Powder coatings were introduced in the late 1940s and early 1950s, at a time when organic polymers in powder form were being flame-sprayed onto metal substrates. So it can be said that powder coatings are the youngest of the surface finishing techniques in common use today. Since the early 1980s, there has been a continual growth for the powder coating industry, driven by constant innovation, improved formulation know-how and advances in application technology and the development of new non-metal applications such as in engineered boards (e.g., medium density fiberboard-MDF), plastics and composites, glass; and lastly given the more ...
