Abstract: 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.

Abstract: A process for the treatment or pretreatment of containers made of aluminum, aluminum-containing alloys, magnesium-containing alloys, iron-containing materials such as steel, coated iron-containing materials such as galvanized steel, or aluminum alloys, tinplate, brass or bronze, in particular the treatment or pretreatment of bags, tubs, bottles, cans, canisters, casks or tubes, wherein the process steps for the treatment or pretreatment take place at the same time as the application of the lubricant, with the agent used for the pretreatment or treatment, which also contains or is a lubricant, not essentially consisting of titanium or zirconium with fluoride and polymer, the lubricant possibly being formed first in the agent for the pretreatment or treatment or in the formation of the coating produced therefrom.

Abstract: The invention relates to a process for the treatment or pretreatment of containers made of aluminium, aluminium-containing alloys, magnesium-containing alloys, iron-containing materials such as steel, coated iron-containing materials such as galvanised steel, galvanised metallic materials or metallic materials coated with aluminium or aluminium alloys, tinplate, brass or bronze, in particular the treatment or pretreatment of bags, tubs, bottles, cans, canisters, casks or tubes, in which the process steps for the treatment or pretreatment coincide with the application of the lubricant, with the agent used for the pretreatment or treatment and which also contains and/or is a lubricant essentially not comprising titanium and/or zirconium together with fluoride and polymer, the lubricant optionally being formed only in the agent for the pretreatment or treatment and/or being formed during the formation of the coating produced therefrom.
