CA 2346722

A conversion coating that does not substantially diminish the luster of a metal surface on which it is coated nor impair adhesion to the surface of lacquers and printing inks commonly used on beverage containers may be provided by contacting the metal surface with an aqueous liquid composition comprising water and at least the following components: (A) a component of one or more dissolved transition metal compounds that contain zirconium and may also inlcude titanium, provided that zirconium constitutes more than 30 % of the moles of the total moles or zirconium and titanium; (B) a component of at least one dissolved compound that contains inorganically bonded fluorine and is not part of component (A); and (C) a component of dissolved organic polymer molecules.

L'invention concerne un revêtement par conversion qui ne diminue pas de façon sensible le lustre de la surface de métal sur laquelle il est appliqué et n'empêche par l'adhérence sur la surface des vernis et encres d'impression habituellement utilisés sur les récipients pour boissons. On obtient ce revêtement en mettant la surface métallique en contact avec un liquide aqueux contenant de l'eau et au moins les composants suivants: (A) un composant d'un ou de plusieurs composés de métal de transition dissous contenant du zirconium et pouvant également contenir du titane à condition que le zirconium représente plus que 30 % des moles totales du zirconium et du titane; (B) un composant d'au moins un composé dissous qui contient un fluor à liaison inorganique et ne forme par une partie du composant (A,) et (C) un composant de molécules polymères organiques dissoutes.
