3MK HardGlass Sam A14 4G A145/5G A146 (5903108519502)

HardGlass™ has a hardness of 9H.
This is the highest protection against scratches. Even sharp objects like a knife or keys are no longer a threat.



Highest quality finishing and durability.
HardGlass™ owes it to hours of tempering at 420°C.


Comfortable use thanks to rounded edges made with 2.5D technology.
Improved production process and 0.3 mm thickness enhance impact protection.

Exemplary color transmission
Yes, it’s true – HardGlass™ has a multilayer construction. The challenge was to ensure all layers were sufficiently transparent. We took on the challenge. The selection of the highest quality coating components guarantees perfect reproduction of the colors displayed on the screen.



The new oleophobic layer in HardGlass™ provides even better tactile sensations.
Want to be sure that the tempered glass won't affect touch smoothness? The oleophobic coating takes care of that. It provides excellent glide, and you won’t feel the difference between using the smartphone with or without the glass! The oleophobic layer also helps keep the screen clean.

The coating has greater repellency of greasy stains, acids, and other corrosive substances, making them easier to remove from the glass surface.
Perfect color reproduction is thanks to the perfectly clear, multilayer structure of HardGlass™ glass.



Does not discolor, thanks to properties unchanged throughout the entire usage period.
Easier installation and perfect touch sensitivity up to the very edges are possible thanks to the use of the non-sticky Inviscid-Sil™ substance.

Full screen responsiveness
Delayed screen response to finger touch? Impossible, we took care of that! The glass adheres so perfectly that there is no interference or delay. Every finger movement on the screen happens in real time! Simply full screen responsiveness!



In HardGlass™ its density and adhesion properties have additionally been increased, which reduces any micro-interferences between the glass layer and the screen.
Possible re-installation and removal has been facilitated thanks to the protective layer on the top side of the glass.

Additionally, it keeps it intact during transport and storage.
The production process of HardGlass™ glass complies with standards and is environmentally friendly.

Components used for glass production come from Japanese suppliers.
