3M™ Color Stable's appearance rivals tinted factory glass, never turns purple, and provides high heat rejection with no signal interference! 3M's revolutionary nano-carbon polyester provides an incredible look, amazing colour stability, and is non-metallised to ensure no signal interference.
While most other window film companies buy their polyester from someone else, 3M makes its own polyester. During this process, 3M patented a technology for producing its own nano-carbon polyester. This revolutionary and unique process, allows for maximum heat rejection without a metallised film, which can interfere with radio and satellite signals. It also gives our films a stylish look with outstanding colour stability. In fact, it's so advanced that in time-based tests, 3M Color Stable films never turned purple while conventional dyed films rapidly changed to a purple colour.These darker shaded films are designed to reject solar heat that is produced from visible light. Color Stable rejects up to 57% of the heat coming through your windows. Color Stable films also provide significant glare relief, allowing only 5% to 50% of the light into your car.NOTE: The law on auto tint varies by state. Please to go to the International Window Film Association to check your state's laws. Or, ask your dealer for films approved for use on vehicles.WARRANTY: Selecting 3M Window Films gives you piece of mind.
