The current conventional way of powder coatings has been potentially updated with the promotion of graphene powder coating. Its properties have made the coating process environment-friendly, efficient, and energy-saving. It is widely used in the protective layering of metal surfaces in various industries, for instance, shipping, rail transit, road facilities, household appliances, electrical equipment, automotive parts, and many others. When graphene applications are considered, graphene powder coating has been a great discovery. Moreover, it has been an important move in developing the powder coating industries and for improvement in coating performance. Additionally, its curing diminishes energy consumption. Graphene powder coating has a high density that helps in the improvement of its anti-oxidative and anti-corrosive characteristics, which ultimately extends its service life. Graphene coating is also resistant to corrosion of elements and substances like ultraviolet rays, rain...
