Powder coating is a variation on electrostatic spraying. However, unlike certain processes, the particles are solid, not liquid. This offers some advantages over other conventional liquid spraying processes. In fact, powder coatings can prove to be beneficial to those who apply it and those manufacturers who choose it as the method of providing protection for their components.
Basics Advantages of Powder Coatings
Powder coatings are a solid sprayed onto a component to provide it with certain properties. When you use a powder spray, you are able to avoid some of the steps involved in the application of a liquid one. In a conventional liquid spray process, you need to bake following the application of each coat. In the case of powder coatings, a single baking occurs after several layers of spraying, including the primer and the finish.
Moreover, unlike with liquid sprays, finishers can save money. The excess (overspray) resulting from powder coatings can usually be collected for reuse. This reduces the amount of costly waste products, making it more efficient and cost-effective. It is beneficial for both the finishing company and the environment.
Modern powder coating technology is capable of producing high quality finishes. The results are superior surface properties. They accomplish all this at lower costs than other various protective coatings. However, as is the case with all processes, the specific choice of material for the coating process will have an effect on the overall cost of the application. Among basic thermoset powders for powder coatings from the most expensive to the cheapest are the following:
* Acrylic
* Polyurethane
* TGIC polyester
* Epoxy
* Hybrid of Epoxy and Polyester
Beneficial Powder Coating
Powder coatings have certain restrictions. They may not be suitable for such large projects as armored tanks. Yet, they can and do provide several cost-effective solutions for many manufacturing companies. A powder coating is a proven means they can provide the protection necessary for many of their components.
