Powder coatings have several advantages, which makes them an excellent choice for metal fabrication. OTHER ADVANTAGES OF CHOOSING POWDER COATINGS Epoxy coatings, on the other hand, may last very long indoors, but once exposed to the outdoors, they break down a lot faster. They are designed to withstand extreme conditions and are better suited for outdoor products. For instance, coatings that have fluoropolymers and urethanes can last longer. Powder coating finishes can last up to 20 years, but due to the consistent use, exposure to UV light, and outdoor environment may break it down faster.ĭifferent coatings also have varying lifespans. These factors include the quality of preparation, type of powder coating used, and the environment in which the product is exposed. The longevity of the product will highly depend on several factors. HOW LONG DO THE POWDER COATING FINISHES LAST? It holds well to extreme weather and physical impact, meaning it’s resistant to scratches, abrasions, and chips. The chemical bonds give a superior coating that makes it suitable for both machinery and everyday items. This is hands down one of the most durable coatings you could use as a finish for a variety of surfaces, not just metal. Powder coatings are suitable for metal because they repel corrosive materials, such as chemicals and water. Thicker coatings mean longevity and increased protection. One of the most significant advantages of using powder coatings is that once solidified, more layers can be added id thickness is desired. The chemical bonding process strengthens the powder coating because once cured, the bonds solidify. It imparts a positive electric charge on the powder and accelerates it towards the components through an electrostatic charge. Powder coatings are different from paint in the fact that they need an electric charge to work, while paint needs an adhesive.Īn electrostatic paint sprayer is used for the application process. The powder coating process eliminates overspray wastage that may be experienced with solvent-based paints. ![]() Preheating achieves a uniform finish, and cooling helps form a hard coating. All ingredients are melt mixed together, then cooled and ground into a powder. Powder coating is based on polymer resin combined with pigments, curative, flow modifiers, leveling agents, and several other additives. There are other methods that may be used, but they are only suitable for specific projects. The powder is then applied using the spray gun, and curing begins right after that. Using a degreaser and/or phosphate rinse is ideal, followed by a quick water rinse. This step determines how well the powder coating adheres to the metal surface, and there are various options for cleaning and prepping the surface. Preparation is the first step of the process and perhaps the most important one. This type is much cheaper compared to thermoplastic. It is suitable for high heat areas because the bonds prevent it from melting away. On the other hand, thermoset powder is quite different in the fact that it forms chemical bonds once cured, making it impossible to recycle it. For this reason, they can be used for a plethora of things from metal, auto parts, and even refrigerators. Thermoplastic coatings tend to be thicker, and hence more durable compared to thermoset coatings. This process makes the powder coating both reversible and reusable. Thermoplastic powder coating finishes become liquid and very soft when heated. There are two types of powder coating, thermosets and thermoplastics. It’s suitable for both indoor and outdoor applications, and it’s one of the most cost-effective finish options. It can be used on different surfaces, including metal, concrete, steel, and plastic. The powder coating finishes are not only sturdy but flexible as well. It is well known for providing high-quality finishes in terms of both functionality and overall look. Powder coating is applied as dry powder through an electrostatic process, then cured with heat. Powder coating is a dry coating process used as a metal finish mostly on industrial equipment. It brings improved durability, a reduced environmental impact, and a higher quality appearance. Powder coating, on the other hand, is a more advanced approach. Paint is a traditional approach with various limitations. To paint or to powder coat? What’s the best finish for your metal fabrication? Why choose powder coating finishes over paint?
