Abstract: The world seeking alternative sources for adhesives production by using renewable raw material. In this context, the use of Stryphnodendron adstringens (Mart.) Coville tannins bark have been showing potential. The aim of this study was to evaluate the technical feasibility of using tannic adhesive from the barks of barbatimão, for particleboard production. Tannin-based adhesives extracted from the bark of barbatimão were used in ratio of 0, 25, 50, 75 and 100% with commercial urea formaldehyde adhesive. Pure and mixtures adhesives had their properties determined. Particleboards with urea-formaldehyde, tannin-formaldehyde and its mixtures were produced and had their physic-mechanical properties tested. The adhesive tannic of barbatimão proved be technically feasible in the proportion until 50% for particleboard panels type, however, it is recommended to indoors use only, without moisture contact.
