METHOD FOR COATING METALLIC SURFACES WITH AN AQUEOUS COMPOSITION, THE AQUEOUS COMPOSITION AND USE OF THE COATED SUBSTRATES |
摘要 |
<p>The invention relates to a method for coating a metallic surface with a composition. This method is characterised in that the composition contains the following in addition to water: a) at least one organic film former containing at least one polymer which is soluble in water or is dispersed in water; b) a quantity of cations and/or hexafluoro complexes of cations selected from the group comprising titanium, zirconium, hafnium, silicon, aluminium and boron; and c) at least one inorganic compound in particle form with an average particle diameter of 0.005 to 0.2 mum, measured with a scanning electron microscope. The clean metallic surface is brought into contact with the aqueous composition and a film containing particles is formed on the metallic surface. This film is then dried, the dry film having a layer thickness of 0.01 to 10 mum. The invention also relates to a corresponding aqueous composition.</p> |
