An effort to reduce formaldehyde emission from wood adhesives is to replace them with alternative bio- based adhesives that have similar properties and adhesive qualities. The ingredients used are derived from the bark extract of the palm trunk (Elaeis guineensis Jacq.). The best formulation for adding phenol-formaldehyde (PF) resin in bio-based adhesive synthesis was characterized by the physical and chemical properties to be applied to the laminated wood. These characteristics are in the form of appearance, pH, solids content, specific gravity, viscosity, total phenolic content, and the components of the compounds contained in the bioadhesive. The resulting sengon laminated wood was characterised to determine the optimum formulation with delamination test parameters, moisture content, and formaldehyde emission. The results showed that the best bio-based adhesive formulation from palm bark was adding 7.5% (w/w) PF resin. [ABSTRACT FROM AUTHOR] |
