Glas.TR Platinum tempered glass from Spigen is a first-class product, with the highest level of sophistication, designed in collaboration with the Whitestone Dome company, market leaders in the case of UV films. The experience of both manufacturers in the treatment of glass, for more than two decades, has given today innovative concepts in the protection of curved screens. A patented method was used for installation, consisting of applying the adhesive and then curing it with UV light. The higher price compared to other foils available on the market is justified by the technological advance used in the manufacture of GLAS.tR Platinum glass . We do not recommend you to use the glass film without the protective cover. It is compatible with most of the covers available on the profile market. After dismantling, the film will not leave any traces on the surface of the screen. The film has a surface hardness of 9H, which is why it is extremely resistant to scratches even in direct contact with sharp objects (knives, keys). In addition, the glass film from Spigen is covered with a special nano-layer, which protects the screen against fingerprints. Attention: The package includes the UV lamp, for mounting the film!
