Waterborne UV-curing parquet coatings – The environmentally friendly way to a perfect parquet surface


For industrial parquet applications, UV-curing polyurethane dispersions are particularly recommended as they combine the high quality polyurethane properties with a fast and economic UV curing step. While the advantage in productivity used to be the main driving force in the past, an even more increased interest can be observed due to the worldwide efforts limiting emissions of volatile organic compounds.
