3mk HardGlass™ Tempered Glass

HardGlass™ has a 9H hardness.

This is the highest level of scratch protection. Even sharp objects like knives or keys are no longer a threat.

Top quality finish and durability.

HardGlass™ owes its strength to hours of tempering at a temperature of 420°C.

Comfortable use thanks to the 2.5D rounded edges.

The improved production process and the 0.3 mm thickness enhance impact protection.

Excellent color transmission

Yes, it’s true – HardGlass™ has a multi-layered structure. The challenge was to ensure all layers are appropriately transparent. We accepted the challenge. The selection of high-quality coating components guarantees perfect color reproduction on the screen.

The new oleophobic layer in HardGlass™ provides even better touch experience.

Do you want to make sure that the tempered glass won’t affect the touch fluidity? The oleophobic coating ensures excellent glide, and you won’t feel any difference between using the device with and without the glass! The oleophobic layer also helps to keep the screen clean.

The coating has a higher resistance to oily stains, acids, and other corrosive substances, making it easier to remove them from the surface of the glass.

Perfect color reproduction is thanks to the perfectly clear, multi-layered structure of HardGlass™.

It does not discolor, thanks to its properties remaining unchanged throughout the entire usage period.

Easy installation and perfect touch sensitivity all the way to the edges, made possible by the non-sticky Inviscid-Sil™ substance.

Full screen responsiveness

Delayed response time to finger touch? There’s no such thing; we’ve taken care of that! The glass adheres so perfectly that there are no distortions or delays. Every finger movement on the screen happens in real-time! Simply full responsiveness!

In HardGlass™ the density and adhesion properties have been additionally increased, reducing any micro-disturbances between the glass layer and the screen.

Reinstallation and removal have been made easier thanks to the protective layer on the top side of the glass.

Moreover, it keeps the glass in perfect condition during transport and storage.

The production process of HardGlass™ is compliant with standards and environmentally friendly.
