“…Likewise, the viscosity followed the same pattern observed in the statistical comparison of solids content, in ascending order of black wattle, Acacia mangium and phenolformaldehyde adhesives, with respective values of 663, 2,169 and 5,456 cP. Usually, as pointed out above, high viscosities are undesired for application of adhesive formulations (Mori et al, 2001) because of the weak glueline. Nevertheless, this pattern was not observed in the present work, even with the high values presented by the phenol-formaldehyde and black wattle adhesives.…”
