Question #1: What is meant by "outgassing" of a kapton label?Originally posted by Demlotcrew
I think its things like pollen, brake dust, diesel suet etc.
Anwer #1: We all love the smell of a new car...there's nothing quite like it. One year later...have you noticed the haze on the windows, even when you have never allowed ANYONE to smoke in your car? The lovely "new car smell" is an example of OUTGASSING, and the foggy window is typical of the long term effects, a haze deposited on surfaces. Many materials will emit gases under heat, such as the heat of the sun on the interior of your car.
These "volatile" materials are present in almost all polymeric/synthetic matertials, such as coatings, films, and adhesives. As heat is applied, the volatile organic compounds (or VOC's) evaporate from (in the case at hand) the polyimide or kapton label.The gaseous molecules are free to be redeposited on a cooler surface, such as a car window, mirror, or any other surface.
