Anti-Fingerprint Glass
Anti-Fingerprint Glass is a glass designed to prevent fingerprints by increasing and maintaining the surface tension of water droplets in contact with the glass by wet and dry coating on the surface of the glass, thereby forming a thin film of water on the surface of the glass to prevent fingerprints from sticking to the surface of the glass as well as easily removing other organic contaminants by lowering the bonding strength of the surface of the glass.
