| 摘要 |
The present invention relates to an aqueous coating composition (A) comprising at least one binder (A1) amenable to cathodic deposition and optionally at least one crosslinking agent (A2) for the at least partial coating of an electrically conductive substrate with an electrodeposition coating, where the coating composition (A) has a pH in a range from 4.0 to 6.5 and contains a total quantity of at least 30 ppm of bismuth in relation to the total weight of the coating composition (A), where at least 0.01 % by weight of aluminium oxide particles (B), in relation to the total weight of the coating composition (A), is used for producing the aqueous coating composition (A), to a use of (A) for at least partial coating of an electrically conductive substrate with an electrodeposition coating, to a corresponding coating process and to an at least partially coated substrate obtainable according to this process. |
