Abstract

1368031 Anodizing and deposition of resin SHINTO PAINT CO Ltd 30 March 1972 [31 March 1971] 15231/72 Heading C7B A method of treating an aluminium alloy article comprises making the article the anode in an electrolysis bath containing at least one acid containing -SO 4 or -SO 3 H groups, at least one polybasic organic acid containing no -SO 4 or -SO 3 H groups and at least one cationic type resin prepolymer or precondensate in an-aqueous system wherein the prepolymer or precondensate is anionized at least partly so that anodization and electro-deposition of the prepolymer or pre-condensate are effected on the surface of the article in a single bath. The strong acid may be sulphuric acid, sulphamic acid, sulphopthalic acid or sulphosalicylic acid and its concentration is at least 0À05 wt. per cent. The polybasic organic acid may be oxalic acid, tartaric acid, malonic acid, citric acid, maleic acid, phthalic acid, or malic acid and its concentration at least 0À3 wt. per cent. The concentration of the prepolymer or precondensate is 1-40 wt. per cent. The prepolymer or precondensate may be thermosetting and be heat treated after electrodeposition to cure the resin. Before heat treatment, the article may be washed in an aqueous solution containing organic solvents, a surfactant and an anti-oxidant. The organic solvent may be ethylene glycol ether or diethylene glycol ether. The cathode may be carbon, lead or stainless steel. The bath may be stirred. A semipermeable membrane may be used to prevent resin depositing on the cathode. If A.C. is used aluminium articles may form bath electrodes. Pre-treatment of the article may be degreasing, immersion in 10% NaOH, washing immersion in 10% HNO 3 then washing.
