Evaluation of wood surface coating performance using water based, solvent based and powder coating
The objective of this study was to evaluate the surface coating performance using water base, solvent base and powder coating on medium density fiberboard. Samples were coated using water-base, solvent-base and powder coating. Coating performance was performed by using adhesion strength, surface coating hardness, layer thickness and rapid deformation test. The results were analyzed with two different statistical methods. Adhesion strength, layer thickness and surface hardness were determined by using ANOVA analysis, while results of rapid deformation test were analyzed by using Kruskal-Wallis method. According to these results, coating type was effective factor on the adhesion strength, surface coating hardness, layer thickness and rapid deformation test. Water-based painting application for adhesion strength and impact deformation resistance was higher than solvent-based coating. In the powder coating application, although surface coating hardness was higher than solvent and water base coating application, rapid deformation results were lower than solvent and water base coating applications. Adequacy of models was performed R-square (R²) and Adjusted R-square (Adj-R2) values. R2 values of adhesion strength, layer hardness and film layer thickness were 93.60 %, 95.33 % and 73.90 %, respectively. Adj-R2 values of adhesion strength, layer hardness and film layer thickness were 93.45 %, 95.23 % and 73.30 %, respectively.
