Samsung Galaxy A40 - 3mk HardGlass™

HardGlass™ has a hardness of 9H.

This is the ultimate protection against scratches. Even sharp objects like a knife or keys are no longer a threat.

Highest quality finish and durability.

HardGlass™ is due to many hours of hardening at 420°C.

Comfortable use thanks to rounded edges made with 2.5D technology.

Improved manufacturing process and 0.3 mm thickness strengthen the impact protection.

New oleophobic layer in HardGlass™ gives an even better touch experience.

It provides an extremely smooth and pleasant gliding experience.

The coating has greater displacement of greasy stains, acids and other corrosive substances, making them easier to remove from the glass surface.

Perfect reproduction of displayed colors is due to a perfectly clear, multi-layer structure of HardGlass™.

It is not subject to discoloration, thanks to its properties that remain unchanged throughout the entire period of use.

Easy installation and perfect edge-to-edge touch sensitivity are made possible by the non-stick substance Inviscid-Sil™.

HardGlass™ additionally increases its density and adhesion properties, which reduces any micro-distortion between the glass layer and the screen.

Possible re-assembly and disassembly is facilitated by a layer protecting the top side of the glass.

It also keeps the glass intact during transport and storage.

The production process of HardGlass™ is standardized and environmentally friendly.

The components used to manufacture the glass come from Japanese suppliers.
