1. Why did the paint explode?
The so-called paint explosion means that the paint you originally painted has been exposed to the sun, or after the plum rain season, the temperature changes, resulting in the cracking of the paint on the door or furniture. This situation of stainless steel signs should be due to the insufficient adsorption of stainless steel on paint, and the paint can not be well adsorbed on stainless steel.
2. How?
The solution is: activate the surface of stainless steel signs. The common treatment is electrolysis or passivation. If the surface finish is not considered, vibration polishing can also be used. The principle is to make the surface of stainless steel sign not so smooth. Under the micro level, the surface is composed of small concave points, which can greatly improve the adsorption of paint on the surface of stainless steel sign.
