An aqueous adhesive composition comprises a thermosetting resin based on: at least one aromatic compound bearing at least two functions, one of these functions being a hydroxymethyl function and the other being an aldehyde function or a hydroxymethyl function, the aromatic compound comprising at least one aromatic ring; and at least aromatic polyphenol comprising at least one aromatic ring bearing at least two hydroxyl functions in the meta position relative to one another, the two positions ortho to at least one of the hydroxyl functions being unsubstituted. Such an adhesive composition may especially be used to join elements made of wood; it constitutes an advantageous alternative to the use of a formaldehyde-based phenolic resin adhesive.

A binding compound for mineral or organic fibres, includes from 40 to 95 wt % of furan resin, and from 5 to 60 wt % of at least one reducing sugar and/or of at least one non-reducing sugar, relative to the total dry weight of the composition, the binding composition having a dry matter content between 0.5 to 50 wt %.

Composition including a first component, including furfuryl alcohol and humins and a second component including an acidic polymerization initiator. The composition can be oligomerized to a resin, which has a viscosity in the range of 0.1 to 10,000 Pa.Math.s at 25 C., determined according to ISO3219. The resin, or a blend of furfuryl alcohol and humins as a component A and an acidic polymerization initiator as a component B, separated from each other, may form a kit for an adhesive or impregnation agent.
