Abstract
Reliable wood-adhesive bonds are crucial for future wood-biomass utilization. This ongoing research aims at systematically investigating interactions between adhesives and extractable wood constituents. The simultaneous examination of the progress of chemical reactions and changes in rheological properties of both pure adhesives and adhesive-extract mixtures, using a combination of FTIR spectroscopy and rheology, confirms major influences on the curing process of the melamine urea formaldehyde (MUF) adhesive and provides fundamental information on their chemical interpretation.
