Abstract (en)
[origin: WO9829580A1] The invention relates to a method for treating metallic surfaces consisting of zinc, magnesium or aluminium or of the alloys of zinc, magnesium or aluminium, to which lacquer, coatings of plastic material, paint, sealants or adhesives are applied after treatment. The treatment of the metallic surfaces takes place at between 10 DEG C and 100 DEG C by immersion, spraying or rolling with an aqueous solution. The solution has a pH of between 2 and 13 and contains one or more compounds of the type XYZ at a concentration of between 10<-5> and 1 mol/l. Y is an organic group containing between 2 and 50 C atoms and has a straight-chain structure. X is a COOH, HSO3, HSO4, (OH)2PO, (OH)2PO2, (OH) (OR') PO or (OH) (OR') PO2 group. Z is a OH, SH, NH2, NHR', CN, CH=CH2, OCN, epoxy, CH2=CR''-COO, acrylamide, COOH, (OH)2PO, (OH)2PO2, (OH) (OR') PO or (OH) (OR') PO2 group. R' is an alkyl group with between 1 and 4 C atoms. R'' is an H atom or an alkyl group with between 1 and 4 C atoms. Groups X and Z are each bonded to group Y in their final positions.
