9H 3mk HardGlass? glass on Redmi Note 12 4G / 5G HardGlass has a hardness of 9H.
This is the highest protection against scratches. Even sharp objects such as
knives or keys are no longer a threat. The highest quality finish and
durability. HardGlass is made from many hours of hardening at a temperature of
420°C. Comfortable use thanks to rounded edges made in 2.5D technology. Improved
manufacturing process and 0.3mm thickness enhance impact protection. The new
oleophobic coating in HardGlass provides an even better tactile experience.
Provides an extremely smooth and pleasant glide. The coating has greater
buoyancy against grease stains, acids and other corrosive substances, which
makes them easier to remove from the glass surface. Perfect reproduction of
displayed colours is due to the perfectly clear, multi-layered structure of
HardGlass glass. It does not discolour, thanks to its properties remaining
unchanged throughout the period of use. Easier installation and perfect touch
sensitivity right to the edges are possible thanks to the use of the non-sticky
Inviscid-Sil substance. In HardGlass, its density and adhesion properties have
been additionally increased, which reduces any micro-interference between the
glass layer and the screen. Any reassembly and disassembly is made easier by a
protective layer on the top of the glass. Moreover, it keeps them intact during
transport and storage. The HardGlass production process is compliant with
standards and is environmentally friendly. The components used to produce the
glass come from Japanese suppliers.
