Abstract
A method for anticorrosive treatment of metal surfaces, especially at edges and transitions of the metal components, characterized in that a self-adhesive tape is applied to the metal surface and the self-adhesive tape contains at least one layer with a material which is heated such that the material melts onto the metal surface and thus forms an anticorrosive layer.
Claims16
A method for the corrosion control treatment of metal surfaces, especially at edges and transitions of the metal components comprising applying a self-adhesive tape to the metal surface and heating the self-adhesive tape, wherein the self-adhesive tape comprises at least one layer with a material such that when the self-adhesive tape is heated the material melts onto the metal surface and so forms a corrosion control layer, wherein a polyacrylate material with a tackifier having tackifying resins as principal component is used as material of the layer of the self-adhesive tape, and a combination of a polyfunctional epoxide and a urethane derivative and/or urea derivative is used for crosslinking the polyacrylate material, wherein the crosslink does not occur before the melting temperature of the polyacrylate is reached.
The method of after melting and crosslinking have taken place, the corrosion control layer itself is painted or a further, paintable layer is applied to the corrosion control layer, and this further layer is subsequently painted.
