Title
(EN) WATER-BASED METAL TREATMENT COMPOSITION
(FR) COMPOSITION AQUEUSE DE TRAITEMENT D'UN METAL
Abstract
(EN)
Disclosed for use in treating a metal, e.g., an alloy of silver as aforesaid, is a water-based composition comprising a treatment agent selected from an alkanethiol, alkyl thioglycollate, dialkyl sulfide or dialkyl disulfide and at least one of an amphoteric, nonionic or cationic surfactant in a concentration that is effective to solubilise the treatment agent. Preferably the composition comprises at least a non-ionic relatively hydrophobic surfactant e.g. cocamide DEA. The composition is particularly suitable for the treatment of Ag-Cu-Ge alloys.
(FR)
L'invention concerne une composition aqueuse à utiliser dans le traitement d'un métal, par exemple un alliage d'argent, comprenant un agent de traitement choisi parmi alcanethiol, alkyl thiogylcollate, sulfure de dialkyle, et au moins un tensioactif amphotère, non ionique et/ou cationique en concentration efficace pour solubiliser l'agent de traitement. La composition comporte de préférence au moins tensioactif hydrophobe relativement ionique, par exemple du cocamide diéthanolamine. Cette composition convient particulièrement au traitement d'alliages Ag-Cu-Ge.
