AF/AS coatings, meaning anti-soiling (AS) and anti-fingerprint (AF) coatings, are mainly produced by vacuum deposition of organic fluoride materials onto substrates such as glass and organic glass including PC, PMMA and PET. They give the surface water, oil, scratch, fingerprint and contamination resistance. Hydrophobic coating is a new development that can be added to coated glass to create water-resistant optics. Bonded to the glass, it forms a barrier against contamination, dust, grease and liquids. The coating is non-acidic and allows glass to be wiped clean without cleaning liquid, making this water-resistant glass coating particularly suitable for touchscreens.
