How to spray varnish to brighten?

Varnish for automotive paint is mainly used with the base paint is a transparent varnish, which is inseparable from the base paint in the process, generally spraying the base paint first, and then spraying the varnish, and the varnish provides gloss and protective layer for the base paint.

The base paint is generally a metal flash paint, and the paint film should not be too thick (generally 10-15 μm), otherwise it will affect the flash effect. The thickness of the varnish layer is generally 35-45 μm), which is divided into self-drying type and drying type. The original coating is generally high-temperature baking paint, and the baking temperature is 120 °C-150 °C, and the time is half an hour. Self-drying varnish is generally used in the maintenance industry, it can be dried naturally at room temperature, but also baked at low temperature, and the baking temperature can be set at 50°C-80°C.

The automotive varnish layer has two functions:

one is to increase the brightness and reflectivity of the paint, and the other is to protect the color paint layer.

It has the following four characteristics:

1. The varnish generally contains the protective function of reducing ultraviolet radiation, as long as the varnish layer is intact, it can effectively delay the aging of the pigment coat.
2. At present, the varnish materials used in the original factory are mainly high-temperature cured one-component paints: polyurethane or polyester, and the commonly used varnish materials for repair paints are mainly naturally cured two-component acrylates.
3. The varnish is beautiful and has a high gloss, but it is prone to scratches. If you wipe your car with a slightly stiff towel or suede after washing your car, you will notice scratches on your hair.
4. Varnish is more susceptible to erosion by environmental pollution than ordinary paint. The sources of harmful substances include: carbon black of carbon dioxide released from vehicle exhaust and debris falling from aircraft aviation fuel, such as acid rain, acid mist, acid snow, etc. Once this debris falls on the car, it becomes an acidic solution that corrodes the varnish when it is added to the moisture in the air. As soon as it is heated, a chemical reaction begins to take place, eroding the protective layer of the car paint. Once or twice is not obvious, but if left unattended for a long time, the chemical reaction will eventually erode the color layer, the primer layer and the metal.

How to spray car varnish to brighten？

Automobile paint bright oil is generally sprayed between 2 and 3 times, mainly to see the orange pattern of the varnish for spraying, only need to spray twice after leveling, if you find that there are other parts are not really leveled, you can spray more than once. Automotive paint polish is mainly sprayed 5 to 15 minutes after the base coat is sprayed, and can only be sprayed after confirming that the base paint is really dry. Generally, when spraying bright oil, fog spraying can be used for the first time, and after spraying, it only needs to be uniform, and basically the whole vehicle can be sprayed. The second time to really spray the brightness, the engineer should spray slowly to ensure that every part of the paint can be sprayed, and it is best to spray back and forth.
