Copter Exoglass for Samsung Galaxy S21 - flat edition Copter Exoglass protects your touch screen against all the small mishaps of everyday life and make sure that your device always looks new by preventing the onset of scratches. Copter Exoglass is a four-layer screen protector consisting of materials used in the manufacture of protective glass in the defense industry. The main component of the screen protection is a thin layer of optical glass that is chemically hardened at the molecular level. This type of glass has a technical hardness comparable to steel. The inner side of the glass is reinforced with a PET film containing a layer of adhesive silicone material. The grease-repellent surface treatment on the outside of the glass prevents the appearance of fingerprints. Composite material in the protective glass has a large number of important properties that, for example, contribute to improved optical properties, a high mechanical strength, resistance to tremors and sharp temperature reductions, as well as moisture resistance and chemical stability. The material also effectively protects against external influences by absorbing the impact of shocks and blows. Copter Exoglass's operating properties work together to ensure reliable protection for your touchscreen, even under extreme conditions. This means that you can save money by not having to replace the touchscreen and/or original glass. This is not an edge to edge protection i.e. a few millimeters is not covered by the protection. This is also called "case friendly" as this type is well suited if the product is used together with shells or cases.
