Abstract The curing process of two biobased adhesives: pine tanninhexamine (TH) and organosolv lignin non-isocyanate
polyurethane (NIPU), suitable for interior nonstructural use, were compared with commercial urea-formaldehyde
(UF) adhesive. Changes in chemical structure before and after the curing process were observed with Fouriertransform infrared spectroscopy (FTIR). The process of adhesive curing was monitored with differential scanning
calorimetry (DSC) and the automated bonding evaluation system (ABES). Both DSC and ABES measurements
confirmed UF as the fastest and NIPU as the slowest curing adhesive observed. Taking into account the ABES
results, the optimal pressing parameters for the TH adhesive would be 4 min… More >
