Production of EGP with Different PVAc Adhesives and Pressing Systems

ABSTRACT One of the reconstituted products of great importance, characterized as a high-value product, is edge glued panel, whose quality depends on factors inherent to the wood and the production process. In this context, the objective of this research is to evaluate the quality of bonding of EGP panels of Pinus taeda, produced with different PVAc adhesive formulations and pressing systems. A completely randomized design in a factorial arrangement was used (4×2) respectively for PVAc adhesive formulations (class D3) and cold pressing and high frequency. The quality of bonding was evaluated by the standards EN 204: 2001 and EN 205: 2002. The results showed no statistically significant difference from the interaction of adhesive formulations and pressing system, and none of the treatments reached the minimum requirement of EN 204:2001, however, the shear strength results are consistent with industrial results.
