Today, one of the most widely used finishing processes is powder coating. Powder coating is categorized under dry finishing processes since there is no liquid medium involved. The popularity of this technique is on the rise globally, especially in the US. This technique was first introduced in the US back in 1960s. Currently, it is among the fastest growing finishing techniques in use in the United States. When one needs Powder coating Manitoba offers the perfect location to visit.
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 that are used in this method are used to serve two major functions, that is, decorative and protective finishes. When used for protective purposes, the coatings are intended to protect surfaces from wear and tear that results from use and weather. As a decorative finish, the coatings are intended to make surfaces and objects look more beautiful. For that reason, these coatings come in a wide range of textures and colors.
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.
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.
Powder coating is a process that is offered as a service by service providers. Service providers may be individuals or companies. One can hire a contractor and have them do whatever one needs done. It may cost slightly more than liquid-based painting, but the durability makes it worth the cost.
