A composition based on phenolic resin comprising at least one phenolic resin, a vegetable protein hydrolysate, preferentially a wheat gluten hydrolysate, and an agent for accelerating curing, and also to the process for the production thereof.

Wood adhesives for producing particle boards

A biocompatible bone graft for implanting into a bone wound site or screening a bone disease drug, comprising a porous scaffold structure made from a tannin-hydroxyapatite resin, a population of osteocompetent stem cells, and a growth medium. Methods of synthesis and physical characterization of the porous scaffold structure are described, as well as biological testing of the osteocompetent stem cells of the bone graft.

A method for producing polyHIPE porous monoliths, of the polyHIPE type or in the form of a rigid foam, by hardening solutions of condensed tannins in the presence of oil and/or air or in the presence of a non-water-miscible volatile solvent and/or air. Also disclosed is the use of these materials in the areas of catalysis, chromatography, heat and sound insulation, tissue engineering and medication release and as a floral foam.

Cellular porous monoliths containing condensed tannins

A thermo-set resin composition comprising a Quebracho wood tannin extract, a furfuryl alcohol, a neoprene compound, a dimethicone, polyethylene glycol, abrasive particles, and a glycerol phosphate acidic ester and/or graphite. Further, a method of preparing the thermo-set resin composition including mixing Quebracho wood tannin extract with a furfuryl alcohol to form a primary mixture, adding additives and abrasive particles to the primary mixture, and reacting the primary mixture by adding a catalyst. The thermo-set resin composition is molded into a shape under heat and pressure to a Brinell hardness 8.5 daN/mmand 48 daN/mmand can be incorporated into a friction pad of a brake pad.

A composition for manufacturing a foam material based on flavonoid tannins, includes a flavonoid tannin powder mainly of the prorobineditinidin and/or the profisetinidin type, according to an amount in weight in the range between 40% and 45% of the composition, furfuryl alcohol, a blowing agent, and a catalyst. The composition is totally formaldehyde-free, and contains an amount of furfuryl alcohol greater than 20% in weight of the composition. The composition makes possible to obtain foam materials of high characteristics and low cost, that can typically be used in the fields of building and in the automotive industry and in the vehicles in general.
