Create illuminated signs with different colors for day and night with 3M&trade Dual-Color Film 3635. Our matte cast film is 140 microns thick and perforated at 15% of the film surface, with up to 7 years durability. It allows you to create special effects on illuminated signs by having one color during the day (not lighted) and another color during the night. By applying a 3M&trade Scotchcal&trade Translucent Film on the second surface of the sign, a specific night time color can be achieved when backlit. Available in white or black.,
