Powder coating is used to add a finish to the metals. Its flexible to work with, and many layers of coating can be applied to achieve the desired thickness. This kind of coating is seen on aluminium, steel, brass and zinc. The process of coating protects the original metal and makes it stronger by adding a coat over it. This has majorly helped objects from corrosion and damage that can happen due to acids, solvents and debris. The coating protects the object from electoral currents too.
Coating the object with powder doesn’t leave marks of the coating being applied horizontally or vertically. Using powder to coat objects is much better than using the liquid coating. Objects that require a thick coating to protect the surface should use a powder coating. Every bit of the coating can be utilised till the end. Objects that have a thin coat of powder on their surface are expensive, as thin coating gives a peeled texture. Every object has the desired number of thicknesses that they require. Some objects might need a coating of fewer than thirty micrometres, while some might need more.
Process of Powder Coating and Its Application:
To achieve the powder finishing, pigment and powder ingredients are mixed with the polymer granules. This mixture is then heated well, ensuring all the ingredients are dissolved. The mixture is cooled and made flat with the help of a roller, and later broken into pieces. These tiny pieces are crushed to form a powder. As different kinds of pigment can be added to the mixture, it can produce a variety of colours. The process is conducted by experts under supervision.
The thermoplastic material powder is heated when the powder needs to be applied to an object. The finishing of this material powder will help the powder coating to stick on the shiny surface of the metal. An electronic gun is then used to spray an equal amount of powder on the object. As the gun gives out an electronic charge, it helps the powder stick to the object. The object is heated, which makes the powder melt and stick to it, making it a hard coating. It requires a final cured coating, which is like applying two packs of wet paint. Because of the process of coating powder, the object is harder as compared to before.
Powder Coating Has Helped The environment in a huge way:
People are looking for eco-friendly alternatives that can contribute towards saving the environment. The process of coating powder is environmentally friendly, which makes it a far better choice than liquid coating. The process of the coating doesn’t emit any harmful compounds. It has no paint sludges that are left behind like seen in the process of liquid coating. No waste material is produced throughout the process, which could be dangerous to the environment. The powdering process doesn’t create harmful materials that will increase the pollution of air or water.
The cost of coating powder is affordable as its durable. It’s a very friendly choice and people should invest in objects that are coated with powder. There are a few other types of powder coating too that are done on certain objects, depending on their features and metal. People are purchasing products that have been coated with powder, as they can go on for many years. People must invest their money in objects that can provide them with a great experience, without destroying their health.
Powder coating is easy, affordable and long lasting moreover, it is good for environment thus opting for it has many benefits.
