3MK HardGlass Sam A53 5G A536 (5903108466554)

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



Top-notch finish and durability.
HardGlass™ owes its quality to hours of tempering at 420°C.

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

Excellent color transmission
Yes, it’s true – HardGlass™ has a multilayer construction. The challenge was to ensure that all layers are adequately transparent. We accepted the challenge. The selection of the highest quality coating components guarantees perfect color reproduction on the screen.



A new oleophobic layer in HardGlass™ offers even better touch sensations.
Want to be sure that tempered glass doesn’t affect touch sensitivity? The oleophobic coating ensures that. It provides excellent glide, and you won’t notice the difference between using your smartphone with or without the glass! The oleophobic layer also helps keep the screen clean.

The coating has increased resistance to greasy stains, acids, and other corrosive substances, making them easier to remove from the glass surface.
Perfect color reproduction is due to the crystal-clear, multi-layer structure of HardGlass™.



It does not discolor, thanks to its properties that remain unchanged throughout its usage period.
Easy installation and perfect touch sensitivity right to the edges are possible thanks to the non-sticky Inviscid-Sil™ adhesive substance.

Full screen responsiveness
Delayed screen response time to finger touch? That's not possible, we made sure of it! The glass adheres so well that there are no disturbances or delays. Every touch on the screen happens in real time! Just full screen responsiveness!



In HardGlass™, the density and adhesion properties have been further enhanced, reducing any micro-disturbances between the glass layer and the screen.
Reinstallation and removal are also made easier thanks to a protective layer on the top side of the glass.

Additionally, it keeps the glass in pristine condition during transport and storage.
The HardGlass™ production process complies with standards and is environmentally friendly.

The components used in the production of the glass come from Japanese suppliers.
