This Tempered Glass is thick and made with high quality chemically treated transparent tempered glass. Break protection and shock resistance. The surface of the tempered glass has a hardness of 9H, three times stronger than regular PET film. The tempered glass has an oleophobic coating that prevents fingerprints and other contaminants and makes the film easy to clean. The tempered glass is coated on the back with a strong silicone adhesive that makes installation easy and attaches the film firmly so as to not affect the touch screen's sensitivity. If broken, the tempered glass breaks into small pieces that are not sharp, making it safer than other glass products.
