Abstract

L'invention concerne des compositions aqueuses utiles en tant que prétraitements avant la peinture permettant de réduire la formation de rouille dans l'état non revêtu. Les compositions sont essentiellement constituées d'eau, d'un composé de chrome trivalent de formule Cr(HxPO4)3, x pouvant représenter 1,5 ou 2, un composé de silice et éventuellement du peroxyde d'hydrogène. La composition peut avoir un pH compris entre environ 1 et environ 4. Un procédé de traitement d'une surface métallique comprend la mise en contact de la surface avec de telles compositions aqueuses. Les compositions et les procédés offrent des avantages par rapport au prétraitement de métal phosphate de zinc supposé être la norme dans l'industrie.
