Abstract

1363874 Electro-phoretic coating DOW CHEMICAL CO 29 Nov 1971[30 Nov 1970 26 March 1971] 55394/71 Heading C7B A conductive surface, e.g. of Fe, (phosphated) steel, Cu, Al, Cr, Mg, Sn, Ti, Ni, Pb, Zn, Mo, Pt, Ag, alloy thereof, conductive gels or polymers, or graphite, is coated with a film-forming polymer by cationic deposition immersed in an aqueous dispersion of cation-active particles of the polymer, containing sulphonium ion or dispersed by a sulphonium surfactant e.g. dodecyl- or vinyl benzyldimethylsulphonium chloride, to provide the cation-activity. When D.C. is used, the surface forms the cathode and the anode may be the electro-phoretic tank e.g. of graphitecoated metal. The counteranion Z<SP>-</SP> of the surfactant having formula R<SP>1</SP> R<SP>2</SP> R<SP>3</SP> S<SP>+</SP> Z<SP>-</SP>, where R<SP>1</SP> has 8-25C and R<SP>2</SP> , R<SP>3</SP> each have 1-18C, may be chloride, bromide, fluoride, nitrate, surface, bicarbonate, phosphate, acetate, maleate, citrate, propionate, fumarate, acrylate, benzoate, or hydroxide; any of R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP> may be a hydrocarbon radical or the chain length may be interrupted by O, S, N or P. The aqueous dispersion of polymer may be obtained by emulsion polymerization of one or more α-, #-ethylenically unsaturated monomers; many examples are specified of styrene, acrylate and vinylidene compounds. The dispersion may contain up to 0À1 normal supporting electrolyte e.g. diammonium hydrogen phosphate. The voltage e.g. 40 to 350 volts may be constant with decreasing current, or increasing with constant current; or the voltage may be pulsed, applied for short, intermittent times at 200 to 800 volts. Alternatively A.C. may be passed through the bath between two objects to be coated each having a conductive surface.
