Abstract

A component with a self-healing surface layer, a self-healing enamel and a coating powder are disclosed. A self-healing is guaranteed by a reactive substance, which is encased in sheathed particles. Only damage to the enamel coating leads to a destruction of the coating, preferably under the influence of a catalytic material, so that the encased fluid enamel can emerge. Under the effects of UV light the fluid enamel cures and seals the crack thus occurring.
