Preparing medium density fiberboard surfaces for powder coating : effects of atmospheric plasma treatment, infrared irradiation, and climatization

  • The powder coating of wood products as an emerging environmentally sustainable coating technology holds promise in terms of novel product quality features for engineered wood like medium-density fiberboards (MDFs). However, one major limitation currently impeding widespread application of powder coating technology is the availability of MDF panels that are suitable for this process. Typically, special-grade MDF panels are required that are more costly than standard-grade MDF panels to provide reliable coating quality, which makes powder coating economically unattractive for many users. Methods are needed that allow extending the range of available MDF grades. In the present study, three surface pretreatment approaches for MDFs were studied to increase the processability of standard-grade MDF in the powder coating process: atmospheric plasma pretreatment, infrared irradiation, and moisture equilibration in a climate chamber prior to electrostatic powder application. While atmospheric plasma treatment had no beneficial effect on the use of standard-grade MDF panels, both infrared preheating and preconditioning of the panels under controlled temperature–humidity conditions demonstrated that the range of MDF panels suitable for powder coating can be significantly extended by appropriate selection of the pretreatment procedure.
