Can the workpiece after electrophoretic paint be conductive?
With the continuous development of the industrial level, there are more and more choices for metal surface treatment. After the electrophoretic coating technology is more and more mature, a large part of the metal surface treatment market is occupied by electrophoretic coating. However, in some special fields, when metal surface treatment is required, some special functions are also needed. For example, after the treatment is completed, the metal surface also needs to have conductive properties. Then, is there still conductive properties after electrophoretic coating?
The following electrophoretic paint manufacturer Hongheshun Company will announce the answer for everyone.
Electrophoretic paint is divided into cathodic electrophoretic paint and anodic electrophoretic paint. All belong to water-based coatings. The reason why water-based resins can be diluted and dispersed with water is mainly because the polymer molecular chain contains a certain number of hydrophilic groups, so the resin itself does not have conductive properties. However, the electrophoretic paint is conductive. Because of the presence of polar ions, cations can conduct electricity when they swim. Therefore, the electrophoretic paint film can conduct electricity before drying and curing, and can not conduct electricity after drying and curing after electrophoresis.
In summary, the finished product after the electrophoretic coating of metal products is equivalent to forming an insulating film, so the surface cannot be conductive.
If you choose a metal surface treatment, and you also need the surface to be conductive, the most suitable is to choose electroplating coating. Therefore, when you choose the surface treatment, you must choose the appropriate coating method according to the needs of your own products.
