9H 3mk HardGlass? glass on Xiaomi Redmi Note 11s / 11 4G 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 owed to 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 layer in HardGlass gives even better tactile
sensations. It provides an extremely smooth and pleasant glide. The coating has
greater resistance to greasy stains, acids and other corrosive substances, which
makes it easier to remove them from the glass surface. Perfect reproduction of
the displayed colors is due to the perfectly clear, multi-layer structure of
HardGlass glass. It does not discolor due to its properties remaining unchanged
throughout the entire period of use. Easier installation and perfect touch
sensitivity right up to the edges is 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-disturbances between the glass layer and the screen. Possible reassembly
and disassembly have been made easier thanks to the layer protecting the top
side of the glass. Moreover, it keeps them intact during transport and storage.
The HardGlass glass production process complies with standards and is
environmentally friendly. The components used to produce glass come from
Japanese suppliers.
