Why Some Window Films Turn Purple But Ours Don’t

Our 3M Window Films do not turn purple or fade over time and we back each installation with the 3M Guarantee which gives you a full coverage warranty.

What Causes Other Window Films To Fade Or Change Color?

Many low-quality window tints and window films will begin to fade and change into a purple color over time. This is typically seen in auto window tint, however, it is seen in architectural grade window films that are from non-3M brands.

Experts state that the harmful UV rays window films are used to block can lead to failure in the dyes used by many low-quality window films. When dyes used to tint the window film are applied after the UV coating. Manufacturers who cut corners to lower production costs ultimately create an inferior quality product which is why it’s better to call the professionals here at Suncoast Window Films to get the job done right the first time.

Why Does Some Window Film Turn Purple?

You now know that poor manufacturing and inferior window films lead to discoloration, but what exactly makes the film color change to purple? The purple color is due to the red and blue dyes in the film bleeding through and combining which takes the form of a visible purple discoloration.

Choose The Professionals You Can Rely On

Window films are dyed to get the desired level of darkness, however, cheaper low-quality films often have the dye placed over the UV protection leading to a lot of undesirable issues. Over time these issues lead to less protection from the sun and unwanted purple discoloration making windows unpleasant to look at. Avoid the hassle and waste of money by hiring the professionals here at Suncoast Window Films.
