POLYMERIC COATING MIXTURE, METHOD FOR APPLYING THIS COATING MIXTURE TO A METALLIC BASE FOR PROTECTING AN EDGE OR A PART, PROTECTIVE LAYER, A BASE COATED IN THIS MANNER AND THE USETHEREOF

摘要

The invention relates to a coating mixture for applying a polymeric, corrosion- preventing protective layer to a metallic base for protecting an edge area, a soldered point, a weld seam and/or a repair point or for sealing the seam of one or more optionally interjoined strips, metal sheets and/or shaped parts. According to the invention, the coating mixture is largely or entirely free of water and/or of organic solvents, whereby it contains at least one radically polymerizable binding agent and at least one compound that forms free radicals when subjected to the action of actinic radiation. This radically polymerizable compound is largely or completely cured with the formed free radicals when subjected to actinic irradiation. The invention also relates to a coating mixture of the aforementioned type that additionally contains at least one post-crosslinking compound, whereby the radically polymerizable compound, when subjected to actinic irradiation, does not completely cure with the formed free radicals at temperatures ranging from 10 to 200 ~C but additionally has reactive bonds that lead to an extensive or complete curing when brought into contact with the post-crosslinking compound(s). The invention additionally relates to a method for producing a polymeric corrosion- preventing protective coating using this coating mixture. Finally, the invention relates to a protective coating produced in the aforementioned manner or to a metallic base correspondingly coated and to the uses thereof.
