Coating quality of film-faced plywood as a function of pressing cycle

The aim of this study was to evaluate the effect of process parameters on the coating quality of film-faced plywood using variables such as phenolic film grammage, press temperature, specific pressure, and pressing time. Coating quality was evaluated in 48 panels tested by resistance to abrasion and steam absorption, followed by statistical factorial analysis. The highest phenolic film grammage showed better results in the abrasion test. Pressing parameters did not affect the absorption of steam. We recommend the performance of phenolic coating under the following conditions: grammage: 215 g/m², temperature: 130 ºC; specific pressure: 16 kgf/cm²: pressing time: 6 minutes.
