A series of commercially manufactured medium density fiberboard (MDF) panels were
exposed to a post-manufacture heat-treatment at various temperatures and durations using
a hot press and just enough pressure to ensure firm contact between the panel and the
press platens. Post-manufacture heat-treatment improved surface roughness of the exterior
MDF panels. Panels treated at 225° C for 30 min had the smoothest surface while the
roughest surface was found for the control panels. Wettability and the adhesive bonding …

A series of commercially manufactured medium density fiberboard (MDF) panels were exposed to a post-manufacture heat-treatment at various temperatures and durations using a hot press and just enough pressure to ensure firm contact between the panel and the press platens. Post-manufacture heat-treatment improved surface roughness of the exterior MDF panels. Panels treated at 225°C for 30 min had the smoothest surface while the roughest surface was found for the control panels. Wettability and the adhesive bonding strength between veneer sheet and panel surface were decreased as post-treatment press temperature increased. A significant relationship (R 2 = 0.92) existed between contact angles and adhesive bond strength.
