All You Need to Know About Powder Coating

Powder coating is the process of deposition of the polymer resin on the surface of the substrate. The polymer resin is sprayed electrostatically on the electrically ground metal substrate ( www.sun-glo.com/powder-coating-services ). It is a dry process of metal coating. It can be used for the decorative and protective coating of the metal parts used in the industry as well as in domestic use. Hence, when it comes to the coating of metal parts, powder coating is the best in business.

How does Powder Coating work?

Powder coating on the metal workpiece is achieved by the electrostatic deposition of powder on the electrically grounded surface of the metal. First of all polymer resin is powdered and mixed with pigments, and then this mixture is sprayed using an electric gun. This process is called electrostatic spray deposition.

After spraying the powder, the metal surface is heated in the oven to cure. This allows the polymer resin to produce long molecular chains which are highly durable. Heating allows powder to fuse firmly on the surface of the substrate. Hence this process results into the uniform layer of powder coating on the surface of the substrate.

Advantages of Powder Coating

Powder coating services have been used in the metal finishing industry for many years. It offers numerous advantages. Let’s have a look at the key advantages of powder coating.

Last Long

Powder coating is highly durable. It does not crack or chip away easily and highly corrosion resistant. High resistance against moisture and abrasion makes it last longer. The thickness of powder coating is four to ten times more than the wet paint. This makes it tougher and better protects the substrate. Whether you are using it for the finishing of industrial metal parts or domestic metal products, it can provide uniform and highly-durable finish.

Decorative Finishing

Powder coating is not only about protective finishing, but it also provides great decorative finishing to a metal surface. It gives the metal substrate a vibrant finishing that looks really beautiful. Also, it is available in a multitude of colors. You can choose any color of finishing you want. Also, colors of powder-coated surface do not fade away easily.

Environment-friendly and Safe

This is a major reason behind encouraging the use of powder coating services. Powder coating does not protect metal parts ( https://www.sun-glo.com/blog/ ) at the cost of environment. It does not use solvents or release volatile organic compounds which cause harm to manufacturer and environment. It is an environment-friendly process. Also, unlike wet paint, powder coating is inflammable and provides extra safety to consumers.

Final Thoughts

Powder coating is tough, durable and looks great. If you are looking for the high-quality finishing for you metal parts, powder coating is one of the best metal finishing methods you have. More importantly, hiring a powder coating services can easily fit in your already strained budget.
