If you’re looking for a coating that delivers on durability as well as quality, chances are you’ve heard that powder coating might be the product for you. If you’re unfamiliar with the process, you may be asking “what are powder coatings?” Today, we’ll be discussing what are powder coatings, what it can offer your project, and how it differs from traditional paint.
What are Powder Coatings?
Introduced in the 1960s, powder coating is a dry finishing process that is used on a variety of industrial equipment. Despite being comprised of powder, as the name suggests, powder coatings are considered to be 100% solids. Unlike their liquid counterparts, they do not require the use of solvents in their formulation. These finishes are available in a wide variety of textures and colors to suit any industrial need.
How does Powder Coating Work?
Powder coats are based on polymer resin systems and combined with curatives, pigments, leveling agents, and other additives. These ingredients are mixed together, cooled, and ground into a uniform powder, similar to cornstarch or flour. Then, once the powder has been created, specialists use a process known as electrostatic spray deposition (ESD), in which the powder is applied using a spray gun. The spray gun uses an electrostatic charge, which is then attracted to the grounded part to which it is applied. Then, once the powder is applied, the product goes into a curing oven. Once heat is added, they create a high-link chain density, which is very resistant to being broken down (which accounts for powder coatings’ durability).
The other method of powder coating, known as liquid powder coating, sees preheated parts dipped into a container of fluidizing powder. The heat from the part causes the powder to melt, which completes the coating. Depending on which process your professional powder coating services uses, a post-dip cure might also be necessary.
What Kinds of Products Can Be Powder Coated?
Specialists can achieve a professional finish on a variety of products, from metal, to plastic, to medium density fiberboard.
What are the Benefits of Powder Coating?
Durability is one of powder coating’s best features, protecting everything from heavy industrial machinery to household products used every day. Its durability allows it to stand up to nicks, scuffs, abrasions, and any other signs of wear and tear you can throw at it.
In addition to being a durable finish for your equipment, powder coating is also cost effective, environmentally friendly, and easy to use. The lack of VOCs and solvents make it a strong choice, as they are less harmful for operators over time.
Powder Coating Vs. Paint?
In short: powder coating is a more time-consuming process than its liquid paint counterpart. However, with that time investment, you can expect to see an attractive, durable finish that will last your products for years to come.
