Powder coating is an alternative finishing method to liquid painting, where dry powder is applied to the metal through an electrostatic process, then cured with heat in a large oven. Just like wet applied coatings, powder comes in various types such zincs, primers, enamels, epoxies, polyesters, fluoropolymers, urethanes, and more. The result is a beautiful high-quality finish with excellent corrosion resistance.
It is easy to see why powder coating is a popular choice across many industries including automotive, marine, construction, architecture, and residential. However, powder coating has some limitations. It can be applied to metals such as wrought iron, aluminum, and steel, as long as it can withstand high temperatures 400°+ Fahrenheit without losing its integrity. This also means non-metal accessories such as plastic or rubber must be removed from the metal beforehand. For example, tires must be dismounted from rims before sandblasting and powder coating. Potential problematic substrates are chrome, galvanized, and cast parts, often leading to out-gassing. A limitation of powder coating arises for larger items that are not compatible with the oven size. With Citrus Sandblast’s oven stretching 30 linear feet, large pieces can easily be accommodated.
While powder coating has many advantages, there are some necessary actions to take to ensure the application of powder coating will live up to its reputation. Proper application of powder coating begins with cleaning the surface to remove any dirt, oils, moisture, or other contaminants that may prevent the powder coating to adhere properly. Abrasive blasting creates an anchor profile in the metal for the powder to integrate into when heated.
Just like powder-coated steel, powder-coated aluminum is incredibly tough and can withstand contaminants and moisture in the environment for many years. Nearly endless options of colors, textures, and sheens provide the ability to restore aluminum to its original appearance or opt for a new look. Citrus Sandblast provides powder coating aluminum services on patio furniture, gates, railings, fences, canopies, awnings, auto parts, oem parts, and more.
The choice between painting vs. powder coating should be based on a variety of factors. Ultimately, both painting and powder coating can provide a smooth, durable, and beautiful finish on a variety of surfaces. Still not sure which direction you should take with your project?
