With the continuous development of technology, the automotive maintenance market is also rapidly rising. In this new era of pursuing perfection, car owners have increasingly high requirements for the maintenance of their cars. As a brand new car maintenance product, invisible car clothes have won the favor of many car owners with their unique characteristics and advantages. So how is the invisible car cover (also known as paint protection film) produced to protect your precious factory paint? Today, the editor will take you to explore the truth!

From TPU masterbatch to TPU original membrane

The original form of paint protection film is just a small TPU masterbatch, which is a non stretching, non directional extruded TPU original film produced by rapid cooling of molten saliva. Generally speaking, if you choose the right TPU particles, a good film becomes the majority. For example, Motan PPF, an imported polycaprolactone based aliphatic TPU substrate, has good stretchability, scratch resistance, and wear resistance, providing excellent protection for car paint.

Back glue process
With the TPU film surface, the next step is to use composite adhesive. The adhesive process of the film is the same as the principle of spray painting, which requires spraying primer before spraying colored paint. The same goes for the back glue, which is applied to the film surface of the TPU substrate through the coating process.
Coating process
Coating technology can be said to be the core competitiveness of various paint protection film brands. Many properties of paint protection films, such as corrosion resistance, stain resistance, and automatic repair, are all attributed to coating technology. This is also an important technology that widens the gap between different brands and determines the brand's position and price.
The so-called coating process, in simple understanding, is like nano crystal plating on the surface of the film, which adds a layer of nano repair coating material on the TPU substrate, equivalent to adding an additional layer of protection. Motan PPF has excellent mechanical strength, oil resistance, chemical resistance, wear resistance, and tear resistance, with excellent comprehensive performance.
Finished product cutting
When the above process is completed, it is already a finished film. Special identification such as watermark logo and warranty roll code number should be printed, and of course, labeling and packaging into boxes are necessary. Finally, it should be stored and registered, waiting for different vehicle models to be cut and constructed.
