Luvvitt Liquid Glass is a cutting-edge super durable, completely transparent liquid screen glass protector that bonds to the glass of your device offering greatly enhanced scratch, moisture, and impact resistance. It's made of silica dioxide (Si02) which is essentially microscopic particles of glass suspended in a liquid solution. Completely harmless and invisible once applied with easy wipe-on DIY application, Liquid Glass fills in the imperfections of the screen and adds an additional layer of glass (does not fix or repair exiting crack or scratches). It's extremely scratch & shatter resistant and it increases the glass' strength to 9h hardness. It's unique formula blocks 80% y wave radiation. Liquid glass screen protector is intended to protect your device's screen against regular scratches that may happen with regular use. It will NOT make your screen completely shatter-proof or scratch-proof. It will only improve your glass' strength and increase the scratch resistance.
