9H 3mk HardGlass? glass for iPad Air 4 / 5 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. Uup is an
improved manufacturing process and 0.3 mm thickness enhance impact protection.
The new oleophobic coating in HardGlass provides an even better up-to-date touch
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 ideal
sensitivity to touch right up to the edges are possible thanks to the use of the
non-sticky substance Inviscid-Sil. In HardGlass up, 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.
