The most comprehensive explanation of automobile color-changing film and selection skills.

In order to meet our growing demand for personalization, fashion and modification, automobile color-changing film can be said to be the standard configuration for modified car users at present. So today, we will spend a little time talking about automobile color-changing film, which I believe will be very helpful for riders to choose color-changing film in the future.

First of all, the issue of policies and regulations has been emphasized in an article in previous issues, and riders who want to know can read the previous article. According to the latest regulations on car color change, there are no more than three car body colors. Except for the colors used by special vehicles such as fire engines and engineering vehicles, car color change is legal without affecting road safety, but you need to go to the vehicle management office to change the car color within 15 days after the color change is completed.

Second, the demand for color change. I think this problem needs to be divided into at least two levels. First of all, why change the color? Naturally, it is necessary to meet the individual needs of our riders, show their personalities and share more advantages and disadvantages, which is what we will focus on later. Secondly, what color should I change? This question is actually the most difficult question to answer. Whenever we see some favorite colors on the road, we will wonder if it looks good if it is pasted on our car body. Therefore, the question of choosing which color is really a matter of opinion.

Third, the advantages and disadvantages of color-changing film.

1. Advantages:

(1) Sticking the whole car is basically harmless to the car without damaging the paint surface of the original car. At present, the product technology and quality can reach the situation of infinitely approaching zero harm, covering the whole car surface without splicing and seams, and perfectly showing the streamline of the car body, including the front and rear bumper corners with large radians.

(2) Compared with vehicle painting, film pasting construction is relatively simple, which adds another layer of film protection for vehicles.

(3) Extremely high durability. At present, the service life of new products on the market can reach 5 years or longer, and the color remains beautiful without fading.

(4) isolate corrosion and protect the original car paint. Because there is a protective film on the surface of the car body, it has a strong protective effect on corrosive car paint such as asphalt, rain and snow.

2. Disadvantages:

(1) Damage of back glue to car paint. The material of the film itself is generally excellent, and most of them are environmentally friendly, safe and harmless, but the film will still be attached to the car body after all, so the adhesive backing is a very headache. At present, some big brands of color-changing films use no residual glue, which is relatively safe. Generally, after several years of wind, rain and sunshine, the film on the surface of the car body is removed. After the film is removed by heating, the adhesive residue can be reduced to below 30%. After using some micro-chemical adhesive remover, the surface of car paint is basically not damaged.

(2) paint damage caused by improper construction. At present, there are many shops with low threshold and high profit in the market, so many construction shops without formal training and actual construction experience may damage the original car paint. Therefore, it is necessary to choose a reliable construction shop when choosing.

(3) Disassembly and assembly of external parts of the car body will cause damage to the vehicle and generate abnormal noise. Due to the film pasting construction, some peripheral parts of the car, such as door handles, left and right rearview mirrors, need to be removed before the film pasting construction, and individual models may need to remove the front and rear bumpers (less). Therefore, after these disassembly, the fragile clip mechanism may be damaged during reinstallation, and there may be instability and even abnormal noise during driving in the future.

Fourth, the popularization of color-changing film raw materials. The standard color-changing adhesive film consists of four layers, namely, mask, adhesive, silicon coating and backing paper.

1. Back adhesive, also known as pressure-sensitive adhesive, is an adhesive that exerts a certain pressure on it, thus producing adhesive force on the pasted substrate. This is an adhesive that can keep sticky for a long time. By changing the formula in the adhesive, we can produce common permanent and removable adhesives with special uses. Therefore, this is the quality of the above glue.

Mask is the main part that we can bring us the most intuitive feeling. Types of color-changing films: PVC film is the most commonly used, casting grade PVC film is the most expensive, followed by chain calendering grade and monomer calendering grade.

(1)PVC film is the most widely used material in the market at present. The manufacturing method and technology of this film determine the quality of the film. PVC plasticizer and other additives added in the process of manufacturing PVC films are the secret weapons of various brands of films.

(2)PVC is divided into two different types: monomer, the most basic plasticizer type, which is very unstable. At present, some cheap films on the market are monomer films, which have very short service life and obvious fading. 2. The chain has a more complicated structure and better flexibility and durability. Chain film is a better brand among domestic films at present, and its frequency of use is relatively high, and imported films are also used more. Therefore, when choosing a color-changing film, riders should focus on asking the store whether the film is a monomer film or a chain film, and they can make their own judgment.

(3) Components of casting grade PVC film, PVC raw material, automotive grade lead-free pigment, chain plasticizer, high temperature stabilizer, advanced ultraviolet blocker, chemical organic solvent and casting film paper. This film will be made of casting paper and coated with some mixed chemical sol. After a series of complicated technological processes, the film will be finally made. This film has excellent dimensional stability, outdoor durability and flexibility, rich and varied colors and basically does not fade. However, due to the high requirements and complexity of the process, the cost is much more expensive than the ordinary process, so some high-end brands in the market adopt this casting-grade PVC process.

Therefore, in view of the materials of several mainstream color-changing films on the market, riders should remember to ask more about the process of brand color-changing films used in stores when choosing stores to communicate, so that you will know roughly what grades and levels you should pay in exchange for a set of body color-changing films.

Fifth, the choice of color-changing film. Through the introduction of some basic knowledge above, I believe that most riders should have a certain understanding of this color-changing film. It is a good thing to change the color of the car body, but the color-changing film is covered on the car paint after all. If you use inferior color-changing film, it may seriously damage the car paint, so it is very important to choose a good color-changing film. So what should we choose when we choose a movie?

1. Price, as the saying goes, is worth it. Understand the price of all grades of color-changing film market, and then make the right choice according to the material of the film.

2. Observation, we should fully observe the color of the film before deciding on the choice. A good color-changing film is full and balanced, and a bad film surface will be particularly grainy.

3. Touch, the color-changing film with good quality has fine surface, appropriate thickness and is not easy to wrinkle. Then a rotten film is just the opposite, with a rough surface and lack of toughness.

4. Adhesive backing. After some simple tests, the quality of adhesive backing is easy to show. After several pasting, the stickiness of the adhesive back is still very good, which should be a good adhesive back. If the viscosity of the adhesive backing is only tested once or twice, it will not work, so it must be defective.

5. Big brands, basically needless to say. As long as it is genuine, there should not be much difference in the technology, workmanship and even construction level of the store, which depends on whether there is enough money in the pocket.

Finally, some basic knowledge about color-changing films and the methods of selecting and distinguishing color-changing films are so much. I want to remind you that the color-changing film introduced today is a kind of film that is purely used for color change. It doesn't have the repairing effect of invisible car clothes. For some collisions, the color-changing film basically has no substantial effect on the protection of car paint. In the near future, we will find a special opportunity to introduce this invisible car clothing to drivers.

If you don't know about the use and selection or need advice, please leave me a message at any time and I will reply one by one.
