Abstract
Due to European environmental regulations, solvent-borne wood coating systems have to be replaced by water-borne and high solid coatings. Thorough research is yet needed to replace the traditional solvent-borne systems by water-borne paints and stains for exterior wooden joinery. In this article the penetration of paint primers and wood stain base-coats (solvent-borne and water-borne as well as high solids and hybrid systems) in wood is discussed. Penetration is an important factor for the durability of a coating and thus the protection of the wood. For the image capturing a confocal scanning lasermicroscope (CSLM) was used. Penetration was measured using two methods. Further statistical analysis was done to determine the factor that influenced the penetration the most.
