TARİX: 2022-12-16

Car PPF sarıIng, refers to the transparent PPF filmi exposed to natural light, ultraviolet, heat, oxygen, chemical erosion, water and so on the environment, as well as improper production process caused by the car color yellow phenomenon.

The second possibility of transparent PPF yellowing: glue

The glue ofƏMFhas strong exclusivity, and the glue specially developed for automobile paint and TPU substrate needs to be used. The color of glue shall be transparent, with stable weather resistance, and not easy to react with automobile paint and TPU substrate. Non directional development glue can never be used as automobile protective film. When it reacts with car paint and TPU substrate, it is very easy to cause TPU yellowing. If it has penetrated into TPU substrate, irreversible results will occur.

Less possibility of yellowing: coating

TPU coating refers to a layer of transparent material applied on the surface of TPU substrate to enhance the performance ofşəffaf avtomobil büstqalteri, so that the automobile protective film can effectively cope with the complex climate and environment in nature. In daily use of the vehicle, dirt such as dust, rain, bird excrement, iron powder and so on adhere to the film surface and penetrate into the TPU substrate under the effect of time, which will make the film surface hoarse and lose luster, and also present a yellowing state from the naked eye, but in fact, this situation is mostly pseudo yellowing, not directly caused by the coating.
