What is Powder Coating?
Powder Coating is...
...a type of dry-finishing used by manufacturers for coating metal products such as household appliances, aluminum extrusion, drum hardware and automotive parts. The reason manufacturers are using powder coating over traditional liquid paint is that it provides a tougher finish that last longer.
Benefits of powder coating include:
Powder coating provides a more durable finish than liquid paint, making the products more scratch resistant and long lasting.
The process of powder coating is environmentally friendly, it produces little to no VOCs.
Powder coating production lines produce less hazardous waste than traditional liquid coating.
What is the process?
Powder coatings are a combination of polymer resins, curatives, pigments, leveling agents, flow modifiers, and other additives that are melt mixed, cooled and ground into a flour like consistency. To apply this powder, a process called Electrostatic Spray Deposition (ESD) is used. This process charges the paint particles, which encourages the powder to adhere to the grounded metal part. Once the powder particles are on the metal part, it is then placed into a curing oven where it is baked, which creates long molecular chains, resulting in a high-crosslink density. This process makes the coating strong and resistant to breakdown, and the result is an attractive, durable, high-quality finish.
What makes this process unique is that it is environmentally friendly, the process has no hazardous byproducts or waste. Unlike liquid paint, no solvents are used in the powder coating process, which means that only negligible amounts of VOCs are released into the atmosphere. In addition, unused or over sprayed powder can be recovered, so any waste is minimal and can be disposed of easily and safely.
