With the increasing number of middle and high-end cars on the street, people begin to pay attention to the protection of car paint. Every car owner wants to keep a brand new appearance all the time, which directly affects the driving mood and the preservation degree of the car. However, facing various tests of the external environment, this idea is not easy to realize. What are the killers of car paint? Physical rub, stone knock, scratch; Chemical acid rain, bird droppings, gum and other corrosion oxidation, have brought direct damage to car paint.

 

The appearance of "invisible car coat" provides a relatively feasible solution for car paint protection. However, because the products on the market are varied and mostly imported, consumers know little about it. Is the invisibility Cloak obvious? Does it come out of gum and bubble? Will it turn yellow? Can it be partially repaired? Is it worth Posting?

 

At present, the latest generation of "invisible car clothes" are all made of TPU materials, with special properties, such as yellow resistance, scratch resistance, self-repair and so on. Domestic TPU industry has overcapacity, is there an opportunity to enter this high value-added market? I hope this article can give you a more comprehensive perspective.

 

What is an invisibility Cloak?

 

First, let's take a quick look at what an invisibility cloak is. Its full name is Paint Protective Film, or PPF.

 

Early invisible car clothing is mostly PVC, commonly known as rhinoceros skin, is a pure hardness to protect the car paint material. PVC car film is generally thick, the construction is not easy to wrap, and prone to yellow, easy to residual glue, poor toughness, and unable to repair Huaheng, as a product has been nearly eliminated, in addition to the low price, almost useless.

 

Instead, PU material is soft, with strong toughness, wear resistance and weather resistance, and good tensile strength. After installation, it can insulate the car paint from the air, prevent acid rain, prevent oxidation, resist scratches, and protect the car paint for a long time. However, PU material has poor resistance to alkaline etching, which will gradually turn yellow and the scratches cannot be repaired.

 

At present, the best material of invisible car garment is TPU, which has a certain improvement compared with PU material. TPU is a thermoplastic polyurethane with all the advantages of PU, higher brightness and incredible scratch repair.

 

With TPU substrate, why is the performance gap so big?

 

Currently, there are many stealth car clothing products with TPU substrate on the market, but their performance varies greatly. They can be divided into the first generation OF TPU stealth car clothing and the second generation of TPU stealth car clothing, which mainly depends on the differences in technology.

 

First generation TPU stealth car garment

The first generation of TPU substrate stealth car garment has much better yellow resistance than PVC and PU material, but it will still turn yellow after several years of use, because of technical limitations. The top coating density of the first generation product is insufficient to resist the invasion of small external substances into TPU substrate. Therefore, the first generation of TPU stealth car clothes should be regularly cured with a film, and sealant should be applied on the film surface to isolate the invasion of air and acid rain on TPU substrate.

The second generation TPU stealth car garment

Based on the first generation, the second generation OF TPU stealth vehicle coat carries out molecular recrosslinking treatment on TPU substrate, which improves the density of TPU substrate and reduces the gap between molecules, thus improving the physical performance of impact resistance. For the molecular technology of TPU, each brand of invisible car garment has its own technology and product performance. In addition, the second generation of TPU stealth car coat has also been improved on the top coating, adopting the nanometer level of less than 0.0001mm, which can effectively resist almost all foreign matter invasion in the daily environment, and ensure the invisible car length time to maintain clean gloss. At the same time, due to the dense nanometer top coating, the second generation of stealth vehicle coat also has a long-term mirror effect, and has a lasting hydrophobicity. The owner of the most intuitive feeling is, every time it rains and wash the car, the body will be like lotus leaf hung full of water.



The development of the invisible car garment brand coating in China

 

Paint surface protection film originated in foreign countries, around 2010, the real domestic enterprises began to do automotive paint surface protection film. At present, the industry is some non-standard, development is also relatively restricted. It should be said that automobile paint protective film has been developed in foreign countries for more than 20 years and has been proved to be able to effectively protect the original automobile paint. Automobile paint protective film should also be able to develop rapidly in the Chinese market, just like the original glass explosion-proof film, which is generally accepted and recognized by the public. Why the current situation is not optimistic, mainly due to the following factors:

 

At present, there are two kinds of domestic automobile paint surface protection film market: one is imported paint surface protection film, and most of them are produced by foreign small and medium-sized enterprises. Due to the limitations of production scale and research and development capacity, product quality is unstable from time to time. In the domestic market, the sales price is high because the products are imported brands, causing consumers to be discouraged because of the price, leading to the import of invisible car clothing brand into a car maintenance luxury. Due to the characteristics of casting grade film, imported paint surface protective film has good ductility and is easy to construct. After construction, it has good weather resistance and will not shrink the edge in 3-5 years. Good glue and no residual glue. The other type is the domestic coating. It is mainly produced by several large domestic companies that do inkjet printing consumables. The invisible car garment only accounts for a very small part of the enterprise products, and most of them use calendering single-molecule PVC film. The quality of this coating varies a lot. The kind made by the better enterprises can be used for 6-12 months, with little trimming and resizing. Almost the kind of enterprise do may only use 3-6 months, edge and residual adhesive situation is more serious.

