The dry finishing process that is used in the industrial sectors has become very popular. This is considered to be of very high-quality the product that has a durable finish. This is basically used as both functional as well as decorative finishes. It is also available in a wide range of colors and textures. This process is known as powder coating. The powder coating is a very unique way of finishing techniques and is used in the industrial sectors. The technological advancement has resulted in the excellent performance of this process.
Working of the powder coating
The powder coating consists of polymer resin systems that have curatives, flow modifiers, pigments, and other additives. These ingredients are melted, then cooled and grounded to a uniform powder that is almost similar to baking flour. There is another process called electrostatic spray deposition that is also used to achieve the application. This application uses a spray gun that is applied to the electrostatic charge to the particles that have been powdered. The coating reacts chemically to produce quite long molecular chains. This is the most common method to apply powders and powder coatings can also be applied to non-metallic substrates.
Where is the powder coating used?
The use of powder coating is mainly done by the appliance industry mainly on the front side panels of the ranges or the refrigerators. This has also replaced the porcelain enamel on many of the parts of washers and dryers.
The automotive industry also uses the powder coating Melbourne especially on wheels, or door handles or bumpers, etc. The clear powder that has been developed is used to protect the auto bodies.
The use of this coating is very much used in architectural buildings. Here it is used on the aluminum extrusions that are for frames of doors and windows. The coating is also used for modular furniture.
What are the benefits of powder coating?
It has many benefits like:
It is highly durable and possesses resistance to abrasion and corrosion. It is incredible as compared to the liquid coatings. There are many companies that add compounds to the powder coating in order to enhance the anti-corrosive and anti-abrasive properties. This also helps to maintain the quality of the coating for quite a long period of time.
The powder coating lasts for almost many years and hardly fades with time. Even though it is exposed to UV radiation, the quality does not deteriorate over a period of time.
The best thing about powder coating is that it is available in a variety of colors and finishes. This, of course, depends upon the need of the application of the coating. It is very much possible that powder coatings are used for metallic as well as high and low gloss. The clear finishes are only possible with powder coatings.
The coatings that are based upon solvents may emit volatile or toxic compounds into the air. But this is not possible with the use of powder coating. This can be harmful to the workers who have not taken proper precautions as well as to the environment. On the other hand, the use of powder coatings emits hardly any toxic compounds.
These coatings are very beneficial and do not require a lot of training and cleanups. This is an almost inexpensive option if you seriously consider the quality and durability of the product.
Powder coating protects the toughest and the roughest machinery. This gives a much more durable finish which is also very attractive. powder coating is a popular choice more because it is resistant to the diminished coating that may result due to moisture, chemicals or any other extreme weather conditions.
