Abstract

BIANCHE, Juliana Jerásio et al. Shear in the Glue Line of Eucalyptus sp. Bonded with Different Adhesives and Weights. Floresta Ambient. [online]. 2017, vol.24, e00077114.  Epub Aug 03, 2017. ISSN 1415-0980.  http://dx.doi.org/10.1590/2179-8087.077114.

This work aimed to evaluate the shear strength of glue line joints of Eucalyptus sp bonded with different adhesives and weights. Bonding of Eucalyptus sp was performed using two hot-curing adhesives (phenol-formaldehyde and melamine-formaldehyde), four cold-curing adhesives (resorcinol-formaldehyde, sodium silicate, PVA (polyvinyl acetate) and castor oil-based polyurethane, the weights were 150, 200 and 250 g/m2 double sided.Shear strength and failure in wood and shear in wet conditions were determined. According to the results, castor and resorcinol adhesives showed higher shear strength in the glue line in dry condition. Castor and phenol formaldehyde adhesives showed higher failure percentage in wood in dry condition.

Keywords : castor adhesive; sodium silicate; bonding.
