Abstract (en)
[origin: WO2018036806A1] The present invention relates to the use of an adhesion promoting organic compound comprising at least one tertiary amine group which in turn is bonded via a bridge-constituting divalent radical with the carbonyl carbon atom of an amide group, wherein the bridge-constituting divalent radical comprises two carbon atoms as bridge atoms, for anticorrosion pretreatment of metallic materials before painting. Aqueous compositions which generate conversion layers based on the elements Zr, Ti and/or Si are in accordance with the invention. The present invention further comprises a process for anticorrosion coating of components at least partly manufactured from metallic materials comprising a pretreatment using acidic aqueous compositions according to the invention and subsequent painting. In a further aspect the invention relates to a metallic substrate having a mixed organic/inorganic coating consisting of oxides, hydroxides and/or oxyfluorides of the elements Zr, Ti und/or Si and of the adhesion promoting organic compounds.
