Steps to make the natural adhesive of Acacia mimosa tannin resistant to boiling water using Tinnevelly senna for particleboard production

Adding a small amount of Tinnevelly senna seed flour to the natural adhesive of condensed tannin from acacia mimosa type decreases the thickness swelling and water absorption in particleboards significantly. Likewise, internal bond, modulus of rupture and modulus of elasticity increase. FTIR did not show any change in the adhesive structure. DSC and TGA showed a link between the additive of Tinnevelly senna and natural adhesive of acacia mimosa tannin, which obviously brings about the resistance to boiling water in particleboard manufacturing when using this adhesive mix.
