Abstract:
Disclosed herein are cathodic electrocoat compositions which contain electroconductive pigments. These pigments are light in color, and can be added at higher pigment to binder ratios for improved edge coverage. More specifically, the electroconductive pigments are a two-dimensional network of antimony-containing tin oxide crystallites which exist in a unique association with amorphous silica or with a silica-containing material.
