Tannin-Based Wood Adhesives

  • Roland E. Kreibich


Past efforts aimed at replacing the phenolic material in wood adhesives by tannins of various origins have been extensive throughout the world, with research activity normally paralleling the price of phenol. With the exception of the use of “wattle” tannins for both thermosetting and cold-setting wood adhesives primarily in South Africa, success has been limited. More recent attempts (during the past 5 years) carried out in the United States to develop cold-setting wood adhesives for end-jointing and laminating lumber for structural applications requiring exterior glueline quality indicate substantial promise for the use of conifer tree barks as partial substitutes for resorcinol. These tannin-based, cold-setting adhesive formulations include an adhesive blend to be applied as a one-component system and a two-component “Honeymoon” system, each of which has been formulated either as face-laminating or end-jointing adhesives. In most formulations, half the resorcinol has been replaced by tannins extracted from the bark of southern pine trees.
