Abstract
The present invention relates to an aqueous coating composition (A) having a pH in a range from 4.0 to 6.5 and comprising at least one cathodically depositable binder (A1), a total amount of at least 130 ppm of Bi, based on the total weight of (A), including at least 30 ppm of Bi in a form (A3) in solution in (A) and at least 100 ppm of Bi in a form not in solution in (A), and at least one at least bidentate complexing agent (A5) suitable for complexing Bi, (A5) being present in (A) in a fraction of at least 5 mol %, based on the total amount of the Bi present in (A), for at least partly coating an electrically conductive substrate with an electrocoat material, to a method for producing (A), to the use of (A) for at least partly coating an electrically conductive substrate with an electrocoat material, to a corresponding coating method, to an at least partly coated substrate obtainable by this method, and to a method for setting and/or maintaining the concentration of component (A3) and/or (A4) in the coating composition (A) during the coating method.
