What Causes Blurry Window Tint?
What Causes Blurry Window Tint? There are two types of blurry tint, one will go away in a few days, the other is a whole different animal. Learn more below.
After a tint job, motorists will often experience cloudy or blurry windows. This is very common problem. Autobahn technicians are trained to ensure that your window tint is perfectly installed from the moment you pick up your vehicle. Even still, there may be a bit of haze on your windows for the first few days. Here is why it happens, and what to expect after your tint job is complete.
Climate and Window Film Installation
With traditional installations this is completely normal and temporary. For the first few days after your windows are tinted they might appear cloudy, hazy, and you may see little water pockets forming underneath the film. When windows are tinted, the squeegee can only remove a certain amount of the water from between the film and the glass. As the film dries, the remaining water may form little bubbles. Window film is a porous material that allows water to evaporate, so these water pockets will simply evaporate and go away by themselves as the film fully cures to the glass. The amount of time before your new tint will be totally dry is determined by the skill of the installer, the amount of sunlight it gets, and the type of film chosen. If it’s cloudy and overcast outside, it will take longer, if it’s hot and sunny, then the film dries very quickly. With a typical installation this could take anywhere from 3 days to one week. In the winter you can expect this to take a bit longer because of the moist cool air slowing down surface evaporation.
Two Types of Haze
Installation Haze: Installation haze is what is described above. Tiny molecules of water are trapped between the film and the glass and evaporate over the course of a week or so. This effect can be minimized by spending extra time with a heat gun during application, or making a few extra passes with a squeegee during installation. Give it a few days and your windows will be perfectly clear, just as expected.
Tip: Avoid any extra stress on your windows during the curing period, this includes rolling the windows up and down. You are best to leave them closed until the films are fully cured.
Low-Angle Haze: Low-angle haze is a completely different sort of blurriness altogether. This type of haze refers to a fuzziness in the windows that is only visible when looking at a steep angle through the glass such as a windshield or a side window in front of you. This is not seen in all films, but it is visible in some ceramic “nano dispersion” films. To create a ceramic film of this type, the polyester film is surface coated in a solution with tiny particles of ceramic. If you were to look at them under a microscope you would see that they are not completely round, they are actually more of a pebble shape. That means that when light hits them at a very low angle there is a slight disruption in the light transmittance that causes a blurry effect.
Tip: To combat this problem, you should consider going with Hüper Optik Ceramic films. Where traditional blends cause low-angle haze, Hüper Optik Ceramic’s particles are “sputter coated”one titanium nitride molecule at a time forming more of an organized structure than the random orientation of a “dispersion” film.
