Abstract (en)
[origin: EP1801262A1] Conversion process comprises carboxylation of a metallic surface e.g. zinc, iron, aluminum, copper, lead and their alloys, galvanized steels, electrozincated, aluminized, coppered, under oxidizing conditions with an aqueous/organic water bath containing a mixture of organic acids comprising 10-18 carbon atoms. Conversion process comprises carboxylation of a metallic surface e.g. zinc, iron, aluminum, copper, lead and their alloys or galvanized, electrozincated, aluminized or coppered steels under oxidizing with an aqueous/organic water bath containing a mixture of organic acids comprising 10-18 carbon atoms in a binary or ternary form, where respective proportions of for the binary acid mixture is x+-5:y+-5 molar ratio, where x and y are two acids in a mixture in the eutectic composition and for a ternary mixture x+-3:y+-3:Z +-3 molar ratio, x, y and z are three acids in a mixture in the eutectic composition in which the concentration of the mixture is >=20 g/l.
