Evaluation of Resistance Properties of Selected Surface Treatments on Medium Density Fibreboards

Abstract

The protection and decorative value of raw wood-based boards with various coatings can be enhanced during the service life of furniture using surface treatment techniques. In this study, selected transparent, pigmented polyurethane email finish and thin foils, commonly used in furniture, were used for surface treatments of medium-density fibreboards with a thickness of 18 mm. Water-borne finish with polyurethane–acrylate resin, solvent-borne finish with polyacrylate resin, and finish based on native oil and waxes, as well as pigmented polyurethane email finish, were used on veneered medium-density fibreboards. The thin foils (polyvinyl chloride, polyethylene terephthalate, and lacquered acryl film) were used for raw medium-density fibreboards. Several resistance surface properties were investigated. It was found that the hardness and resistance to impact were very much related to the interactions between the coating film or thin foil and the substrate. The type of surface finish had a substantial impact on the coating and foil’s resistance qualities, such as resistance to mould and cold liquids.
