One of the most common finishing methods in the market today is powder coating. It is categorized under dry finishing processes since it uses dry powder and does not utilize any liquid medium. It is gaining popularity throughout the world and mostly in the United States. It was introduced in the United States in 1960s and today, it is among the fastest growing finishing methods. When in search of Powder coating Manitoba must be given priority.
As a finishing method, powder coating represents about 15 percent of the total industrial finishing market. Many companies specifically demand to have their jobs done using this method because of improved efficiencies, simplified environmental compliance, and maximized production. The finish that is produced by this method is usually durable and of high quality. As such, this process has a great future as an industrial application.
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.
The application of these kinds of coatings has been made even easier by advancements in technology. The final finishes are normally aesthetically appealing and possess good performance qualities. Additionally, further research in this line has led to development of modern powders with improved properties. As such, they are more suitable for the purposes they are intended for. The changes in applications also correspond to changes in the properties of the powders used.
Powder coatings contain several different additives that make them to perform and behave the way that they do. They are usually based on polymer resin systems, which are combined with several additives such as curatives, leveling agents, pigments, and flow modifiers among many others. The production process involves melt-mixing all the ingredients and then cooling them before they are ground to produce a uniform powder. The powdery substance produced looks like baking flour.
The method by which powdery substance is applied to surfaces and substrates is known as electrostatic spray deposition. Application of the powdery substance is done using a spray gun. This gun is used to charge the particles to enable them be attracted towards the substrate or surface. The substrate in this case is commonly grounded. The substrate and the particles mostly do not have a strong enough bond and as time goes by the bond weakens
Upon weakening, the powder particles may fall from the substrate. This is avoided by subjecting the substrate to a curing process in an oven. In the oven, the powdery substance is melted then given time to cure onto the substrate. This results into a coat that is both uniform and smooth. The substrate is then taken out of the oven once is has cooled enough.
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.
