Achieving Ultra-Low Gloss Coatings Through the Use of Excimer Technology

There is a continuing desire for the aesthetic of ultra-low gloss in coatings in nearly every market and across many different substrates. There has also been a renewed interest in excimer technology as the desire for lower and lower gloss levels increases. Excimer lamps produce energy in the VUV range. This short wavelength energy only cures the very surface of the coating. Shrinkage during this process causes the surface to wrinkle, which leads to a matte finish without the use of matting agents. This presentation will examine the technique of using excimer lamps to achieve ultra-low gloss levels and discuss the structure features desirable in an oligomer to take advantage of the technology.
