Abstract Various crosslinking agents can be added to the formulations of natural-based adhesives for wood bonding in
order to achieve better durability and higher strength of the formed joints. In the present study, the effect of hexamethylenediamine (HMDA) addition on the performance of liquefied wood (LW) adhesive for wood bonding is
investigated. Differential scanning calorimetry showed the improved thermal stability and crosslinking of the LW
adhesive with HMDA. The intensified presence of amide linkages (C–N bonds) was found in LW+HMDA with
attenuated total reflection Fourier transform infrared spectroscopy. Analysis of the bonded joints using an automated… More >
