3M Color Stable Automotive Window Films

80348664211809

3M has developed a patented technology for producing window film that incorporates a unique process not found in conventional films. 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 metal film layer, which can interfere with radio and/or satellite signals. It also gives our films a stylish look with outstanding color stability. In fact, it’s so advanced that in time-based tests, 3M Color-Stable Auto Film never turned purple while conventional dyed films rapidly changed to a purple color.
