  • Use of an adhesion promoter obtainable as a reaction product of a di- or poly amine with ?,?-unsaturated carboxylic acid derivatives for metal surface treatment
    Patent number: 11535940
    Abstract: The invention relates to use of an adhesion promoting organic compound comprising at least one tertiary amine group, 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 and to aqueous compositions containing the adhesion promoting organic compound which generate conversion layers based on the elements Zr, Ti and/or Si. 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.

  • PRE-RINSE CONTAINING A QUATERNARY AMINE FOR CONDITIONING PRIOR TO A CONVERSION TREATMENT
    Publication number: 20180066365
    Abstract: A multi-step process for the anti-corrosive pretreatment of components component formed at least partially from metallic materials wherein first components are subjected to a conditioning wet-chemical treatment with an aqueous composition (A) that contains a salt of a quaternary amine and then to an additional wet-chemical treatment based on water-soluble compounds of the elements Zr, Ti and/or Si, in the course of which treatment a corresponding conversion of the surfaces of the metallic materials takes place, said treatment providing an anti-corrosive primer for additionally applied organic coatings.
