Powdering Coating

powder coating, a dry finishing procedure, has become extremely popular ever since it was first introduced in North America during the 1960s. Its popularity is such that it is nowadays used to coat a wide variety of products. Based on statistics, this type of coating encompasses nearly 15% of the entire finishing market. Thanks to its quality finish and long life, an increasing number of companies nowadays specify this coating for their products as it provides an excellent quality and durable finish. This allows for improved efficiencies, simplified environmental compliance, as well as for maximized production. Used as decorative and protective finishes, these coatings are available in a wide array of textures and colours. Advancements in technology allow this method of coating to provide exceptional performance properties on the coated surface.

How does this coating system work?

The powder coating is based on polymer resin systems, which are combined with pigments, curatives, flow modifiers, pigments, levelling agents, as well as other additives. These ingredients are mixed after melting them, following which they are cooled and finally ground to a uniform powder that is quite similar to baking powder. A procedure known as ESD (electrostatic spray deposition) is normally used to accomplish the application of the coating to a metal substrate. A spray gun, used for the process, applies electrostatic charge to the fine powder particles that are attracted to the grounded part. Once the application process is over, the parts that have been covered with a layer of powder are inserted inside a curing oven, whose heat causes a chemical reaction on the coating, producing long molecular chains. This results in high cross link density. These chains are extremely powerful and quite resistant to breakdown. One can also apply these coatings to non metal substrates like medium density fibre board and plastics. The silver like shine on your mobile phones and other plastic objects is achieved through the powder coating process. The longevity of the coating depends on its thickness (measures in thousands of microns). The greater the density, the longer the coating will withstand wear and tear.

Is this coating durable?

This coating consists of a top quality finish you will find on numerous products you come in contact with every day. The biggest advantage of this type of coating is its ability to protect your household items as well the toughest and roughest machinery. Unlike other types of coating, this coating provides a finish that is much more durable than liquid paint can offer, and provides an attractive finish to boot. Products coated with powder are much more resistant to diminished quality coating because of ultraviolet light, chemicals, moisture, impact, as well as extreme weather conditions. This, in turn, reduces the chances of fading, abrasions, chipping, scratching, and other types of wear issues. If this is not enough, this type of coating is tough and durable. It lasts for many years and enhances the look of the item it is coated on. Apart from being durable, powder coating is also an ideal choice because of its environmental advantages.
