Abstract
An electrocoat system for electrodeposition is described. The system includes an inorganic bismuth-containing compound or a mixture of inorganic and organic bismuth-containing compounds. The system demonstrates a high degree of crosslinking and produces a cured coating with optimal crosslinking and corrosion resistance.
Claims12
A composition for electrodeposition, comprising:
- an electrodeposition resin component;
- optionally, a crosslinking component;
- optionally, an acid component;
- and
- at least an inorganic bismuth salt of a metal oxyanion bismuth-containing compound comprising bismuth aluminate.
2 more elements
A method, comprising:
- combining an electrodeposition resin component including at least one crosslinkable functional group with a blocked isocyanate component;
- an aliphatic carboxylic acid component;
- and
- at least an inorganic bismuth salt of a metal oxyanion bismuth-containing compound comprising bismuth aluminate.
1 more element
A method for electrodeposition, comprising:
- providing an emulsion including a cationizable electrodeposition resin component and a blocked polyisocyanate crosslinker component;
- providing a pigment paste including a dispersion resin, pigment, and an inorganic bismuth salt of a metal oxyanion bismuth-containing compound comprising bismuth aluminate.
