Abstract
The objective of this study was to investigate the basic properties of eco-friendly adhesives produced from Tamarindus indica seed kernel powder (TKP) and to use them for fabricating particleboard. Four different types of adhesive were manufactured from TKP having certain percentage of polyvinyl alcohol (PVA), citric acid (CA), glucose, acetic acid, sodium bicarbonate, urea and potassium permanganate. Solid content, Gelling time, FTIR, Thermogravimetric analysis (TGA), viscosity and single lap joint test for shear strength of the prepared adhesives were tested. Both the physical and mechanical properties of the experimental particleboards were evaluated followed by ASTM standards. Adhesive type A resulted in the quickest gel time (1.42 min) and the highest bonding strength (5.18 MPa). Adhesive type B having the density of 0.65 g/cm3 showed the highest modulus of elasticity (2108 N/mm2) and modulus of rupture (10 N/mm2). Although dimensional stability of the experimental panels was poor but their overall mechanical strengths properties met the values listed in the standards.
