UV film is a type of tempered film. It is a special formula coating applied to the surface of PET, P0, PVC, EVA film substrates to achieve the effect of blocking ultraviolet light and short wavelength visible light. UV films are mainly suitable for optical etching processes or industries that require UV isolation during the process, such as semiconductor and electronics industries. To avoid poor product quality caused by improper light leakage. In addition, UV film is often used for tempered films on mobile phones, because compared to ordinary tempered films, UV film also has the effect of being resistant to falls and cracks< br /> The principle of UV film

Adding photoinitiators (or photosensitizers) to special formulated resins, after absorbing high-intensity ultraviolet (UV) light from UV curing equipment, generates active free radicals or ionic groups, which trigger polymerization, cross-linking, and grafting reactions, causing resins (UV coatings, inks, adhesives, etc.) to transform from liquid to solid within seconds (varying degrees). This process of change is called "UV curing".

The difference between fully adhesive tempered film and UV film

After multiple experiments, it was found that UV tempered film is the appropriate one. There are also differences between fully adhesive tempered film and water setting film. The hydrogel film can truly achieve comprehensive coverage of the screen world of mobile phones, with particularly good results, and the anti drop effect is better than this. With people pursuing the quality of mobile phones nowadays, there is an endless stream of new film replacements. But you need to buy inferior water setting or tempered film. It really doesn't work because it doesn't have that hardened and tempered side, such as heavy objects falling or flat falls, which can damage your phone itself.
