3MK HardGlass Xiaomi Redmi 9

3mk hard glass.

Higher fracture toughness than other tempered glass. The bottom of the 3mk® HardGlass is enriched with an Anti-Crash anti-impact foil. This multilayer structure increases the resistance to cracking, similar to glued anti-burglary glass.

The oleophobic layer of 3mk® HardGlass is perfectly smooth, giving a tactile feel closest to using the screen itself. It also makes it easier to remove fingerprints from the surface of the screen.

3mk® HardGlass owes its properties to many hours of curing at a high temperature of 420 degrees Celsius.
