In today’s blog, we answer some frequently asked questions about powder coating.
What is powder coating?
A powder coating combines polymer resin, curatives, leveling agents, flow modifiers, pigments, and other additives as a dry finish that goes over metals and anything that can hold an electrostatic charge.
What is the purpose of powder coating?
Powder coating protects metal equipment and household items from wear and tear due to sunlight exposure, moisture, humidity, corrosion, oxidation (rust), and more. It makes coated items last longer while possibly preventing breakdowns.
How long does powder coating last?
Powder coating may last up to 20 years, depending on the conditions in which the coated item operates. Consistent use, frequent exposure to ultraviolet light, and constantly being in an outdoor setting might make the coating break down faster. Different types of coatings have various lifespans.
What is the process of powder coating?
Powder coating involves several steps that apply a powder to a metal using electrostatic properties:
Small parts are hung in a row, ready to receive powder coating. Large items sit on the floor. Components hang on metal hooks at about eye level.
A professional powder coating specialist wears personal protective equipment. The technician hooks up an air hose to a canister containing the powder, called a feeder unit. Then the powder travels through an air gun that regulates the flow of the powder. The feeder unit also imbues the powder with an electrostatic charge, allowing it to adhere to the substrate easily.
Following an even coat of powder, every piece goes into a specially designed curing oven—items with a powder coat cure for 20 to 45 minutes at around 400 degrees Fahrenheit. Curing the powder promotes adhesion of the powder to the substrate, and it activates the protective skin that keeps items safer from corrosion.
What substrates can powder coating adhere to?
It can adhere to any substrate that can hold an electrostatic charge:
- Metals like iron or steel
- Wood, in some cases.
Is powder coating better than paint?
Yes, in many ways. That’s because the coating permanently bonds to the surface of the item receiving the coating.
How much does powder coating cost?
The cost of powder coating depends on the part’s size, how many, the coating type, and transportation costs to and from the facility.
