Because powder coating does not use solvent, it has been recognized to be safe causing no pollution, resource saving by paint recycle , and easy for handling and automation providing high workability, which leads to the expansion of the use of powder coating. As the environmental problems are recognized as global ones, efforts to conserve the global environment are increasingly strengthened on a worldwide scale, and now the environmental problems are those that companies cannot avoid. As seen in the VOC regulations of the painting industry, as a method of reducing organic solvents discharged into the atmosphere, the transition to powder coating, water-based and high-solid paints are searched for. Among them, powder coatings can be recovered and recycled without solvent, so they are promising paints for environmental response. The production volume of powder coatings has declined considerably just after the Lehman shock in 2008, but since then it is steadily increasing coping with the environmental problems. This review discusses the market share and future prospects in powder coating industry with its basic technologies and problems, and the latest technologies, including features and advantages of Wagner products.
