Carro PPF amareloing, refere-se ao filme PPF transparente exposto à luz natural, ultravioleta, calor, oxigênio, erosão química, água e assim por diante no meio ambiente, bem como processo de produção impróprio causado pelo fenômeno amarelo da cor do carro.

A segunda possibilidade de amarelamento transparente do PPF: cola

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.

Menor possibilidade de amarelecimento: revestimento

TPU coating refers to a layer of transparent material applied on the surface of TPU substrate to enhance the performance ofsutiã de carro transparente, 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.
