The CG 4 series is an anti-reflective coating on one or both sides based on an optical interference coating for technical applications such as front panels of visual displays, touch monitors, televisions, display panels, public displays. The multilayer coatings are applied by means of a wet chemical process (sol-gel) in dip-coating technology. The glass substrate can be soda-lime, aluminium-silicate and ultra-white glass, etc. Wet anti-reflective glass is the only type of glass that can be chemically strengthened with anti-reflective coatings.
