Samsung Galaxy A54 5G - 3mk HardGlass? 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.
