Why Does Car Paint Bubble

2019-07-09 636

There must be no bubbles in the paint of a new car. Usually, the phenomenon of bubbles in the paint of a car is only present after the car undergoes innovation in repainting from scratch. There are many reasons for side blistering, and the most likely cause is the influence of moisture. What are the specific reasons for this? Next, let's follow the editor to learn more!

The first type is that after the car is painted, water is inside the paint film. When it is hot, it needs to evaporate, which will form pressure on the exterior of the car paint, causing bubbles to bubble. When it is cold, that is to say, the temperature is not that high, and the bubbles disappear. In fact, it is the same principle as heat expansion and cold contraction. Therefore, when we paint the car, we must be dry about the paint film and do not allow any water to be left on the side. This situation is basically due to improper paint operation, such as incomplete drying after water grinding, the use of gasoline instead of oil remover on the substrate, and incorrect paint ratio!

The second type is that the quality of car paint materials is not up to standard. Due to rainy and humid weather, moisture can easily invade the inside of the paint, and when the temperature rises, the paint film on the surface will seal the moisture inside. If the moisture cannot come out after evaporation, it will cause blistering on the surface of the paint. So the quality of car paint must be up to standard. If car paint needs to be painted, it is necessary to choose a large, legitimate car paint factory or 4S store. We always advise all car owners that cheap goods are not good, good goods are not cheap. If you want good quality, don't worry about prices! In this situation, we can only find a car paint factory to polish and innovate from scratch!
