Extenders are added to adhesive formulations to reduce resin utilization leading to cost savings. In this work, urea-formaldehyde resin was synthesized in the laboratory and cassava .flour was added to the urea~ormaldehyde resin in adhesive mix formulations for interior plywood manufacturing using a laboratory press. These formulations were compared with similar ones using wheat .flour as extender. There were five extension levels (/5.6, 31.2, 46.8, 62.4 and 78.1%) and three pressing times (4… CONTINUE READING
