Matting by means of Excimer technology
At a wavelength of 172nm, excimer lamps have an enormously high-energy emission that starts a polymerization process in the uppermost part of a layer of UV-curable coating. The final ring depth of the UV emission is comparatively low, so this process leaves a thin film on the wet coating without affecting deeper layers of coating. Since this film formation is subject to shrinkage, the film near the surface exhibits micro-folds, resulting in a matte surface. These can be cured in the final cure using conventional LAMPcure technology. The result is a mechanically and chemically highly resistant surface.
