Title (EN) AQUEOUS PROTECTIVE AND ADHESION PROMOTING COMPOSITION
(FR) COMPOSITION AQUEUSE PROTECTRICE AUGMENTANT L'ADHERENCE
Abstract:
(EN) An aqueous composition for coating a metallic substrate that is prepared by mixing at least one silane (preferably at least two silanes), at least about 20 weight percent phosphoric acid based on the total weight of the composition, and water, wherein the composition is substantially free of an organic solvent and a chromium-containing compound. The pH of the composition must not be above 3. The composition can be coated on a metallic substrate, particularly an aluminum substrate, to provide a pre-treatment layer for adhering overcoats.
(FR) On prépare une composition aqueuse destinée à revêtir un substrat métallique en mélangeant au moins un silane (de préférence au moins deux), au moins 20 % en poids environ d'acide phosphorique par rapport au poids total de la composition, et de l'eau, la composition étant sensiblement exempte de solvant organique et de composé contenant du chrome. Son pH ne doit pas être supérieur à 3. On peut utiliser la composition pour revêtir un substrat métallique, notamment en aluminium, d'une couche de prétraitement qui augmente l'adhérence des couches de finition.
