The answer is silica in airborne dust, which has a hardness similar to quartz (Mohs 7). When you walk with your phone in your pocket, it will constant friction with the silica.

    The answer is silica in airborne dust, which has a hardness similar to quartz (Mohs 7). When you walk with your phone in your pocket, it will constant friction with the silica.

      However,  normal 9H Tempered film only Mohs 4 Hardness  like fluorite , if constant friction with the silica it can easy cause wear in the screen protector or screen.

These tiny scratches not only affect the user's experience when using the phone, but also reduce the protection of the screen.

These tiny scratches create weak points in the stress layer of tempered glass, which is what gives the protector its strength. When the phone falls, the immense impact force can cause the glass to crack along these scratches, reducing its protective performance. This can lead to the frequent need to replace the tempered glass or even the phone screen itself.

Sapphire coating, which is second only in hardness to diamond, mohs 7 level hardness provides unparalleled scratch protection and will not show minor scratches over time

manufacturing principle

In vacuum container , pure sapphire is heated to 2000 degree until molten. 10 thousand Volt arc converts sapphire into plasma, which is magnetically deposited onto glass, creating 500nm sapphire coating

      We are not satisfied with prevent scratches .we hire world-class chemistry experts develops new technology at the molecular level  , reinforce glass stress structure layer,Excellent protection for mobile phone screen ，the name of technology ---

 

                  Density Enhancement Technology 

density enhancement technology 

When larger potassium (K⁺) ions replace smaller sodium (Na⁺) ions during an Chemical reaction，Forming a denser glass structure creating a tighter molecular structure. This also increases the internal stress of the glass。 This process produces glass that is 3X times stronger than tempered glass. in impact test reach 50kg resistant . significantly enhancing glass strength and durability. 

However,  normal 9H Tempered film only Mohs 4 Hardness  like fluorite , if constant friction with the silica it can easy cause wear in the screen protector or screen.
