If you want to put a color change film on your car, you may learn about a phenomenon after going to the market and asking around. The warranty period of automobile color change film is divided into two ranges: one type of warranty of 2-3 years, and one type of warranty of 5 years (of course, there are longer warranties, but relatively few).
For the color change film with a warranty of 2-3 years, the store often adds such a sentence: "It is recommended to come to the store to tear off the film within two years after the paste." "
Why do people in the film shop say that? Xiaobian will take you to analyze the reasons today!
Because some car color change film is made of PVC material, PVC contains plasticizers, which will be precipitated from PVC at a certain temperature, and the film at the bottom of the adhesive layer will precipitate due to the separation of plasticizer and film surface, tearing the surface of the film, but the glue is directly left on the paint surface, which is the reason for the degumming phenomenon of the color change film.
For the color modification film whose raw material is PVC, the probability of such a problem is even greater.
Therefore, the reason why the store allows the owner to tear the film after 2-3 years is because of the fear of degumming.
If the parking environment of the car owner is relatively poor, such as long-term open-air parking, the service life of the product may be shortened. Of course, if the car environment is relatively better, the use time will be extended.
How does a high-quality color change film deal with this problem? For example, some car owners have electrostatic stickers to stick signs, without using glue, but it does not affect its stickiness.
The same is true for high-quality color change films, reducing or even not using adhesive, higher quality products, daring to promise a longer warranty period, and the products will not be degummed during the warranty period.
From this point of view, there are certain differences in the viscosity of the back adhesive of the automobile color change film, and the more viscous it feels, the worse the quality, which is worth noting.
Dingxin Films PPF reminds car owners that the adhesive of some products is pseudo-low viscosity, and the viscosity is low when the backing paper is torn, but the viscosity will be very large when placed in the air environment for one or two hours.
