Powder coating is a mixture of polymer resin, flow modifiers, leveling agents, and other additives. The ingredients are melted, mixed, cooled, and then finally ground into powder.
For the application process, we use an electrostatic paint sprayer. It provides a positive electrical charge on the powder, which gets applied to your metal parts.
Due to chemical bonding, the powder coating gets stronger once it’s cured because the bonds solidify. You can also add more layers to your powder coat if you want. Thicker layers mean added protection for your metals.
Powder coating is excellent for application in pretty much any project. Understandably, it’s hard to step out on a limb and try something different because you don’t know what will happen.
However, more businesses are switching to powder coating due to its many benefits. Here are a few.
Most paint projects come with a few hurdles like fading, chipping, bubbling, peeling and runs. With power coating,
once your metals have been sprayed and cured, they becomes highly resistant to wear and tear no matter what you put it through. You’ll no longer have problems with chips, scratches, or fading.
Due to its high-resistance capabilities, powder coating is perfect for metals that come in constant contact with sunlight and other environmental factors.
A common question we get about powder coating is, “How long does a powder coat finish last?” The answer is roughly about 20 years (depending on some external factors).
Since powder coating increases the durability of your metals, they are easy to maintain. That doesn’t mean they won’t get dirty. Dust and other factors can decrease the aesthetic of your metals or decrease overall resilience of the finish.
Through power washing and regular scrubbing your coating will remain intact and with a consistent finish. With this easy maintenance, you can use your parts for extended periods without worrying about damaging accumulating.
A big reason why people prefer powder coating over painting is because of its eco-friendliness. Although the powder is sprayed onto a metal part, there aren’t any chemicals involved to make it stick.
The electrical charge makes sure the powder coating sticks, removing the need for solvents and adhesives. Any residual powder can be cleaned up quickly, unlike paint.
Powder coating also doesn’t involve the use of volatile organic compounds (VOCs). What is a VOC? They are gases that get emitted from certain chemicals we use, such as:
Paint
Cleaning products
Varnishes
Ink
VOCs are harmful to the environment and linger in the air, causing individuals to come in contact with air pollution. That’s why painting gets broken down into chunks.
Since there are no volatile organic compounds in the dry powders used in powder coating, it is a better option for your metal parts. You won’t have to worry about inhaling any dangerous chemicals.
So not only do you protect yourself, but you also reduce your carbon footprint and help the environment in the process. It’s a win-win.
