The outstanding advantages of powder coating technology

Powder coating technology, also known as powder coating, is a new type of coating technology that has rapidly developed in recent decades, using plastic powder as the raw material. As early as the 1940s, some countries began researching experiments, but progress was slow. In 1954, James from Germany successfully coated polyethylene using fluidized bed method. In 1962, after the invention of powder electrostatic spraying by Semis from France, powder coating began to be officially adopted in production. In recent years, due to the emphasis on environmental protection in various countries, powder coatings that do not pollute water and air have developed rapidly. The following are the outstanding advantages of powder coating technology. Guangzhou WLD equipment co.ltd is a professional suppliers and manufacturer of powder coating booths and lines in Guangzhou,China.

1. A single coating can obtain a thicker coating, for example, coating with a thickness of 100-300 μ m. Using ordinary solvent coatings requires about 4-6 coats, while using powder coatings can achieve this thickness in one coat. The corrosion resistance of the coating is very good.

2. Powder coating does not contain solvents, has no three waste pollution, and improves labor hygiene conditions.

3. Adopting new processes such as powder electrostatic spraying, with high efficiency, suitable for automatic assembly line painting; The powder has a high utilization rate and can be recycled.

4. In addition to thermosetting epoxy, polyester, and acrylic, there are also a large number of thermoplastic grease resistant materials that can be used as powder coatings, such as polyethylene, polypropylene, polystyrene, fluorinated polyether, nylon, polycarbonate, and various fluorine-containing resins.

Powder coatings have begun to be used for protection and electrical applications. With the development of technology, they are now widely used for surface coating in the automotive industry, electrical insulation, corrosion-resistant chemical pumps, valves, cylinders, pipelines, outdoor steel components, steel furniture, castings, and other areas.
