Powder coating is a finish option that gives a professional, sleek appearance to a variety of products. It can be used on anything from furniture to travel coffee mugs and water bottles to motorcycles. Even if you don’t realize it, the odds are good that you’ve seen powder coating numerous times. In this guide, you’ll learn more about what powder coating is, how it works, and why it’s a good option for just about any project you want to do!
What exactly is a powder-coated finish?
There are actually two types of powder coat finishes: electrostatic applications and fluidized applications. Although the processes are different, the final product has the same beautifully polished appearance. Both types of powder coats have to be baked in ovens that are heated to a minimum of 385 degrees Fahrenheit in order to set properly.
It is important to know that powder coating and electrostatic painting are not the same finish. These are two different types of product finishes that, while somewhat related, are used for different purposes and have different final looks, especially to trained eyes.
What ingredients are in powder coating?
Powder coating products all contain many identical ingredients. While some ingredients may differ from one brand to another, you can expect there to be resin in the form of polyester or epoxy, a curing agent of some sort, dyes or tints to give the powder coat its color, and “extenders” that are meant to make the powder coat as durable as possible.
Every type of powder coating also has various additives that do everything from give the finish its glossy top coat to improving hardness.
How do electrostatic and fluidized powder coating differ?
Electrostatic powder coating makes use of an electrostatic charge and a low-pressure application gun to evenly distribute the powder coat material over metal. Then, the product is baked to achieve its hard, glossy finish.
The fluidized powder coating method, on the other hand, uses forced air in a vat. The pressure behind the air causes the powder coat material to function as a liquid. In this case, the thickness of the final powder coat depends on how long it is exposed to the coating material. Once the desired thickness is reached, the product is baked just like in the electrostatic technique.
How can powder coating be used in home renovations?
Since the powder coating process can be done to any product that can withstand the baking temperature, the possibilities are nearly limitless. In-home renovations, powder coating can be used to give appliances, such as refrigerators, dishwashers, and microwaves, furnishings, and even picture frames brand new life.
If you are thinking about trying powder coating, make sure you know what you are doing! In most cases, it is best to hire a professional who has experience using this type of finish. Otherwise, you run the risk of being unhappy with the final result.
Powder coating is a versatile, durable finish that can transform the look of hundreds of household items, saving time and money for homeowners in the long run.
