The infiltration and hardening of adhesive oligomers in the cell wall is proposed to both repair damage to cells near the bond surface and modify the cell wall; this results in a more gradual gradient of material properties between the bondline and the bulk wood, resulting in less concentration of swelling stresses when wet and therefore better bond performance.
