Anodized electrophoretic acrylic resin was commercialized in Japan in the 1960s and began to be used in Europe until the 1970s. Currently, it is mainly used in Asia. This technology has currently evolved from transparent and bright films to non transparent and color films, with a more diverse variety of varieties. Industrial control and product quality are relatively stable
Electrostatic spraying after chemical conversion treatment includes electrostatic powder spraying and electrostatic liquid phase spraying. Electrostatic liquid phase spraying fluorocarbon resin was commercialized in the United States in the 1960s. Electrostatic powder spraying thermosetting polyester coatings, which were commercialized in Europe by the late 1960s, are still the dominant surface treatment method in European countries. To this day, the single anodized aluminum doors and windows have significantly shrunk in both domestic and international markets. Japan prefers electrophoretic coatings, while white electrophoretic coatings have developed rapidly and have been applied in Europe. Electrostatic powder spraying has become the preferred surface treatment method in Europe and America due to its diverse colors, convenient control, environmental protection, and excellent performance. In recent years, the market for electrostatic powder spraying has also been rapidly expanding in China.
Spray painting: Usually fluorocarbon spraying is used, and the treatment before painting the aluminum plate is quite important. Passivation treatment is required to ensure a tight connection between the paint and the aluminum plate. A typical use is to use this method for surface treatment of curtain wall aluminum plates.
