The difference between car painting in summer and winter

The difference between car painting in summer and winter. Today’s society cannot do without cars, so many families will buy cars. As our experience in car care continues to As we learn more and more about cars, the following is the difference between car painting in summer and winter. Differences between car spray painting in summer and winter 1

Generally speaking, there is not much difference between winter painting and summer painting. However, due to the low temperature in winter, solvents and thinners are not easy to volatilize, resulting in slow drying of spray paint and easy sagging when spraying. When the temperature is high in summer, the thinner evaporates faster and the spray paint dries faster, but the thinner cannot dry too fast. If it dries too quickly and at too high a temperature, the paint film will lose its luster. Automotive paint manufacturers provide different types of curing agents and thinners according to different seasons.

Fast drying is generally used for low ambient temperatures (below 15℃ in winter), while slow drying is generally used for high temperatures (above 30℃ in summer). Automotive touch-up paint and ultra-fast-drying varnish are must-have products in winter and can greatly save application time.

Car touch-up paint is usually not affected by the season. The specific needs are determined according to the damage of the car. Spring is usually better, and the construction is best at a temperature of 25°C and a humidity of 50% (avoid Construction in rainy and foggy weather).

Paint repair is usually done in the car factory. After the frame and body are welded and the body is repaired manually, the next process is painting. Generally, the first step is the primer. The white leather car body is immersed in a syrup-like paint tank, and the primer is taken out and dried; then it is sent to a dust-free workshop, where the topcoat is sprayed using an electrostatic spraying process, and then dried at a temperature of about 200 degrees.

Extended information:

When repairing paint, you need to carefully check the damaged part. If the damage exceeds one-third of the part, excessive repair should be carried out. repair. Over-repair means spraying the entire part with varnish, and the color paint is transferred from the damaged area to the original paint, maximizing the retention of the original car paint.

At the same time, it also avoids the problem of color difference. Because one-third of the damage after polishing, primer, paint, varnish and joints exceeds two-thirds of the part, the remaining part is very small, and the meaning of repair is lost.

The temperature is low in winter and the diluent is not easy to volatilize, which causes the paint film to dry slowly and sag easily during painting. However, there are baking rooms for painting. Generally speaking, painting in winter is different from painting in summer. It doesn’t matter. You can’t spray paint without baking it on a cold day, so you have to wait until it dries.

The temperature is high in summer, the solvent evaporates faster, and the paint film dries faster, but the thinner should not be too high. It dries quickly. If it dries too quickly and the temperature is high, the paint film will develop heat rash and lose its luster.

Automotive paint manufacturers will prepare different types of curing agents and thinners for use according to different seasons. If the ambient temperature is low, (less than 15℃ in winter) generally use quick drying, and when the temperature is high (higher than 30℃ in summer) generally use slow drying. The standard temperature range is 15°C to 30°C.

Note: For partial car repair paint in winter, ultra-fast drying varnish is a must-have product, which will greatly save construction time.

In fact, car paint can be touched up all year round. Regarding whether it is better to touch up car paint in summer or winter, the time for car paint touch-up depends on the type of car paint process. There are two car paint processes, namely spray painting process and baking paint process. If you use the spray painting process, the paint solidification and drying time of the winter spray painting process is relatively long, at least twice as long as spray painting in the summer. As for the baking process, there is little difference throughout the year, and the temperature has no effect on the solidification and drying of the paint in the baking process.

From the effect point of view, whether using spray painting process or baking paint process, the effect is the same all year round, there is no difference. Regarding the difference in effects between the two processes for car paint repair, the effect of baking paint is generally better than that of spray painting, and the process is complicated. Each process must be completed in a dust-free paint room.

Generally speaking, there is not much difference between winter spray painting and summer spray painting. However, the temperature in winter is low and the solvent thinner is not easy to volatilize, causing the spray paint to dry slowly and the paint to sag easily when spraying.

The higher the temperature in summer, the thinner evaporates faster and the spray paint dries faster, but the thinner cannot dry too fast. If it dries too quickly and the temperature is too high, the paint film will lose its light. Automotive paint manufacturers will provide different types of curing agents and thinners for use according to different seasons. Fast drying is generally used for low ambient temperatures (lower than 15°C in winter), while slow drying is generally used for high temperatures (higher than 30°C in summer). Automotive touch-up paint and ultra-fast-drying clearcoat are must-have products in winter and can significantly save application time. Differences between car painting in summer and winter 3

It can be done. At present, touch-up paint is divided into two types: spray painting process and baking paint process. The spray painting process can also be applied in winter, but the solidification and drying speed of the paint is very slow. It usually takes twice as long as in summer, and it will not have much impact on other aspects.

If you use the baking paint process, there will be no impact all year round. Because the painting process needs to be completed in the paint room, the drying conditions in the paint room are very stable, and the drying speed of the paint will not be affected even in winter. In terms of effect, there is no quality difference between winter touch-up and summer touch-up under the same conditions.

Because 4S shops or auto repair shops need to schedule repairs, it does not mean that the master can start work immediately if you drive your car there. Even a small 4S shop will take about two days to complete at the fastest. Not to mention the whole car was painted.

At the same time, the dryness of the car's paint will also affect the repair time. If you use spray painting in winter, it will definitely not be completely dry within two hours. Going on the road will only make the repaired area covered with dust. The surface will appear uneven. Therefore, it is recommended that we reserve about two days for repainting.

If you have a professional paint room, it doesn’t matter if you spray paint in winter. It is recommended that friends go to a professional repair agency when repairing car paint. Professional restoration agencies have more complete equipment, and the restoration results are also better.

It is normal for the car paint to be damaged during normal use, and scratches are inevitable.

The vehicle paint is composed of four layers. From the inside to the outside, they are the electrophoresis layer, the mid-coat layer, the color paint layer, and the varnish layer.

After the entire car body is assembled, the robot will soak the car body into the electric pool, so that an electrophoretic layer will be formed on the surface of the car body. The function of the electrophoretic layer is to prevent rust.

After the electrophoretic layer is formed on the surface of the car body, the robot will spray the middle coating. The key function of the mid-coat is also to prevent rust, and it can also improve the ability to bond with the next layer of paint.

After spraying the middle coat, the robot will spray the color paint layer. The key to the color paint layer is to play a beautiful role. The various car body colors we usually see are represented by the color paint layer.

The outermost layer of paint is the varnish layer. The main function of the varnish layer is to protect the color paint layer and improve the gloss of the car body surface.

The varnish layer is a layer of transparent paint.

Most of the minor scratches usually remain on the varnish layer, and the scratches on the varnish layer can be removed by simple polishing.

However, it is not recommended for friends to polish frequently, as this will reduce the thickness of the varnish layer.
