Industrial Powder coating is a type of coating that is applied to industrial products as a free-flowing, dry powder. The main difference between a conventional liquid coating and a powder coating is that the powder coating does not require a solvent. It is usually used to create a hard finish that is tougher than a liquid coating. It is mainly used for coating of metals. There are many benefits of using powder coating compared to liquid coating.
There are several economic benefits offered by industrial powder coating. It is much more efficient than painting. About 95 percent of the powder material makes it onto the substrate while conventional paint results in about 35 percent. Much of this is due to the properties of powder coats.
Powder coating produces a coating twice as thick as standard paint. The real advantage is its flexibility and ability to bend and yield with the material it is applied to. This makes it ideal in the aerospace industry where the products are subject to a lot of vibration and twisting.
Safely applying industrial powder coating requires precautionary measures to avoid breathing in the powder and getting it on your skin. This is an easier task to manage since the product is a solid and inert. The product does not contain harmful chemicals such as solvents or volatile organic compounds that are often found in liquid coating.
Because of the evaporative properties of the liquid coating, there are always environmental factors to consider. Volatile organic compounds are gases that can have short-term or long-term adverse health effects upon those exposed to them. Liquid coatings contain these compounds. Powder coatings are solvent-free and contain no hazardous waste.
Powder coating is superior to liquid coating in the application. A single coat of this coating can produce a thickness of 2 to 4 mils while liquid coating will only produce a thickness of up to 1.2 mils. Powder coating can be completed in single coat with excellent edge coverage. Liquid coating often requires multiple coats, can show an uneven finish, and have poor edge coverage.
