The present invention consists in a new type of adhesion material and the method of production. This material is used in the medical area, or in areas where is necessary to connect a device to the skin. This connection occurred due to the polarity that exists in the two materials, more concrete through the electric bounds, in more specific the bound obtained is a hydrogen bound that is produced when the two materials are connected. The adhesion material comprises polyethylene glycol, citric acid, ascorbic acid, one or more sugars or sugar alcohol, glycerol as well as a lauric acid and/or oleic acid mixture with polypropylene grafted with maleic anhydride or Polyethylene grafted with maleic anhydride or poly (ethylene-alt-maleic anhydride) or polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene-graft-maleic anhydride or polyisoprene-graft-maleic anhydride or poly(methyl vinyl ether-alt-maleic anhydride) or poly(isobutylene-alt-maleic anhydride) or poly(maleic anhydride-alt-1-octadecene) or poly(ethylene glycol)methyl ether methacrylate solution.
