When trying to choose the right coating for your project, you may find yourself wondering: what are powder coatings and how do they differ from liquid coatings? These are among the most frequently asked questions we hear — and today we’ll be focusing on the benefits of powder coating, along with what this finishing really is.
What are Powder Coatings?
Powder coating is a finishing process that is applied while dry. Its use has been steadily growing in popularity since the 1960s and now represents about 15% of the professional finishing market. Capable of being used on a wide variety of products, this finishing process has become the go-to for man companies due to its durability and efficiency. Coatings such as these are used to protect and to decorate. They can be found in many different colors and textures, depending on what you need.
How Does Powder Coating Work?
Powder coatings have a polymer resin base that is combined with pigments, flow modifiers, leveling agents, curatives, and any additional necessary additives. These are all mixed together, cooled, and then ground into a fine powder. This powder, when applied through a spray gun, is electrostatically charged — allowing it to adhere to the grounded piece onto which it’s being sprayed. After the coating has been applied, the piece is put into a curing oven, where the heat causes chemical reactions that make it much more durable, dense, and harder to destroy.
What Are the Benefits of Powder Coating?
Powder coatings are one of the most durable and long-lasting finishes on the market when it comes to finishing metals. Surfaces that are powder finished are more resistant to fading, chipping, scratching, and general wear, while the finishes themselves can come in either matte, satin, gloss, iridescent, or metallic, to name a few. The color will also last longer and remain more vibrant with a powder finish, and textures can range from matte to rough, enabling you to hide any surface imperfections should you need to.
Powder coatings are also very eco-friendly, as they contain no volatile organic compound solvents (VOCs). These chemicals, when released into the atmosphere, can have harmful effects on both the environment and on human beings who inhale the fumes. Whether your company is concerned about environmental impact or simply wants to promote consumer safety, these powder coatings may be the way to go.
- Reduced Costs
By eliminating VOCs, companies can be more in line with EPA regulations. This can help mitigate the risk of fines or fees that are associated with air pollution legislation that has become stricter in recent years.
So what are powder coatings? Powder coatings are a durable and long-lasting form of dry finishing that can be found in many different finishes, textures, and colors. It can be applied to many different types of metal or metal substrates and won’t run the risk of fading, chipping, or wearing out as time goes on. Additionally, it can help companies comply with government regulations while mitigating health and environmental effects on both a nationwide and local level.
