DescriptionWoodworkers know that wood is porous in that adhesive flows into lumens for a mechanical interlock (1) and that wood absorbs water, allowing the use of water-borne adhesives. However, the anatomical aspects of wood that lend to its porosity are much more complicated and have a greater influence on adhesive performance than is normallyrealized or discussed. This porosity can have both positive and negative effects on adhesive performance. A greater appreciation of how porosity relates to adhesive performance is important in designing new and improved adhesive formulations.
