CA 2396041

A metal treating composition comprising at least a specific type of dissolved and/or dispersed organic resin, a dissolved vanadium compound in which the valence of vanadium is from 3 to 5, and a dissolved compound that contains at least one of the metals Zr, Ti, Mo, W, Mn, and Ce can provide metal surfaces with superior corrosion resistance, alkali resistance, and fingerprint resistance. The composition contains no chromium to cause pollution problems and/or require pollution abatement.

Une composition de traitement de métal comprenant au moins un type spécifique de résine organique dissoute et/ou dispersée, un composé de vanadium dissous, dans lequel la valence de vanadium est de 3 à 5, et un composé dissous contenant au moins un des métaux parmi Zr, Ti, Mo, W, Mn et Ce, peut conférer à des surfaces métalliques une résistance supérieure à la corrosion, à l'alcali et aux marques de doigts. Ladite composition ne contient pas de chrome susceptible de poser des problèmes de pollution et/ou de nécessiter des mesures de réduction de la pollution.
