1 UV LED Curing for Wood Coatings By Mr Robert P Karsten, BSc Mech. Eng., MBA, Director of European Sales, Phoseon Technology Abstract The paper undertakes a critical evaluation of implementing UV LED technology for curing wood coatings. In particular it will discuss water borne UV applications and assess the benefits of the technology from an environmental and carbon foot print perspective. It will also discuss the performance criteria for a fully UV LED curable wood coating system in terms of its technical performance. And also look at the economic impact of the total solution/system. The aim of the paper is to demonstrate that UV LED technology and compatible coatings can greatly reduce the environmental impact and carbon foot print of wood coating processes without compromising on coating performance. Introduction There are many drivers that keep the interest in moving to UV curing active such as reduced operating costs, higher productivity and a more environmentally friendly solution which more and more end customers are demanding. As manufactures are developing UV curing systems, knowing how the key sub-components work together will help in creating the optimum system and thereby reducing the overall environmental impact of the process and at the same time maintaining or improving productivity and product performance.
