Samsung Galaxy S23 5G - 3mk HardGlass? HardGlass has a hardness of 9H. It is the
highest protection against scratches. Even sharp objects such as a knife or keys
are no longer a threat. The highest quality finish and durability. HardGlass
owes many hours of hardening at 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 an even
better tactile sensation. It provides an extremely smooth and pleasant glide.
The coating has greater resistance to greasy stains, acids and other corrosive
substances, which facilitates their removal from the glass surface. The perfect
reproduction of the displayed colors is due to the perfectly clear, multi-layer
structure of HardGlass glass. It does not discolor, thanks to the properties
that remain unchanged throughout the entire period of use. Easy installation and
perfect touch sensitivity right up to the edges thanks to the non-sticky
Inviscid-Sil. In HardGlass, its density and adhesion properties have been
additionally increased, which reduces any micro-interference between the glass
layer and the screen. Possible reassembly and disassembly has been facilitated
by a layer protecting the top side of the glass. In addition, it keeps them
intact during transport and storage. The HardGlass production process is
compliant with standards and environmentally friendly. The components used in
the production of glass come from Japanese suppliers.