 

 

 

2, the market awareness and acceptance of low domestic consumers do invisible car clothing film, generally speaking, are some of the better cars, the sensitivity of the price is not very high. Generally speaking, it is the high-end line of consumers, their awareness and acceptance of the invisible car garment is relatively high. But the domestic mainstream of less than 300 thousand cars do not make a high proportion of invisible car clothing. Because now can't produce high-end domestic TPU surface protective film, but the import of paint coating and very expensive, posted a vehicle material cost is more than 10000, and contact clothing technical requirement is high, process is more troublesome, domestic construction enterprises are difficult to stick good commonly, can lead to the development of the market more difficult. In addition, the consumer to the lacquer surface protective film understanding is less, feel this kind of new product price is higher, at the same time worry to cause harm to oneself car paint.

 

Reasons why consumers choose invisible clothing

 

1. When buying and selling used cars, the value of painted cars is not high, so it is easy for buyers to suspect them as accident cars. The transparent coating can perfectly protect the original paint and enhance the brightness of the paint. It can also play a beautiful role.

 

2, prevent corrosion environmental pollution is increasingly serious today, car paint is bound to face acid rain corrosion and oxidation, and in daily life, the invasion of sand and stone collapse splashes, cut by branches is inevitable, even in autumn and winter season, falling on the car dew will cause corrosion of car paint. The transparent protective film is applied to separate the paint from the outside environment, and the above mentioned damage to your car is not to be worried about

 

Many drivers may have encountered a rowing party. A small number of them may have been driven by improper parking which obstructed the normal traffic to vent their anger. However, most of these parties commit their crimes at night without surveillance or by avoiding surveillance cameras. Even if they are photographed by the dashcam, most of them cannot be identified because of the poor function of the dashcam during the night. And go scratch danger for many times, can affect arrive year premium pay limit.

 

4, no longer worried about being borrowed luxury car is always eye-catching, but also the wedding car and the need to prop up the first choice of scene activities. And the general car is not a friend or colleague, borrow, worry about the car is ruined; If I don't, I won't get over it. Coat your car with a clear coat of paint to add a protective barrier. Transparent car paint protection film is the ultimate solution for car paint maintenance. Compared with traditional waxing and sealing glazes, transparent car paint protection layer has better protection effect and does not hurt the car paint, which can achieve long-term and continuous protection effect. Posted after the car paint surface protective film transparent body appearance does not change, it may be difficult to find, to the naked eye only increased the brightness of the paint and gloss, like invisible escort, tightly stick take in the car paint surface, resist oil, rain and snow, such as corrosion, even if the car exposed in the sun for a long time, the car paint is not easy yellowing and aging.

 

Does the invisibility Cloak really work?

 

Don't be afraid to splash stones, the key will not scratch?

 

It depends on whether TPU materials are used or not. For non-TPU automobile paint protective film, obvious scratches will still appear in case of stone splashing. TPU material can play a good protective role, basically not affected. Due to the toughness of TPU material, minor scratches will be repaired automatically. The repair effect mainly depends on the depth of scratches and the use environment. If the scratch is deep, it can be heated by the gun and polished mechanical friction to achieve a quick repair effect. Does it really resist corrosion? The paint is exposed to rain water, bird droppings and gum for a long period of time. These substances have different acidity, and their corrosion on the paint is a long process, which is not easy to be seen by the naked eye. But after a few years in comparison to new cars will find that the paint is no longer bright, began to lose luster, this is the result of corrosion, directly affect the value of used cars. The corrosion resistance is related to the top coating of the coating and determines its corrosion resistance.

 

 

 

Time is long can you hair yellow bubble?

 

It depends on the raw material and the glue process. Generally, high-end automobile paint surface protection film with more than 10,000 yuan can resist yellowing for more than 3 years and resist aging for about 5 years. At present, only two companies in the world have mastered the production technology of yellowing TPU (removing or modifying the yellowing molecular materials). The code names of these two materials are 49510 of American company and PX98 (resin code) of Japanese company. Other companies do not have this technical strength. The reporter learned that at present, some enterprises have tried to produce non-yellowing TPU products, but it is said that its small batch production process will cause some harm to operators, and finally give up the attempt. Therefore, most enterprises will add ultraviolet absorber in TPU to reduce the yellowing speed.
