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.
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 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.
Technological advancement has made it easier to apply this coating. The end product is usually beautiful with outstanding performance properties. Due to extended research in this area, modern day powders come with improved properties. This makes them more appropriate in serving their intended purpose. The properties of these powders change with time as the application changes.
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 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.
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.
