Car paints are generally baking paints. In the depot, after the frame and shell are welded (and sometimes repaired by hand), the next process is painting. Generally, the primer comes first. Dip the bare car shell into the syrup-like paint tank, take out the drying primer; then send it to the dust-free workshop, and spray the topcoat with the electrostatic spray painting process. Then dry it at a temperature of about 200 degrees. To be precise, there will be another coat of varnish. In this way, the paint process is done.
There are several kinds of general finishes: 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 when finished. Pearl paint, the addition of mica particles. Mica is a thin piece of things, so the reflection is directional, and there is a colorful effect. If it's metallic paint plus a clear coat, the car's paint looks 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; and the amount of titanium dioxide in the 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.
No matter what color of paint, its pigment will fade in sunlight. In fact, not only paint, but anything with color can fade in the sun. At this time, the additives added to the paint are very important. Such as light stabilizers, such as antioxidants or something. Unfortunately, good additives are expensive and expensive. Many times, the quality of the additives determines how the paint feels. One would definitely think that a paint that starts to fade noticeably after 2 years is inferior to a paint that is shiny like new after 5 years. But in reality, there is no paint that does not fade. SHINESELL tells you that many times, the manufacturer is more concerned about: uniform fading. Try not to make chromatic aberrations appear in different parts of the car.
SHINESELL reminds that when a new car arrives, the most easily damaged is the paint. If you wash your car carelessly, the paint will hurt. In fact, even when loading things on the production line, there are things that damage the paint.
Generally small scratches, there are scars on the paint surface, and the scars are white. That is the paint surface is scratched. There is no need for touch up paint. Lightly, sand or wax a few times. Heavy, just do a polishing.
Seriously, you can see the color of the underlying primer (many times, the primer is a dark color). Then, look again at the site of the scar. Generally speaking, bumpers, rear-view mirrors and wheel arches of some cars are made of engineering plastics. stainless. Apart from being ugly, there is no big problem. It doesn't matter if it's repainted or not. Otherwise, even if it is a small damage, the steel plate will start to rust. At that time, it will be difficult to prevent embroidery even if the paint is repaired.
