摘要：
A method for coating a metallic surface with an aqueous composition for pretreating before applying another coating or for treating said metallic surfaces. The method is characterized in that the composition contains, in addition to water; a) at least one hydrolyzable or at least partially hydrolyzed fluorine-free silane, and; b) at least one hydrolyzable or at least partially hydrolyzed fluorine-containing silane. The invention also relates to corresponding compositions.
