Q: What Causes Film To Turn “Purple”?

A:  Years ago, colors such as “bronze” or “smoke” in window film were achieved by adding a dyed layer of film to a base product.  Over the years the ultraviolet light and sun leeched the lighter colors out of the dyed layers; leaving the “base”, or darker colors. Many bronze window films turned a deep red, smoke films tended to turn purple. Some films today still have dyes in their adhesives to impart a certain color.

Most quality window films these days are manufactured without the use of dyed laminates. While dyed films are still manufactured today, we rarely showcase them, and don’t recommend them for long-term use. If you have any doubts about products you have been shown, ask the sales representative specifically if his products incorporate the use of dyes.
