Adhesive composition, characterized in that it consists of: - at least one monosaccharide and / or at least one polysaccharide having a weight-average molar mass, determined by gel permeation chromatography, of less than 10000, - an organic polycarboxylic acid which is citric acid, monosaccharide and / or polysaccharide representing 30 to 80% by weight of the mixture consisting of monosaccharide and / or polysaccharide and organic polycarboxylic acid, - a catalyst selected from Lewis acids and bases, compounds containing phosphorus and compounds containing fluorine and boron, the catalyst representing at least 1% and up to 20% by weight of the monosaccharide and / or the polysaccharide and the organic polycarboxylic acid, - water and calculated on the basis of 100 parts by weight of monosaccharide and / or of polysaccharide and of organic polycarboxylic acid, - 0 to 2 parts of silane, in particular an aminosilane, - 0 to 20 parts of oil, - 0 to 30 part of urea and / or glycerol, - 0 to 5 parts of a silicone, - 0 to 30 parts of an "extender" selected from lignin derivatives, such as ammonium lignosulfonate (LSA) or sodium lignosulfonate, and animal or vegetable proteins. |
