Evaluation of adhesion strength of heat treated wood material using dipping and atomization methods

The aim of this study is to evaluate the heat treated wood coating performance using dipping and atomization methods. Heat treatment temperature, treatment time, wood direction and application types were selected as independent variables while adhesion strength was determined as a dependent variable. The artificial weathering test was used to determine the performance of the surface coating applied to the heat-treated wood materials. The factors affecting the surface coating performance after the artificial weathering test were evaluated by multivariate analysis of variance (MANOVA) and pareto analysis. According to results, adhesion strength was found to be higher in both methods at 190° C temperature and 2 hours of application time. Adhesion strength in the radial direction was found to be better than the tangential direction, and it was observed that especially the dipping method created a significant interaction on the material direction and affected the adhesion strength considerably.
