Abstract (en)
[origin: WO2013104835A1] The invention relates mainly to the use of an aqueous treatment solution containing sulphate ions SO4 2- at a concentration of greater than or equal to 0.01 mol/l, for treating a metal sheet comprising a steel substrate coated on at least one of its faces with a coating comprising at least zinc and magnesium, in order to reduce the blackening or tarnishing of the metal sheet during the storage thereof. The invention also relates to the metal sheet treated with such a solution.
