Falling ball test 2X shatterproof Glass :

By a 64G ball dropped on the center of the tempered glass screen protector from the top of 120 cm-150 cm, after 3 times, no broken.

Ion exchange Mechanism of 2X shatterproof Glass

The k+ have a larger diameter than the Na+ and exert compressive stress on the glass surface.

Compressive Stress of 2X shatterproof Glass

When large-diameter K+ change places with small-diameter Na+ on the face of a glass sheet, the larger ions are squeezed into s small space.

Bubble Free & Dust Free

In order to save costs, many factories produce in a non-dust-free environment, and it is easy to absorb dust into the product AB glue, and some dust is difficult to be found if it has not undergone strict quality inspection after production, until they are attached. You can see it on the phone, it's too late.

Some factories use low-quality AB glue, and air bubbles may also appear.

OTAO adopts high-standard quality inspection procedures, from raw materials, production environment, production process to final storage, strictly controls, and delivers a qualified dust-free and bubble-free tempered glass screen protector to you.

Delicate Smooth Oleo-phobic Coating Treatment

The fingerprint problem is really annoying because it reduces the visibility of the screen. In addition, there are problems such as water spraying and dripping oil, which make the situation worse.

But these things don’t happen in OTAO tempered glass screen protector.So the typing and touching the phone surface are much easier and hassle-free.

We use plasma spraying and electroplating processes to evenly spray the fingerprint oil imported from Japan on the glass film to achieve a lasting hydrophobic, water- and oil-repellent effect.
