Why Some Car Paints Look High-End

The final effect of car paint is determined by the concept design of Car paint, color matching, paint selection, spraying process, etc. Good Car Paint has reached a high level in these aspects, so it is not only beautiful, but also of good quality. And this kind of high-quality car paint not only looks more upscale visually, but also brings consumers an excellent experience of use.
Concept design of car paint
Different from art design, product design creates infinite possibilities under the constraints of various objective conditions. Some designers once said that their work is like dancing in shackles. Sometimes the product effects they pursue are mutually restrictive, but they must also ensure that the intentions conveyed are consistent with the information received by the recipients. Design posed a great deal of difficulty. For car paint, the conceptual design of a car paint is created by the designer based on the brand language and product definition, and the consistency of information transmission and reception must be ensured in order to be called a successful car paint design.
Color matching of car paint
The color of car paint can greatly affect people's emotions and visual experience, and the human body's perception of color is related to factors such as the brightness, hue, and purity of the color. When these indicators of the color reach a comfortable level, it will be Can bring people a better visual experience. For example, black, white, gray, red, blue and other car bodies are usually more likely to be chosen by consumers because they are not easy to cause fatigue and other complicated reasons. So it seems that high-end car paint must be very meticulous in color matching.
For automobile manufacturers, after the designer creates the car paint conceptually, he needs to communicate with major paint companies on car paint development, and then form various forms of primary design models such as flat panels and curved panels.
After the sample is formed, choose a sunny day to judge whether the color of the sample meets the design intention under sunlight (usually around 10 am or 2 pm). If it meets, start to make engineering model, that is, design standard model. After the engineering model meets various physical property standards and design requirements, it will be issued to each supplier to match the color. The mass production transformation of the production line can only be carried out on the premise of adapting to the production line process and meeting the design requirements.
Therefore, the color matching of car paint is a very meticulous work, and the result of color matching plays a decisive role in the texture of car paint.

Paint use for car paint
The most basic component of car paint is paint, including pigments, metal flakes, mica, glass flakes, etc. The raw materials, mixing ratio and spraying process of the paint are different, resulting in the diversity of the visual experience of the car paint. And precisely because of the different raw materials, the common car paints on the market are also divided into the following three types:

1. Plain paint
Ordinary plain paint is the most commonly used car paint. It is composed of resins, pigments, Additives and other components. Most of the common white, red, yellow and other plain paints on the market are plain paints. Because it is necessary to ensure the purity of the color, the things added are relatively simple, which also leads to a relatively monotonous color, which is far inferior to the texture of pearlescent paint and metallic paint, and the price is relatively low.
2. Metallic paint
Metallic paint is mixed with metal powder, such as aluminum flakes, so when light shines on it, it will have a metallic luster. Compared with plain paint, metallic paint has better sparkle and is more beautiful in the sun; the paint surface is relatively not easy to be scratched, which reduces the cost of touch-up paint and baking paint. The price of metallic paint is between ordinary paint and pearlescent paint, and it is often applied to mid-to-high-end models. In addition, only after the surface is sprayed with varnish, the metallic paint will show luster and hardness, and play an anti-oxidation role. Most dark car paints, such as blue, green, silver, etc., are metallic paints.
3. Pearlescent paint
The mica material is added to the pearlescent paint, and when the light shines on it, complex refraction will occur in the mica particles, and the mica will reflect different hues such as green, brown, yellow and pink, and the titanium dioxide component in the mica has reflections in different directions. The characteristics of different Colors bring the pearlescent paint a colorful visual effect like pearls.
Spraying process of car paint
The coating process of car paint is also a very important part. Before talking about the coating process, let's first understand the structure outside the steel plate. Generally, the mass production process of car paint is divided into two-coating (more in the market) and three-coating (less in the market), which largely determines the final rendering effect of car paint.
At present, the mainstream second-coat car paint is divided into 4 layers, which are electrophoretic layer, middle coat, color paint layer and Clear Coat layer. Among them, the electrophoretic layer and middle coat are the base layers of all car paint spraying.

So, what steps does a car go through to put on a gorgeous coat? First of all, the finished car body without any decoration after passing the inspection is sent to the painting workshop to start painting and complete a pre-treatment process. Then the car body is subjected to electrophoresis treatment, and the car body is immersed in the electrophoretic liquid. The resin and pigment in the electrophoretic liquid will move to the car body under the action of the electric field, so that the car body is covered with a smooth and uniform paint film. This process is very important for strengthening the car body. Corrosion resistance helps a lot. After the electrophoresis completed body is washed and dried, it enters the glue coating and sealing process. The body will be coated with a large amount of PVC glue to improve the sound insulation and corrosion resistance. After the body is glued and sealed, the body begins to be sprayed with an intermediate coating, including steps such as wiping, spraying, and drying. In this process, dust removal is very important, and a very small amount of dust may cause unqualified spraying. Finally, it is polished to make the appearance of the car body paint film brighter and more beautiful. After the middle coat is sprayed, the spraying of the color paint layer starts, and the spraying of the color paint layer is completed by a robot. Next is the spraying of the outermost paint layer - the varnish layer. In the process of spraying varnish, the spray will be sprayed electrostatically, which can make the varnish adhere to the surface of the car body more evenly, so as to improve the quality of the car paint. After the painting is completed, the body spraying has reached the last process-drying. The drying process is very strict in temperature control, usually at 140-150°C, and different factories may have different baking temperatures. The car paint spraying process affects the thickness, hardness and corrosion resistance of the car paint, and the control of these indicators is inseparable from the final effect of the car paint. For example, the thickness of car paint is related to the model and specific parts, generally between 120 and 180 microns, and the Mohs hardness is only 0.4-0.6. The thickness of special parts, such as roof, door panel and front cover, may be slightly different.
