3M™ Automotive Window Film Crystalline™ Series features multilayer optical film and ceramic nano-technology that rejects more heat than many darker films without changing the car's appearance. Crystalline Series allows you to have a lighter tint and still reject high amounts of heat - the highest of all 3M films.
3M™ Automotive Window Films Crystalline Series, patented multilayer and metal free nanotechnology optical films, have more than 200 layers in what is less than the thickness of a Post it Note®. This technology is the reason a virtually clear film can reject more heat than darker films. They provide a high performance combination of high visible light transmission, low visible light reflection, with high heat gain reduction capabilities. The films block almost the entire range of UVA and UVB rays which are a main cause of fading and skin damage. All products of this family have the German ABG clearance.
