ABSTRACT
This paper was developed to evaluate the quality of structural plywood using the phenolic surface film. The plywoods were manufactured using five veneer of Pinus taeda with 2 mm thickness. The boards were pressed with temperature of 140ºC and 160ºC; specific pressure of 1,5 and 2,0 MPa; press time to achieve the temperature of resin curing, plus 1 and 2 minutes. The results of the glue line tests - dry and humity, showed that the use of press temperature of 160ºC and specific pressure of 2,0 MPa, are the better conditions to plywood manufatures using phenolic surface film. Using the better conditions of press parameters to board pressing, the plywood manufactured with phenolic surface film could present higher bonding quality in comparison to plywood manufactured with the liquid phenolic resin.
