TPU car clothing film production line manufacturers introduce the reasons for the yellowing of invisible car clothing, let's learn together!

         The manufacturer of the TPU car clothing film production line stated that due to technical limitations, the density of the top coating of the first generation of invisible car clothing is not enough to resist small external substances from invading the TPU substrate. Therefore, the first generation of invisible car clothing needs to undergo regular film maintenance. This maintenance actually involves applying hydrophobic car wax to the surface of the film, blocking the capillary tubes on the top coating through car wax, in order to prevent external substances from penetrating the top coating and invading the TPU substrate. If there is a lot of rain or after washing the car several times, this wax will fall off and lose its protective function, making the invisible car coat easy to get dirty. If not treated in a timely manner, when foreign objects penetrate the bottom layer of the film, the film will lose its luster and turn yellow.

         The technological revolution of the second generation of invisible car clothing:

         The manufacturer of the TPU car clothing film production line stated that the second-generation invisible car clothing has made significant improvements on the basis of the first generation. Firstly, the TPU substrate has undergone molecular re crosslinking treatment, resulting in an increase in the density of the TPU substrate and a reduction in the gap between molecules, thereby enhancing the physical properties of impact resistance. In addition, the top coating has also been changed to use TPU material. The bonding between the top coating and the substrate is stronger, and the top coating also adopts molecular re crosslinking technology, resulting in a higher density of the top coating, reaching a nanometer level below 0.0001mm, thereby resisting almost all foreign object invasions in daily environments, ensuring that the invisible car jacket remains moist, clean, and shiny. At the same time, due to the dense nano top coating, the second-generation invisible car suit also has a long-lasting mirror effect and long-lasting hydrophobicity. The customer's intuitive experience is the hydrophobic effect of the second-generation invisible car jacket. Every time it rains or washes the car, the body is covered with pearl like lotus leaf water droplets. After washing the car, it is very bright, even brighter than waxing.

         TPU car clothing film production line manufacturer: Second generation invisible car clothing iconic features:

         1. Nano level top coating;

         2. High density TPU substrate;

         3. Compared to the first generation, the second generation invisible car suit has the following advantages:

         1) The top coating is denser, the surface is smoother, more mirror like, and brighter;

         2) The substrate is denser, with higher hardness and stronger impact resistance;

         3) Has stronger anti fouling ability;

         4) There is no orange peel phenomenon;

         5) Stronger hydrophobicity, less prone to rain spots;

         6) There is no need for waxing to encapsulate the top coating capillary, waxing is only for cleaning purposes;

         7) The top coating is also made of TPU material, which is more firmly combined with the substrate and does not peel off. The top coating is also added with UV resistant polymer to provide extra protection for the paint surface.
