Analysis and comparison of the advantages and disadvantages of electrophoretic paint and self-swim paint

At present, many people are not unfamiliar with electrophoretic paint. However, they may not be familiar with self-swim paint. I believe many people may not have heard of it. So what is a freestyle paint? What is electrophoretic paint? Hong Heshun Xiaobian came to compare and analyze.

Self-swimming paint painting has only appeared in recent years. It is a new process developed on the principle of electrophoretic painting. It can be understood literally that self-swimming paint painting does not require electricity. The chemical principle produces a potential difference that causes the paint to deposit on the surface of the workpiece to form a paint film. The electrophoretic paint must be applied with direct current, and a potential difference is generated under conductive conditions, so that the paint ions with dots can be adsorbed on the surface of the metal to form a paint film.

Theoretically, self-swim coating has great advantages over electrophoretic coating, and the limitations of coating are small. However, as far as the current market application is concerned, there are not many self-swimming coating processes on the market, and basically they are still in the experimental stage. The performance of the products made is unstable, and various disadvantages are emerging. Electrophoretic coating is very common, and the process of electrophoretic paint is quite mature. As for automobile coating, more than 90% have adopted electrophoretic coating process.

Self-swimming coating features: Compared to electrophoretic paint, the self-swimming paint has a small paint density, so the salt spray time and adhesion tests have excellent performance. With water as dispersant, it is a safe and environmentally friendly coating. No electricity is needed during painting, just put the workpiece in the tank. Painting equipment is simple.

Disadvantages of self-swim paint: single color, currently only black and gray. It is only for steel parts and does not react with other metals.

Next, we will talk about the characteristics of electrophoretic coating: electrophoretic coating can be automated production and high production efficiency. Compared with the previous dipping process efficiency can be improved by more than 45%. Electrophoretic coating is uniform and dense. Even the edges and corners can be coated with electrophoresis, and the corrosion resistance is much higher than self-swim paint. Electrophoretic paint film has good water resistance and strong paint film adhesion. The concentration of the electrophoresis bath is very low and the viscosity is small, so the loss brought by the workpiece is also small, so the utilization rate of the electrophoresis paint can reach more than 95%, and even higher.

At the same time, because the electrophoretic paint can do various color effects on the metal surface, the application range is very wide. In summary, electrophoretic paint coating is a relatively advantageous method in the current metal surface treatment, so the application of electrophoretic paint is relatively wide, and it is applied to automobiles, home appliances, and electronic products.
