Sidon Keinert Júnior Mário Michaque M. Alberto About the authors

ABSTRACT

The objective of this research was to evaluate the effect of heating temperature of the logs, pressing time and pressing temperature on the glue line strenght of Pinus taeda phenolic plywood. A factorial analysis was applied for the different treatments showing that the best heating temperature was 60°C and the best pressing temperature 145°C, the pressing time was 9 minutes. The veneers and plywood produced showed the best properties.
