Electrophoretic coating utilizes an external electric field to direct the migration and deposition of pigments, resins, and other particles suspended in the electrophoretic liquid onto the surface.One of the coating methods for the base surface of the Ji product.

The principle of electro-phoresis coating was invented.Electrophoretic painting, a specialized film-forming method developed in the late 1930s but only gaining industrial application after 1963, has emerged as a significant construction technique for water-based coatings over the past three decades.

Water-soluble, non-toxic, and easy to automate control, it has quickly gained widespread application in industries such as automotive, construction materials, hardware, and home appliances.
