One of its selling points is the self-healing ability of the invisible car clothing. After the film is applied, the car can recover itself when it is scratched. But there is a prerequisite for this self-healing.
1. Material - TPU
The function of scratch repair is only available for the invisible car coat made of TPU. TPU, English: thermoplastic polyurethanes, the name is: thermoplastic polyurethane elastomer rubber. This material has a characteristic, that is, it is particularly elastic, and the fission elongation is greater than 50%. It is a polymer material with very good recovery after the external force is removed.
The principle of scratch self-healing of TPU stealth car coat is as follows: when a TPU stealth car coat is cracked by external force, and the external force is withdrawn, this TPU molecule will undergo fission and elongation. Of course, high temperature can promote or accelerate the occurrence of this effect to a certain extent, so as to achieve self-healing.
2. Temperature - normal / high temperature
Normal temperature usually refers to the temperature of 23 ° C. at this temperature, only the fifth generation TPU stealth car clothing (automobile paint protection film) can realize self-healing function. Although some people have tested that the fifth generation TPU stealth car clothing can also have slow self-healing function even at 0 ° C, they have not claimed low-temperature self-healing.
Due to technical barriers, the fourth generation TPU stealth car clothing is still the main one in the market. The temperature for self-healing function needs to be between 60 and 85 ℃, and too high will damage the repair coating factor. As we all know, in hot summer, the temperature of the exposed car body is far higher than 60 ℃. Anyway, there is no need to worry about the repair temperature. Therefore, many brands of stealth car clothing take the opportunity to vigorously publicize that their brands have normal temperature self-healing function.
Therefore, the fifth generation stealth car clothing made of TPU material has good self repairing ability at normal temperature or high temperature.
