Abstract
An electrophoretic coating is disclosed. The electrophoretic coating comprises an aqueous medium and a charged film-forming resin dispersed in the aqueous medium. The film-forming resin is acid-insoluble and alkali-soluble.
Claims19
An electrophoretic coating, comprising:
- an aqueous medium;
- and
- a charged film-forming resin dispersed in the aqueous medium, the film-forming resin being acid-insoluble and alkali-soluble.
A method for preparing an electrophoretic coating, comprising:
- dispersing a charged film-forming resin in an aqueous medium comprising water and a water miscible solvent to obtain a film-forming resin dispersion, the film-forming resin being acid-insoluble and alkali-soluble.
An electrophoretic coating process, comprising:
- providing an electrophoretic coating comprising an aqueous medium and a charged film-forming resin dispersed in the aqueous medium, the film-forming resin being acid-insoluble and alkali-soluble;
- and
- coating a member with the electrophoretic coating using electrophoresis.
A selective plating process, comprising:
- forming a protective coating layer in a non-plated area on a plated surface of a substrate using an electrophoretic coating comprising an aqueous medium and a charged film-forming resin dispersed in the aqueous medium, the film-forming resin being acid-insoluble and alkali-soluble;
- plating the substrate;
- and
- stripping the protective coating layer from the non-plated area after plating.
