Performance Effectiveness of the Amino Resin Based Laminating Adhesive to Laminate on Wood Composites

The objective of this study was to formulate a new low temperature thermosetting adhesive for plywood lamination and to evaluate the potential of the laminating adhesive on wood composite material. A fast setting powder based laminating adhesive was developed to paste the laminates on the wood composite materials so as to increase the productivity efficiency. The adhesive was formulated by taking powder amino resin (MR-202) as a base material with some tackifier and viscosity enhancer as special chemicals. Dispersion of adhesive was carried with ratio 1: 1 (adhesive: water) and the resultant adhesive was taken for laminate pasting on wood composite material. The chemical and mechanical properties of the laminated wood were carried out. The resultant dispersion adhesive which contain 50 % solid content approx. demonstrated the setting of laminates on wood composite material both at room temperature and at the temperature 60-700C with a shorter time than the conventional laminating adhesive used at present. The experimental data reveals that the resultant adhesive confirms the requirements when tested as per IS 4835: (1976) for the parameters like pH, solid content, moisture content, ash content, glue joint strength, early strength development and stability etc. The significant bonding of laminate at a shorter time without warpage and cracking shows encouraging results for the potential of this technology.
