Friends who have some knowledge of window film will advise: window film with low price would rather not be pasted. In fact, it refers to a part of inferior window film in the market, which seriously affects human health, and this kind of product is currently flooding the automobile market. We list the six major hazards of inferior window film.

Most of the thermal insulation coatings of inferior window films use cheap chemicals, which can absorb heat or insulate heat through chemical reaction with heat sources. During this process, strong but undetectable volatile gases, such as formaldehyde, will be released, resulting in odor in the car. Especially when the old film is torn off, the odor will be released in large quantities, which is extremely unpleasant. Such harmful gases are harmful to the elderly, pregnant mothers Newborns can cause great harm.

 

The thermal insulation of inferior window film is a chemical reaction. The cheap raw materials are used, and some construction problems will occur. Therefore, with the passage of time, small bubbles will appear between the film and the glass. Over time, the bubbles will become larger and larger, and the film is also very easy to appear discoloration, degumming, curling, scratches and other conditions, affecting the overall beauty of your car.

 

The uneven process of inferior window film is very easy to cause light refraction and random reflection. Looking out from the car, there will be a misty feeling, and even visual dislocation and deviation, resulting in excessive fatigue of both eyes, and even serious traffic accidents, seriously endangering life safety.

 

The poor window film has no resistance to heat transmission, or has good heat insulation effect in a short time, but the heat insulation layer loses its heat insulation effect after a long time of use, and the heat insulation performance is greatly reduced in large quantities, and the heat is transferred to the vehicle for a second time to form a vicious cycle. Instead, it makes the carriage hotter and hotter.

 

In order to save costs, the inferior window film adopts the method of adding infrared absorbent in whole or in large quantities, and the heat is absorbed on the glass, resulting in the high temperature of the glass. If it encounters thermal expansion and contraction, it will cause the glass to burst, adding many unnecessary troubles.

Because the adhesive layer used for the inferior window film is particularly cheap, and the longer it takes, the more difficult it is to tear it off, so it will cause great trouble when tearing it off. The film can only be torn off bit by bit, or there is a large amount of adhesive layer left. If it is not handled in time, the glue will stick to the glass more firmly, and the self-adhesive removal will have the risk of damaging the car glass. In addition, the whole car film removal also needs to take a large amount of time, Some of them are in poor condition, even for several hours, so the cost is not low.
