Title (EN) COMPOSITION AND PROCESS FOR TREATING METAL SURFACES
(FR) COMPOSITION ET PROCEDE DE TRAITEMENT DE SURFACES METALLIQUES
Abstract: front page image
(EN)A composition for treating metal surfaces that contains, at a weight ratio from 1:5,000 to 5,000:1, at least one metal acetylacetonate selected from the group consisting of Al(C¿5?H¿7?O¿2?)¿3?, V(C¿5?H¿7?O¿2?)¿3?, VO(C¿5?H¿7?O¿2?)¿2?, Zn(C¿5?H¿7?O¿2?)¿2?, and Zr(C¿5?H¿7?O¿2?)¿4?, and at least one compound selected from water-soluble inorganic titanium compounds and water-soluble inorganic zirconium compounds provides a non-chromate-type composition for imparting an excellent corrosion resistance and paint adherence to the surfaces of metals, particularly aluminum and its alloys, magnesium and its alloys, and zinc and its alloys.
(FR)Une composition de traitement de surfaces métalliques contenant, en un rapport pondéral de 1:5000 à 5000:1, au moins un acétylacétonate métallique choisi dans le groupe contenant Al(C¿5?H¿7?O¿2?)¿3?, V(C¿5?H¿7?O¿2?)¿3?, VO(C¿5?H¿7?O¿2?)¿2?, Zn(C¿5?H¿7?O¿2?)¿2?, et Zr(C¿5?H¿7?O¿2?)¿4?, ainsi qu'au moins un composé choisi entre des composés de titane organiques hydrosolubles et des composés de zirconium organiques hydrosolubles, fournit une composition de type non chromate conférant une excellente résistance à la corrosion et une excellente adhérence des peintures à des surfaces de métaux, en particulier l'aluminium et ses alliages, le magnésium et ses alliages, le zinc et ses alliages.
