3M clear film technology.
The Crystalline Series features a proprietary, multilayer optical film nano-technology that combines over 200 layers in a film that is thinner than a Post-it® Note. This unique technology is the reason a clear film can reject more heat than darker films. Thin film technology is a core competency at 3M, and the multilayer film technology we incorporate in our newest window film is similar to those 3M developed for use in a range of trusted products found in your home or office.
