Powder coating is a unique and straightforward process of finishing that serves as an alternative to conventional wet paint. It’s used on many of our everyday appliances and vehicles, and results in a beautifully finished product.
Here is a brief overview of how that process looks.
Blasting
To prep the surface to be powder coated, the metal is first sandblasted. Sandblasting removes any rust, dirt, debris, and/or corrosion from the surface, as well as any existing paint or powder-coated finishes. Any metal can be sandblasted— such as iron, alloys, steel, and aluminum.
Prepping
Once the surface has been sandblasted—and all debris, corrosion, rust, and/or paint has been removed from the surface— it is then prepped. Prepping involves applying a specialized metal prep chemical solution, which neutralizes the impurities on the surface and cleans off any remaining debris, while also preventing rust and corrosion. There are many types of solutions that can be used to improve the surface of the metal before it’s coated, depending on the specific type of metal.
Powdering
Once the surface has been fully prepped and is completely dried, it can be powder coated. An electrolysis process is used to apply the powder coating, which allows the metal to positively charged so that the powder can be attracted to and bond with the metal.
Then voila! The process of powder coating is done.
