What is Powder Coating?
Powder coating is a dry painting process that uses a fine powder with the consistency of powdered sugar, and an electrical charge to coat an object. Then the piece is baked in an oven at 400+ degrees Fahrenheit to make the powder melt and flow together. Once it is cooled and cured the powder coat has formed a solid plastic coating over the entire surface that is much more durable than regular paint.
How Does Powder Stick?
FASHION TITLE
The powder is sprayed through an electrostatic or cornea gun onto a metal surface that is grounded. The electrical charge given to the powder by the gun is attracted to the grounded surface of the metal. The coating is cured at a specified temperature; cure temperatures vary depending on the coating being applied. Until you bake it, the powder can be easily brushed off. It needs heat to make the powder flow and form a permanent coating.
How Durable is Powder Coat?
Powder coating is more durable than even baked on enamel in most applications. Powder coating is better protection against rust and corrosion, and resists scratching and chipping better than paints too. It is also much more resistant to chemical solvents too.
