Coated scratch-resistant glass represents the largest and most technically sophisticated segment of the market, leveraging advanced deposition technologies to apply thin films that dramatically enhance surface hardness and durability without affecting optical clarity. These coatings are applied through processes such as magnetron sputtering, chemical vapor deposition, and sol-gel techniques, creating protective layers that resist abrasion, chemical attack, and environmental degradation.
The technology behind coated scratch-resistant glass has evolved significantly in recent years. SCHOTT uses magnetron sputtering and its own proprietary process for hard anti-reflective coatings, resulting in both scratch resistance and anti-reflective characteristics. The result is a broad-band anti-reflective coating that shows significantly higher scratch resistance—from about 10 to 1000 cycles in Taber-abraser testing—and doubled hardness exceeding 20 GPa. These advances are enabling coated glass to maintain optical performance while withstanding the rigors of daily use in demanding applications.
Recent innovations include the development of sapphire coatings deposited on various substrates, including glasses, metals, and plastics. The hardness value of these sapphire coatings exceeds 8 on the Mohs scale, making them ultra-hard and highly scratch-resistant. Additionally, aliphatic polyurethane acrylate combined with modified titanium dioxide has been used to create cover glass coatings that balance impact resistance and scratch resistance while improving weather resistance and self-cleaning performance.
The coated glass segment is benefiting from the growing demand for anti-reflective, anti-fingerprint, and easy-to-clean surfaces in consumer electronics and automotive displays. As device manufacturers continue to push the boundaries of display performance, the demand for advanced coating technologies that deliver both optical excellence and surface durability is expected to grow substantially.
