Powder coating - the basics
Powder coating is a modern painting process whereby dry powdered paint is applied to a bare metal object and baked on in a high-temperature oven. It’s a common method of finishing everyday objects and is increasingly being offered as a finishing option for hand-forged ironmongery.
Application of the powder is by spray gun. There are two major methods of powder coating but they both work along the same principles. As the fine powder, usually epoxy or polyester, leaves the gun it becomes electrostatically charged and sticks to the item being sprayed, giving a very even covering. It is then cured in an oven at 400 degrees Fahrenheit for around 10 minutes causing the powder to melt and form an even coating.
