Samsung Galaxy Z Fold4 (Front) - 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.
