Can the film really block more than 99% of ultraviolet (UV) radiation?
A. Most window film companies infuse UV inhibitors into the adhesive part of the film, not into the film itself. Compared to UV inhibitors added into the structure of film itself, these kind of inhibitors have very low durability. Life Guard Films have the UV inhibitors added to the structure of the films, and even after being exposed for 2,000 hours in a xenon accelerating test room, 99% of the UV radiation was blocked. Although it actually depends on where to install a film, but this test is assumed to be equivalent to approximately 3 – 5 years exposure in a standard environment. Even after the product of other companies have lost their ultraviolet ray prevention effect, Life Guard Films will still be effective.
