Powder coating is a dry finishing process that has become extremely popular for industrial and other applications since it was first introduced in North America over 40 years ago. Powder coatings have been used by numerous companies in giving their products a durable finish of high quality that minimizes maintenance, allows for maximized production, and facilitates environmental compliance. Our industrial powder coating applications withstand heavy use and provide maximum protection for products and components at lower prices than other types of coatings.
How Industrial Powder Coating Works
Polymer resin systems combined with curatives, pigments, flow modifiers, leveling agents, and other additives make up powder coatings. These ingredients are melted down, mixed, cooled, and ground into a uniform powder. Electrostatic spray deposition is then used to apply the coating to a metal object by means of a spray gun, similar to a paint gun. The powder coming out of the gun has a mild negative charge. The object itself must be cleaned and free of any dirt, grease, or oil, and connected to a small electrode, imparting a very mild positive electrical charge. Since the powder and the product have opposite charges, the particles of the powder will be attracted to the product.
A curing oven is then used where the powder coating chemically reacts to produce long molecular chains, which are very resistant. This process can be used for both metallic and non-metallic objects and substrates, such as medium-density fiberboard and plastics.
Durability of Industrial Powder Coating
At Secoa Technology, we enjoy finding solutions and pinpointing the perfect coating for the needs of our customers. We are able to make powder coatings in an almost limitless range of colors and textures, providing excellent performance properties.
In addition to being used on the toughest and roughest machinery, powder coatings are used on many household items that people use on a daily basis. They are more durable than liquid paints but are equally as attractive. The powder-coated products we have are more resistant to moisture, impact, ultraviolet light, chemicals, and other extreme weather conditions than most coatings on the market.
