Varför gulnar bil PPF (2)?

DATUM: 2022/12/16


Bil PPF gulning, hänvisar till den genomskinliga PPF-filmen som utsätts för naturligt ljus, ultraviolett, värme, syre, kemisk erosion, vatten och så vidare miljön, samt felaktig produktionsprocess som orsakas av fenomenet bilfärg gult.

Den andra möjligheten till transparent PPF-gulning: lim

The glue ofPPFhas 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.

Mindre möjlighet till gulning: beläggning

TPU coating refers to a layer of transparent material applied on the surface of TPU substrate to enhance the performance ofklar bil-bh, 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.
