Powder coating is one of the finishing processes that are in wide use today. This method is classified as a dry finishing process because it does not make use of any liquid medium. Instead, only dry powder is used. This method has continued to become popular in the entire world, especially in the United States. Its introduction in the United States first occurred in the 1960s and it is one of the fastest growing finishing methods in use today. When in need of Powder coating Manitoba should be visited.
In the entire industrial finishing market, powder coating represents around 15 percent. Most companies prefer having their jobs performed using this process because it capitalizes on production, it is ecofriendly and more effective. This method produces a durable and high quality finishing, giving it great potential in industrial use.
The powders used in the technique have two major functions. First, they are decorative. Second, they provide a protective finish. When serving as a protective layer, the coat protects the surface against tear and wear caused by use or by elements of the weather. The coat gives objects and surfaces a beautiful look when they are applied as a decorative finish. As such, the coatings are available in a wide range of colors and textures.
Advancements in technology have made the application of the coatings easier. The resultant finishes are usually beautiful and they possess excellent performance properties. Modern powders have also improved in their properties due to further research in this field. That makes them more suitable for the purposes that they are intended to serve today. As applications change over time, so do the properties of the powders in use.
There are a number of additives in these powders which make them work the way they do. They are normaly created on polymer resin systems which is combined with other several additives including leveling agents, pigments, flow modifiers and curatives among others. During production all ingredients are melt, mixed, cooled then ground to give a uniform powder. The end result resembles baking flour.
The powder is then applied through a technique known as electrostatic spray deposition. Electrostatic spray deposition is done using a spray gun. The gun charges the powder particles forcing them to be attracted to the substrate. Normally, the substrate is grounded. The bond between the substrate and the particles is not a strong one. As such, it weakens with time.
When the bond weakens, the particles may fall off from the substrate. To prevent this from taking place, the substrate is taken through a process of curing. Curing is done in an oven. The powdery substance is heated until it melts and then it is allowed to cure in place, forming a uniform and smooth coating. After cooling, the substrate can be taken out of the oven.
The process of powder coating is always offered by service providers as a service. These service providers may be companies or individuals. A person may choose to hire the services of a contractor and have them perform whatever an individual wants to be done. Powder coating is more costly when compared to liquid-based painting but it is worth the cost since it is more durable.
