New Methods for Matting of 100% UV-Coatings

Radiation-curable coating systems are gaining ground in an increasing number of applications, thanks to their favorable emission behavior. The most important market segment in Europe is the wood coating sector with over 14%. Matted coatings, varying from very dull to satin gloss, dominate in the wood and furniture coating sector. The matting of 100% UV coatings still presents a major challenge to every paint technician, whereas the matting of solvent-containing or aqueous coatings poses no problem 11. The problems are due to the virtual absence of film shrinkage in the 100% UV coatings during the curing of the system.
