Features of automotive paint products.
All commercial cars in the world are made of steel. Paint is indispensable for embroidering prevention and beauty.
Car paint is generally baked paint. In the car factory, after the frame and shell are welded (sometimes manually repaired), the next process is painting. Generally speaking, the first is the primer. Dip the bare car shell into a syrup-like paint tank, take out the drying primer; then send it to a dust-free workshop, and spray the top paint with electrostatic spraying technology. Then use a temperature of about 200 degrees to dry. For the more elegant ones, another coat of varnish will be applied. In this way, the paint process is complete. There are several general topcoats: ordinary paint; metallic paint; pearl paint. Needless to say, ordinary paints, resins, pigments and additives. The metallic paint has more aluminum powder; so it looks bright after finishing. For pearl paint, mica particles are added. Mica is a very thin piece of material, therefore, the reflection is directional and has a colorful effect. If it is metallic paint plus a varnish layer, the paint on the car looks very bright and beautiful. In terms of color, white is undoubtedly the cheapest. For example, the world-class brand red pigment is about 25 times more expensive than the world-class brand titanium dioxide; while the amount of titanium dioxide used in white paint is about 5 times that of the red pigment. Therefore, the cost of red paint for color is 5 times higher than that of white paint.
Regardless of the color of the paint, its pigment may fade in the sun. At this time, the additives added in the paint are very important. For example, light stabilizers, antioxidants, etc. But good additives are very expensive. In many cases, the quality of the additives determines how the paint feels. People would definitely think that a paint that started to show obvious fading in 2 years is as bright as new paint in 5 years. But in fact, there is no permanent paint. In many cases, the factory is more concerned about: uniform fading, try not to make different parts of the car appear chromatic aberration. "
