Abstract
The invention relates to a process for coating powders on wood substrate comprising pre-treating at least one surface of the substrate with a substantially solvent free treating composition, applying a powder coating composition on the pre-treated surface of the substrate; and curing the powder coating composition. The treating composition includes at least one thermoset material and has a viscosity that is sufficiently low to allow the treating composition to wet out the surface(s) of the substrate and to penetrate into the surface fiber structure of the substrate.
