Abstract (en)
[origin: WO2016193005A1] The invention relates to a multi-step process for the anti-corrosive pretreatment of components which consist of metallic materials. The components are first 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.
