The vastness of the territory and the diversity of the terrain have made nature a miracle. Forests, snow-capped mountains, lakes, grasslands....those places that are like a "fairyland on earth" make people linger. But there are also some risks hidden behind the beautiful scenery, especially for the residents who live in those places, high latitudes, high ultraviolet rays and extreme climatic conditions can not only cause some damage to the human skin, but also to the body of the car.

Exposure
Exposure to the sun for a long time will cause great harm to the car paint, which will accelerate the aging and fading of the car paint, make the car lose its original beautiful luster, and affect the life of the car paint.

Ultraviolet
In the four seasons of the year, autumn and winter are the seasons with the least ozone layer content, so the damage of ultraviolet rays to car paint is particularly strong, ultraviolet rays will destroy the molecular structure of the base paint, so that the pigment precipitates out of the free resin, causing the color paint layer to fade!

sleet

The snow will melt into water when it falls on the car paint, and then the snow will accumulate more and the lowest layer of water will condense into ice, and the formation of ice on the car paint will cause serious damage to the car paint, and it is difficult to remove. On the other hand, when traveling on a sunny day after snowfall, a lot of mud and snow splashes on the car body, causing damage to the car paint in the sun!

microtherm

The low temperature environment makes the paint surface of the car more brittle, and it is more likely to crack after being hit! The stones and ice on the side of the road are not, they are harder in the low temperature environment, so the stones and ice on the side of the road are more likely to damage the car paint when driving in low temperature in winter, and even small stone particles can damage the car paint and produce cracks under high-speed movement!
The paint protection film system adds an almost invisible layer of protection to the car body and is increasingly popular with car owners today. Paint protection film systems for vehicle paints include adhesive layers, base films, top coats, and protective liners for new exterior surfaces.
Made by the reaction of polyols, chain extenders and diisohydrothalates, TPU is an environmentally friendly polymer elastomer that can be used in a wide range of applications, alternating between soft and hard segments, giving TPU rich chemical properties. It has excellent comprehensive properties such as high strength, high toughness, high elasticity, high modulus, as well as chemical corrosion resistance, wear resistance, oil resistance, and strong shock absorption ability.

The inherent physical and chemical properties of TPU make it an ideal product choice for the manufacture of paint protection films. In order to ensure the longevity of the paint protection film and maintain the appearance of a transparent and high-gloss finish, the base film with aliphatic polycaprolactone thermoplastic polyurethane (TPU) has obvious advantages. adoptDesmopan UP TPU from Covestro® The estimated product life of the paint protection film is 5-10 years, and the estimated life of the PVC protective film is only 1-2 years.
Creating a high-performance automotive paint protection film application also requires an in-depth application of the material properties of TPU to achieve stable raw material performance, and the balance between processing technology and adaptation to increasingly challenging use cases.
