This invention relates to compositions suitable for use as coatings. More particularly, this invention relates to compositions suitable for use as industrial coatings such as anti-corrosion coatings, protective coatings and adhesive coatings. This invention relates to compositions and methods for coating substrates. More particularly, the invention relates to coating compositions and methods for coating substrates, where the coating compositions comprise polymerized olefins and cyclic olefins, via different chemical transformations. The invention also relates to methods of applying the coatings to the substrates.

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.
