Strength of Acacia Wood with Polyurethane Adhesive
Introduction Acacia (Acacia mangium) as a medium density wood is one of fast growing species of Industrial Plantation Forest that has been developed in Indonesia. The connection system with glue is more compatible when applied on wood with medium density. The adhesive was used Polyurethane as Water Based Polymer lsocyanate, which was used in cold press application. The polyurethane adhesive product has wide commercial aplication, well known for their excellent adhesion, flexibility, high cohessive strength, low temperature performance, and has amenable curing speeds. Shear strength of Polyurethane was signficantly stronger than recorcinol (Vick, 1998). Burdulu et all., (2006) expressed that it was necessary to sand the surfaces prior to the bonding process to have a higher shear strength. Wood relies on both interlocking and charge interactions to create a proper adhesive bond (Gardner, 2008). The most important factor in forming strong bonds is the achievment of high level of adhesion between adhesive molecules and wood molecules, cohesion is force that is expressed internally, while adhesion is a force that is expressed externally (Mara, 1992). To predict the bond quality of polyurethane adhesive on Acacia wood requires investigation on the reaction of them.
