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.
