Powder Is Applied to Item During Powder Coating Process

Why Powder Coat? Benefits of Powder Coating Components

There are many ways that components and products made at Custom Laser can be finished to make them ready for our customers, but one of the most common and durable options is powder coating. Available since the ‘60s, powder coating has been highly praised for its benefits for metal items for more than half a century, but has become even more popular in recent years for its eco-friendly benefits.

What Is Powder Coating?

Powder coating is what’s known as a dry finishing process that delivers a colorful, durable and consistent finishing coat. Typically, this is done with metal products or components, but can also be applied to other materials like fiberboard and plastic. The Powder Coating Institute notes that powder coating now represents more than 15 percent of the total industrial finishing market today across all markets and applications.

The powder itself is a polymer resin base with additives used to give the powder its color, change the flow rate or curing time and control other factors of the coating process. Using an electrostatic spray deposition process, the powder is applied to the surface of the part or component, creating a charged attraction between the coating and the grounded part. After application, the piece goes through a curing oven which causes a chemical reaction that creates long molecular chains which link the coating with the surface, resulting in the finished item.

Why Choose Powder Coating?

Beyond the ability to create a finished look in a full spectrum of color choices, powder coating is incredibly popular for its durability. A powder coated item has much greater resistance to scratching, chipping and fading, meaning that finished pieces will stay looking sharp and protected for longer than painted items. In addition, powder coating offers greater resistance to the elements, protecting the surface from moisture, UV rays or other environmental factors. This is also why you frequently see powder coating on heavy machinery, grills, outdoor furniture and other components and parts that are exposed to weather conditions and tough work environments.

You may also be surprised to learn that powder coating is also incredibly ecofriendly – more so, even, than paints. Because powder coating is completed in a closed and sealed space, it eliminates the risk or spills or contamination. Powder coating is also recyclable, with unused powder able to be reclaimed for future use. The process from start to finish also produces nearly no volatile organic compounds (VOCs), making it much easier to be compliant with environmental regulations and standards.

Finally, with a far greater life expectancy for powder coating versus paint coating that may need to be reapplied, the finishing process offers a smaller carbon footprint. This not only helps reduce overall impacts to the environment by eliminating the need to repaint, but also prolongs the life of the finished part, component or product, helping diminish the need for replacement.

When Powder Coating Won’t Work

While powder coating offers many advantages for finished components, there are a few instances when it isn’t the best choice for customers. For example, powder coating is nearly impossible to apply thinly, so if your component has very stringent thickness requirements or tight part clearances, you may need to choose an alternate finish option. In addition, powder coating can be difficult to color match precisely from one batch to another due to the nature of the powdered coating. If you need to color match exactly, you may be better using a paint or other coloring process.
