Dr. Cha talks about cars: metallic paint, pearlescent.

Many friends who are new to cars don't know much about the paint on the outside of cars. Today, I will briefly tell you what is metallic paint, what is pearlescent paint and what the car clothes are for.

What is metallic paint?

Metallic paint, also known as metallic flash paint, is a popular automobile topcoat. Fine aluminum particles are added to its paint base. After the light hits the aluminum particles, it is reflected by the aluminum particles and passes through the gas film. Therefore, it looks as if the metal is shining. This kind of metallic flash paint gives people a pleasant, light and novel feeling, so it is very common. By changing the shape and size of aluminum particles, the flash of metal flash paint film can be controlled. Outside the metallic paint, there is a layer of varnish to protect it.

In addition to high hardness, metallic paint can also show the beauty of car body hierarchy. Another reason why "metallic paint" is becoming more and more popular is that it is mixed with metal powder. With the metal composition, the hardness of the paint surface increases, and the paint surface becomes hard, so it is not easy to be scratched. Some "plain paints" are not metallic paints, and the most typical colors are white, black, big red and yellow; It doesn't mean that you can't add silver powder to these colors, but after adding silver powder, the color will not be the original positive color, white will become pearl white, black will become shiny "carbon black", red will become so-called "wine red" and yellow will become "golden yellow".

What is pearlescent paint?

Pearlescent paint, also called mica paint, is also a very popular car topcoat. Its principle is basically the same as that of metallic paint. It uses mica instead of aluminum particles. Mica pigment coated with titanium dioxide and iron oxide is added to its paint base. When light strikes mica particles, it first appears the colors of titanium dioxide and iron oxide, and then complicated refraction and interference occur in mica particles. Meanwhile, mica itself has a special transparent color. In this way, the reflected light has a pearl-like flash. Moreover, titanium dioxide itself is yellow, and it will turn light blue when squinting. From different angles, it has different colors. Therefore, pearlescent paint gives people a novel, colorful and dazzling feeling, which is especially suitable for car bodies with many curved surfaces.

What is an invisible car coat?

To put it bluntly, the invisible car coat is actually a kind of car film, which is different from other color-changing glass films. This kind of glass film is transparent and generally invisible, also called invisible car clothes. Invisible car clothing is a thermosetting polyurethane plastic film. Car paint is widely used in the field of car film beauty care. After installation, the surface of car paint is isolated from gas, which can prevent the harm of acid rain, oxidation and scratches. Many friends put invisible car clothes on the car.

The primary function of invisible car clothing is to protect car paint in many directions. Every day, the vehicle is exposed to wind, sun and rain, and the paint is inevitably corroded and the air is oxidized. It is inevitable that the car body is scratched by falling rocks, gravel and landscaping branches in daily life. Insect carcasses, gum, shellac, etc. It has caused certain damage to the car paint. Attached with invisible car clothes, the car paint is isolated from the external natural environment, which prevents many problems. The strong flexibility of invisible car clothes can protect the car body from physical damage, and also resist ultraviolet rays to avoid air oxidation and yellowing of car paint. Not many people want to stick the invisible car clothes because of the high price, but frankly speaking, the invisible car clothes have its advantages, the actual protection effect is remarkable, and it lasts for a long time, generally it can be stuck for 5- 10 years.
