The quality of adhesive bonding of veneered particleboards depends on several factors, including pressing temperature, carrier panels` humidity and moisture content of veneer. In the experiment exposed to relative air humidity of 0 %, 35 %, 65 %, 85 %, 95 %, and pressing temperatures of 110 °C and 90 °C were used. Pressing time for each temperature value was 5 minutes. On samples provided a bonding strength test was performed, and the moisture content values so as their volume mass recorded. The best characteristics were achieved using a veneer having moisture content of 1 % and pressing temperature of 90 °C. The worst characteristics were achieved using veneer having moisture content of 38 % and pressing temperature of 110 °C.
