  • Abstract

    Phenol urea-melamine formaldehyde (PUMF) resin adhesive was prepared by using phenol, urea and melamine in two different molar ratios. The effects of the molar ratio of formaldehyde, phenol, urea, melamine on performance of PUMF resin adhesive were studied. The resin developed was characterized by differential scanning calorimeter (DSC) and Fourier transform infrared spectroscopy (FTIR). Plywood was manufactured using the developed resin and bonding properties were evaluated as per IS: 848-2006. The results indicated that the plywood made using PUMF resin of the molar ratio (phenol: urea: melamine): Formaldehyde 1:0.79:0.38:2.15 at pH 9.0 yield best result. The studies indicate that the PUMF can be used make wood-based panels of boiling water resistant grade.
