| 摘要 |
The invention relates to an aqueous coating composition (A), comprising at least one binder (A1) that can be cathodically deposited and possibly at least one cross-linking agent (A2), for at least partially coating an electrically conductive substrate with an electrophoretic dip paint, wherein the coating composition (A) has a pH value in a range of 4.0 to 6.5 and contains a total amount of at least 30 ppm of bismuth, with respect to the total weight of the coating composition (A), and wherein at least 0.005 wt% of magnesium oxide particles (B), with respect to the total weight of the coating composition (A), is used to produce (A). The invention further relates to a use of (A) to at least partially coat an electrically conductive substrate with an electrophoretic dip paint, to a corresponding coating method, and to an at least partially coated substrate that can be obtained according to said method. |
