The Different Types of Powder Coatings
Whether you’re new to powder coatings or an experienced pro, you’re probably well aware that powder coating is a fantastic painting method that creates a tough, durable and beautiful finish. No matter whether you’re using a single gun and small oven or a large fully automated line, the process is basically the same. A powder spray gun is used, which when triggered gives an electrostatic charge to the powder particles passing through it. As the parts to be coated are grounded, the powder is attracted towards the part via the electrostatic process. Once the powder is applied the parts are cured in an oven, which melts and cross-links the powder over the surface of the part and creates a tough, scratch resistant and beautiful finish.

Powder Application Systems
In addition to spray application with electrostatic guns, powder coating materials can be applied by a dip method called fluidized bed. Fluidized-bed powder coating was developed by Edwin Gemmer for application of thermoplastic resins and patented in 1953.
In fluidized-bed coating, parts are preheated to 450–500°F and then dipped into a tank filled with powder material that has been “fluidized” by addition of compressed air through a porous membrane at the bottom of the tank. In some cases, the powder is electrostatically charged.
Another option is flame-spray application. In flame-spray, which is used to apply thermoplastic powder materials, powder is propelled through the flame in a heat gun using compressed air. The heat of the flame melts the powder, eliminating the need for ovens.
Yet another method of application is called hot flocking. In this process, the part to be coated is preheated so that the sprayed powder will gel when it comes in contact with the hot part surface. Hot flocking is often used for functional epoxy applications because it builds a thick film that will provide exceptional performance. These fusion-bond epoxy (FBE) products are often used to coat valves and pipe used in extreme conditions such as oilfield or offshore applications.
