Abstract
La présente invention a trait à un procédé de réalisation d'un revêtement de protection à la surface d'un article en aluminium, tel que des pièces de finition extérieure d'un véhicule automobile. Un revêtement anodisé est réalisé à la surface de l'article en aluminium. Les pores du revêtement anodisé sont ensuite scellés Une résine acrylique cationique thermodurcissable est appliquée par revêtement électrolytique sur la couche anodisée. La résine acrylique cationique thermodurcissable est soumise à un durcissement thermique. Le revêtement anodisé présente un degré de douceur suffisant de sorte que le durcissement de la résine acrylique cationique thermodurcissable maintient un revêtement anodisé continu et ne provoque aucune formation de fractures. Le revêtement anodisé est réalisé à une température d'environ 20 à 30 ·C, à une tension d'environ 10 à 15V, et une concentration en électrolyte d'environ 10 à 15 % en volume. La résine acrylique cationique thermodurcissable comprend un agent anti-UV. Le cas échéant, une étape de coloration électrolytique est effectuée préalablement au scellement des pores du revêtement anodisé.
