A method for the production of a polymeric film on a metal surface as well as concentrate for this purpose and the treatment fluid

摘要

The present invention relates to a process for the production of a plastic film or a plastic film on a metal surface, in which a treatment liquid, which at the beginning of the wetting with the treatment liquid 0,1 to 50 w -% of a one or more resins containing non-volatile film-forming mixture and 99,9 to 50 w -% of a water-miscible or / and water-soluble solvent or / and water, on the metal surface, a film is formed, wherein the volatile fraction escapes at least partially, which is characterized in that the treatment liquid at the beginning of the wetting with the treatment liquid a temperature in the range of from 10 to 100 deg c, that the metal surface at the beginning of the wetting with the treatment liquid a by at least 20 deg c higher temperature than the treatment liquid and a temperature in the range from 30 to 700 deg c, and that the film of the treatment of the metal surface serves. Dollars a the present invention also relates to a treatment liquid for the production of a plastic film or plastic film on a metal surface during the wetting of the metal surface with the treatment liquid, wherein the treatment liquid is 0,1 to 50 w -% of a one or more resins containing non-volatile film-forming mixture and 99,9 to 50 w -% of a water-miscible or water-soluble solvent or / and water, which is characterized in that ..
