HardGlass toughened glass Samsung A34 5G A346 HardGlass has 9H hardness. This is the highest protection against scratches. Even sharp objects like a knife or keys are no longer a threat. Top quality finish and durability. HardGlass owes many hours of hardening at 420°C. Comfortable use thanks to rounded edges made in 2.5D technology. Improved production process and thickness 0.3 mm strengthen impact protection. The new oleophobic layer in HardGlass gives an even better touch experience. It provides extremely smooth and pleasant slip. The coating has a greater buoyancy of fatty stains, acids and other corrosive substances, making it easier to remove them from the surface of the glass. Perfect reproduction of displayed colours is due to the perfectly clear, multilayered structure of HardGlass glass. It is not discoloured due to its unchanged properties throughout the lifetime. Easy installation and perfect sensitivity to touch up to the very edges possible by the use of a sticky Inviscid-Sil substance. HardGlass additionally increased its density and adhesion properties, reducing any micro interference between the glass layer and the screen. Any reassembly and dismantling was facilitated by the layer protecting the top side of the glass. In addition, it keeps them intact during transport and storage. HardGlass glass production is compatible with standards and environmentally friendly.
