Why do we use the more costly etching process for frosted protectors?

Sandblasting process: tiny quartz sand particles are sprayed on the transparent glass by specific means to produce a matte finish effect.

Etching process: the surface of transparent glass is etched with specific chemical reagents to produce a matte finish effect.

The disadvantage of the sandblasting process is that it is difficult to achieve high quality and uniform spraying, and the quartz sand attached to the surface is more easily dislodged by external friction. Therefore, the frosted tempered glass may have the following two disadvantages:

1) the surface is excessively rough causing a serious loss of screen clarity and wear of the Apple pen tip;

2) the glass surface has almost no matte finish effect, resulting in the anti-fingerprint not lasting, or even failing to achieve the anti-glare and anti-fingerprint effect.

On the contrary, the etching process is a chemical reagent corrosion process, so the product quality is more stable. The matte surface effect of its glass surface is moderate, which can maintain good clarity and also achieve the effect of anti-glare and anti-fingerprint, and can reduce the wear and tear of the Apple pencil.

Important:

Its a mild matte finish. Although it doesnt have quite the same drawing-on-paper-feel as matte plastic protectors, the matte glass is much better than glossy glass. Most importantly it doesnt get scratched as quickly as a plastic protector and severely degrades the display quality.
