RESIN-COATED ALUMINUM ALLOY PLATE FOR BOTTOMED CYLINDRICAL CASE FOR CAPACITOR

WIPO Patent Application WO/2011/118027

A1

Disclosed is a resin-coated aluminum alloy plate for a bottomed cylindrical case for a capacitor, which has good drawing processability and ironing processability and is free from cracking of the resin coating film and separation between the aluminum alloy plate and the resin coating film during the processing. The resin-coated aluminum alloy plate for a bottomed cylindrical case for a capacitor is also free from deterioration of the coating film and corrosion of the base aluminum in a harsh environment after the processing. Specifically disclosed is a resin-coated aluminum alloy plate for a bottomed cylindrical case for a capacitor, which is composed of a substrate that is formed of an aluminum alloy plate, a chemical conversion coating film that is formed on the surface of the substrate, and a resin coating film that is formed on the surface of the chemical conversion coating film. The resin coating film is a cured product of a resin mixture that contains an epoxy resin having specific physical properties, a polyester resin, an amino resin and an isocyanate resin at a specific mixing ratio.
