Adhesive bond of wood is a key factor in effective utilization of wood resources. Therefore, the evaluation of performance under different conditions of the wood products bonded with an adhesive is highly important. In this study, wood samples bonded with PVAc were subjected to water at different temperatures (20, 40, 60 and 80°C) for different durations (10, 20, 30 and 40 minutes). Once the experimental results were analyzed, it was observed that the bonding strength of the wood samples bonded

These drops observed in strength values reached to larger ratios as a result of treatment with water at 60°C and temperatures above. In addition, the drops in strength values increased generally with the increase of the exposure time.
