For Good Powder Coating Manitoba Offers A Recommendable Destination

By Kathleen Hayes


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.

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 method of application of the powdery substance to surfaces and substrates is called electrostatic spray deposition. This method is done using a spray gun. The spray gun usually charges the particles of the powder so that they can be attracted to the substrate. The substrate is usually grounded. The bond between the particles and the substrate is usually not strong enough, which makes it to weaken over time.

Weakening of the bond results to falling off of the particles from the substrate. To avoid such an incident, the substrate needs to undergo a curing process. This process is performed inside an oven. The powdery substance is always heated to its melting point and then given time to cure in place resulting to a smooth and uniform coating. After cooling has taken place, the substrate can now be removed from the oven.

This finishing technique is provided by service providers as a service to clients. The service providers can be companies or private individuals. Clients can get in touch with a contractor and have them handle their job as per their needs. Normally, it costs a bit more than liquid-based painting, but its durability compensates for the cost.
