METHODS OF TREATING A METALLIC REINFORCEMENT SO AS TO FAVOR ITS ADHERENCE TO A RUBBER-BASE COMPOSITION AND OF PRODUCING AN ARTICLE WITH SAID REINFORCEMENT; REINFORCEMENTS AND ARTICLES OBTAINED BY THESE METHODS

摘要

Process for treating a reinforcement at least the surface of which is metallic so as to promote its adhesion to a rubber-based composition, characterised in that the surface of this reinforcement is placed in contact with a solution of at least one cobalt and/or nickel compound in at least one organic compound containing one or more hydroxyl groups at a temperature above 100 DEG C before the reinforcement is placed in contact with the composition.
