICALLY DEPOSITABLE AQUEOUS POLYMER LATICES AND/OR CO-BLENDS OF AQUEOUS POLYMER LATICES ARE DISCLOSED. SAID LATICES AND/OR LATICE BLENDS HAVING SUCH DESIRABLE COATING PROPERTIES AS LOW GAS TRANSMISSION, ADHESION, NON-FLAMMABILITY CRACK RESISTANCE, FLEXIBILITY, SELECTED AND USEFUL DYE COMPATIBILITY, REQUISITE THICKNESS, ELECTRICAL REQUIREMENTS AND CHEMICAL RESISTANCE, ARE ILLUSTRATED FOR THE GENERIC LATICE BLENDS, POLYVINYLIDENE CHLORIDE (SARAN) AND EPOXY ESTER.
