摘要: The present invention relates to a coating composition comprising at least one binder (A) comprising at least one polymeric resin (A1) and at least one crosslinking agent (A2), at least one anticorrosion pigment (B), and at least one organic solvent (C), where (B) is an alloy of Zn and Mg and optionally at least one further metal and/or semimetal, the coating composition having a pigment volume concentration (PVC) in a range from 5.0% to 25.0%, and comprising the anticorrosion pigment (B) in an amount in a range from 5.0 to 25.0 wt %, based on the total weight of the coating composition, to the use thereof for the at least partial coating of a metallic substrate with a primer coat, to a method for the at least partial coating of such a substrate with such a primer coat, to a substrate at least partially coated therewith, and to a component or article produced from such a substrate.

摘要: Described herein is an electrodepositable coating material including comprising one or more cathodically electrodepositable resins (A); one or more crosslinking agents (B); and one or more compounds represented by formula (I) where C(R1)(R2) is C═O or CH2; R3 is H or OH; R4 and R5 are H or OH, with the proviso that at least one of R4 and R5 is H; and R6-R7 is C═C or HC—CH. Also described herein is a method of coating a metallic substrate comprising including the steps of dipping a metallic substrate into an electrodeposition bath containing the electrodepositable coating material; switching the substrate as a cathode; depositing the electrodepositable coating material onto the substrate to form a coating layer; and drying and curing the thus formed coating layer. Further described herein is a method of using the compounds of formula (I) as anticorrosion agents in electrodeposition paints and coated substrates.
