Powder coating is a dry coating process used as a metal finish mostly on industrial equipment. Powder coating is applied as dry powder through an electrostatic process, then cured with heat. It is well known for providing high-quality finishes in terms of both functionality and overall look.
The powder coating finishes are not only sturdy but flexible as well. It can be used on different surfaces, including metal, concrete, steel, and plastic. It’s suitable for both indoor and outdoor applications, and it’s one of the most cost-effective finish options.
Applications of Product
Preparation is the first step of the process and perhaps the most important one. This step determines how well the powder coating adheres to the metal surface, and there are various options for cleaning and prepping the surface. Using a degreaser and/or phosphate rinse is ideal, followed by a quick water rinse. The powder is then applied using the spray gun, and curing begins right after that.

Powder coating is based on polymer resin combined with pigments, curative, flow modifiers, leveling agents, and several other additives. All ingredients are melt mixed together, then cooled and ground into a powder. Preheating achieves a uniform finish, and cooling helps form a hard coating.
The powder coating process eliminates overspray wastage that may be experienced with solvent-based paints. Powder coatings are different from paint in the fact that they need an electric charge to work, while paint needs an adhesive.
An electrostatic paint sprayer is used for the application process. It imparts a positive electric charge on the powder and accelerates it towards the components through an electrostatic charge. The chemical bonding process strengthens the powder coating because once cured, the bonds solidify.
One of the most significant advantages of using powder coatings is that once solidified, more layers can be added id thickness is desired. Thicker coatings mean longevity and increased protection. Powder coatings are suitable for metal because they repel corrosive materials, such as chemicals and water.
