  • Polymer-containing pre-rinse prior to a conversion treatment
    Patent number: 11230768
    Abstract: A multi-step method for anti-corrosion pretreatment of components made from metallic materials, in which a wet chemical treatment with an aqueous composition (A) containing a dissolved and/or dispersed polymer P, which is substituted with heterocycles containing at least one quaternary nitrogen heteroatom, is followed by a conversion treatment based on water-soluble compounds of the elements Zr, Ti, and/or Si before further anti-corrosion coatings are optionally applied.
    Type: Grant
    Filed: October 13, 2017
    Date of Patent: January 25, 2022
    Assignee: Henkel AG & Co. KGaA
    Inventors: Sophie Cornen, Kristof Wapner, Ralf Posner, Natascha Henze, Kirsten Agnes Lill, Michiel Gerard Maas
  • 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.
