For even more scratch-resistant matt surfaces.
An interesting alternative to the classical matting processes is physical matting with so-called excimer UV rays. In this innovative method, the liquid UV-curing excimer coating "Innolux Topcoat EXC" applied in the rolling process is irradiated with short-wave UV light (172 nm) in the absence of oxygen. This leads to superficial polymerisation, which causes volume shrinkage, which in turn manifests itself in surface folds of varying degrees. This deformed "skin" leads to a diffuse reflection of light, which we perceive as a matt effect. For complete curing of the coating layer, it is irradiated immediately afterwards with a UV dryer.
