Over the years, the powder coating industry has evolved in many ways. There are a whole host of examples. Most notably the processing/application equipment used today is much more effective and efficient versus earlier years. In addition, the breadth of substrates being utilized around the globe has evolved to include many nonferrous surfaces along with a series of advances and innovations in the design and development of new raw materials. This holistic approach by a broad array of stakeholders has fostered continuous improvement in the industry.
From an additives perspective, most of the conventional products used in the powder coating industry today are incorporated into the middle of the premix, thoroughly homogenized, transferred into an extruder, pulverized and converted into a micronized powder with a distinct particle size distribution.
