Powder coating is an alternative way of coating surfaces with paint. Powder coatings are considered 100% solids, yet unlike liquid coatings, they do not require solvents in their formation. This is what you need to know about powder coating:
What is Powder Coating?
Powder coating is a dry coating procedure that is mostly utilized on industrial equipment as a metal finish. An electrostatic method is used to apply the powder coating as a dry powder, which is subsequently cured using heat. It is well-known for producing high-quality finishes, both functionally and aesthetically.
Powder coating finishes are not only durable but also adaptable. Metal, concrete, steel, and plastic are among the surfaces it can be used on. It’s a versatile finish that can be used both indoors and out, and it’s also one of the most cost-effective possibilities.
The Application process
Despite the fact that powder coating and liquid paint are applied in distinct states (liquid versus solid), the industrial application processes for both are remarkably comparable. In both procedures, the pretreatment is the same. The surface must be thoroughly cleaned before any coating can be applied. Surface adhesion will be hampered by any oil, dirt, moisture, or other pollution.
Dry powder is sprayed onto the metal exterior with an electrostatic gun during the powder coating process. The powder receives a negative charge from the gun, which attracts the negatively charged powder to the grounded section. As a result of the attraction, the application is quick and even.
The coated object is placed in a curing oven once the coating has reached the proper thickness, where the heated powder gels. Curing the powder forms heat connections between the particles, resulting in a smooth, hard finish.
How Long Does it Last
The product’s lifetime will be determined by a number of elements. The quality of the preparation, the type of powder coating utilized, and the environment in which the product is exposed are all elements to consider. Powder coating can last up to 20 years. However, they may deteriorate faster owing to frequent use, UV exposure, and exposure to the elements.
Powder coating is a great alternative to traditional methods. It uses an electrostatic charge to adhere to surfaces, and the result is exceptionally durable. Do yourself a favor and consider powder coating for your next project.
