The use of medium density fibreboard (MDF) is growing. The industry is looking to UV powder coatings to offer a feasible means of producing high-quality finishes for wood-based substrates. The powders can be sprayed on most MDF types using conventional corona or tribo charging guns. To melt the applied powder efficiently, medium wave infrared radiation (IRM) is used. When coating shaped MDF substrates, convection is reommended. The formulations, both clear and pigmeted, can be cured with normal mercury vapour lamps. For both furniture and building applications, texture finishing foils are commonly used on wood-composite substrates. Comparable finishes can be obtained when using UV-curable powder coatings. The use of clear UV powders on wood-composite panels laminated with wood-grain decor paper is another application. The resulting coatings form a good protective layer at low coating thickness and the new approach can be considered as a replacement for thermoplastic foils showing the same type of wood grain effect.
