Abstract

A method for coating of a metallic article is provided. According to the method, the metal surface is coated with a composition which comprises a polymer or comprises a two-component system that reacts to form a polymer following application to the metal surface. The composition comprises 70-2700 meq/kg olefinic double bonds which leads to stronger adhesion and to increased corrosion resistance.
