Abstract (en)
[origin: CA3047184A1] The present invention relates to a method for the corrosion-protective and cleaning pretreatment of metallic components, produced at least partially from metallic materials from the elements iron, zinc and/or aluminium, with the use of an acid aqueous composition containing, in addition to the water-soluble compounds of the elements Zr and/or Ti causing the conversion of the metal surface, a mixture of an aliphatic diol and an aliphatic saturated polyhydroxy compound. It also comprises a chrome(VI)-free aqueous composition based on the constituents mentioned above which delivers outstanding results in cleaning and simultaneous corrosion-protective conversion of technical metal surfaces in one method step.
