(EN) NON-CHROMATE CONVERSION COATING TREATMENT FOR METALS
(FR) TRAITEMENT DE METAUX PAR COUCHE DE CONVERSION NON CHROMATIQUE
Abrégé
(EN)
Chromate-free treatments and compositions, for applying a conversion or passivation coating to zinc coated metal surfaces. The compositions comprise a polyamidoamine/epihalohydrin polymer or cationic polyamine/epihalohydrin polymer component, fluoacid, H3PO4, and a film forming polymer latex component. The requisite metal surfaces are contacted by the compositions and dried. Rinsing is optional.
(FR)
L'invention concerne des compositions et des traitements exempts de chromate utilisés pour appliquer une couche de conversion ou de passivation sur des surfaces métalliques galvanisées. Ces compositions contiennent un composant polymère polyamidoamine/épihalohydrine ou un composant polymère polyamine/épihalohydrine cationique, un fluoacide, H3PO4, ainsi qu'un composant latex polymère filmogène. Les surfaces métalliques recherchées sont mises en contact avec lesdites compositions, puis elles sont séchées.
