Abstract

Cette composition aqueuse de traitement de surfaces telles que des métaux, notamment l'aluminium, comprend un silicate de tétraalkyle ou un produit d'hydrolyse de celui-ci, monomère ou oligomère, de même qu'un sol d'oxyde hydraté, par exemple un sol de silice, en dispersion dans un milieu aqueux fluide. On peut appliquer cette composition en tant que revêtement de prétraitement, afin d'améliorer l'adhésion d'une peinture, d'une laque ou d'un adhésif appliqués ultérieurement.
