Why is the paint on the surface of the water cup easy to peel off after spraying?

Many times, after you buy a water cup, you will find that the surface of the water cup is peeling off after not long after use. Some are accidentally bumped by themselves, and some are the paint on the water cup itself, so what is the reason for the paint on the surface of the water cup?

Spraying is a coating process in which spray guns or atomizers apply pressure or centrifugal force to the surface of the object to be coated. The spraying process has high production efficiency and is a very common coating method today. However, the environment, equipment and technology required for the spraying operation have their own strict and tight processes. A fault in one of the links will easily cause the production to fail and cause the paint on the surface of the water cup to easily fall off.

First of all, the environment required for the spraying operation requires dust-free spraying, and the surface must be clean, otherwise the adhesion of the surface paint will be greatly reduced. Secondly, the paint requires regular paint, and there should be no problems of insufficient quality. When spraying, pay attention to the actual spraying effect and adjust the baking temperature according to the characteristics of the paint. Too high or too low temperature will cause the paint to be unstable.
