Three causes and solutions for fogging of paint protection film

After pasting the invisible car clothing for a period of time, it is found that the clarity of the car clothing that should be high-definition and translucent is reduced, and it looks foggy, which is collectively referred to as fogging.

Three causes and solutions for fogging of invisible car clothing

Note: "Fogging" and "pollution" are two concepts, fogging is generally a manifestation of physical phenomena, and pollution focuses on the manifestation of chemical phenomena.

So why does the invisible car suit fog up? Once fogging occurs, is there a way to fix it? Today, Xiaobian will give you a detailed answer to several possibilities and solutions for car clothing fogging!

1. The residual moisture after the film is not evaporated

As we all know, the invisible car clothing is constructed by wet paste, so there will inevitably be moisture residue. The mist between the paint and the film created by this unevaporated water will make the clothing visually foggy.

Solution:

For the fogging caused by the residual water after the film is not evaporated, you only need to wait for the water vapor to dry completely, and this process is about 7~10 days after the film. If there is a lot of residual moisture during construction, it will take longer for the car to dry completely.

2. Caused by improper film rolling

Like TPU invisible car clothing with high anti-fouling characteristics, the coating hardness will be relatively high, if the store master cuts the film, the coating surface is rolled on the inside when the film is rolled, causing the coating to fold on the surface, and the car coating will produce fogging phenomenon.

Solution:

In view of the fogging caused by improper film rolling, first of all, the technician must roll the coating surface on the outside when rolling the film, and cannot roll it back. If the fogging phenomenon has been caused by the reverse rolling, but it is found in time, it can be recovered by baking the gun and heating with hot water. (Note: If the treatment is not detected in time, the coating cannot be restored after the whole is cured.) )

3. Caused by improper construction

In the construction of some places with large arcs, if the technician stretches excessively, the force of the car clothing is uneven, and the local coating is destroyed, which will also lead to fogging of the car clothing.

(Overstretching can lead to fogging and loss of gloss of the coating)

Solution:

For the fogging caused by excessive stretching, the treatment is the same as above, and it can be recovered by thermal repair if it is found in time. Technicians need to pay attention to the fact that when encountering parts with large arcs during construction, such as bumpers, reflector corners, etc., do not overstretch and damage the coating, and keep the film surface and the paint surface fully lubricated, so that the film surface will be evenly stressed during stretching, and prevent local overstretching from causing fogging or loss of light on the film surface.
