Using nano-technology, 3M is able to create ceramics so fine they are not only invisible to the naked eye, they’re imperceptible with an ordinary microscope. The result is a film that is tough, won’t corrode and enhances your view with greater clarity. Unlike other high-performance films that can corrode and often change colors on the edges, the Ceramic Series retains its color and appearance and will continue to look good over time. Improving comfort, protecting vehicle interiors and blocking UV rays are hallmarks of 3M™ Automotive Window Films. 3M was issued the first sun control window film patent in 1966, and our innovative window film products have helped provide protection from the sun’s harmful rays for 50 years.
