An adhesive composition comprising an ethylene-vinyl acetate copolymer containing from 1 to 8% by weight of vinyl acetate together with a finely-divided activated carbon at a weight percent in the range from 10 to 30% of the composition is provided. The carbon preferably has a particle size of less than 500, more preferably less than 300, microns and may be a bituminous coal-based (BPL) carbon. The composition is particularly suitable for adhesion of metal surfaces such as stainless or mild steel. L'invention concerne une composition adhésive contenant un copolymère d'éthylène-acétate de vinyle contenant de 1 à 8% en poids d'acétate de vinyle ainsi qu'un charbon actif finement divisé présent dans 10 à 30% en poids de la composition. De préférence, la taille en microns des particules de charbon est inférieure à 500 µm et idéalement, inférieure à 300 µm, et peut être du charbon à base de charbon bitumineux (BPL). Cette composition convient particulièrement pour l'adhésion de surfaces métalliques telles que l'acier inoxydable et l'acier doux.
