Wood Surface Inactivation and Adhesive Bonding
From the instant an adhesive is applied to wood until the adhesive cures, several important steps must take place in order for a good glue bond to occur. If any of these steps do not occur, the glue bond will be faulty. Such is the case when gluing wood which is surface inactivated. The definition, causes, and prevention of surface inactivation in wood will be discussed below.
