Effect of Solid Content of Adhesive on the Compression Strength of Finger Jointed Sections

An experiment was conducted to assess the effect of solid content of urea formaldehyde (UF) adhesive on the compression parameters of finger jointed sections of Eucalyptus wood. Three concentrations designated as UF1, UF2 and UF3 had solid contents of 36.8 %, 44.9 % and 57.6 % respectively. All three concentrations showed good efficiency under compression parallel to grain when small sections were joined with finger jointing. The study illustrated that a UF concentrations at 36.8 % to 57.6% solid content range can perform equally well when eucalyptus sections are joined with the finger profile used in the study.
