Powder coating, inherently, offers a myriad of benefits over conventional liquid coatings. Powder coating: 1) is more cost-efficient 2) is more environmentally friendly 3) offers thicker and more durable coverage 4) will flex and bend with the material, to which, it is applied 5) offers less wasteful over-spray 6) can create designs and textures and 7) provides a more-professional appearance.
Out of all the advantages that powder coating offers, let’s take a closer look at three of these reasons which would justify powder coating being the superior option when it comes to adding unmatched beauty and durability to automotive rims, patio furniture, appliances, iron gates, medical equipment and so much more!
Powder Coating is More Environmentally Friendly
The environmental benefits of using powder coating are impressive. To begin with, since powder coatings do not contain any fluids to evaporate, powder coating does not emit any solvents. This means volatile organic compounds, known as VOC’s, are not produced. VOC’s are known to be health hazards to humans and animals as well as cause harm to the environment, with industrial pollution being only one of them.
Powder coating does not contain heavy metals or harmful cancer-causing agents. This amazing medium produces no waste-water discharge into sewer systems or ground water. Interestingly, powder coating over-spray can, actually, be recycled. As a result, material loss can be kept under 5%, while 70% of paint is lost to over-spray during the application process. Over-spray from paint is virtually impossible to collect and recycle. Since very little of powder coating is disposed of due to its high utilization rate, and since the disposal process of unusable powder is very simplistic, any miniscule amount that does need to discarded is not subjected to the same strict environmental controls that liquid paints must adhere to.
Powder Coating Bends
It’s almost hard to believe that a colored finish on an object would have the ability to, quite literally, bend and yield with the object to which it is applied without the finish becoming compromised. This is an especially vital benefit in the transportation industry where products and components are subjected to a great deal of vibration and twisting.
The Bend Test is one of multiple tests that powder coating is subjected to in order to ensure performance reliability and quality control. It is with the Bend Test that powder coating is applied on a .036-inch thick, phosphated steel panel where it must easily withstand a 180-degree bend over a ¼-inch mandrel without cracking or flaking. Elasticity and resistance to deformation are vital attributes for powder coating products; and the Bend Test is specifically designed to assess those attributes.
Powder Coating Offers an Unsurpassed Finish
In spite of the fact that powder coating offers a much thicker finish than conventional liquid paint, running, dripping or sagging of the coating are not issues. To put the thickness factor into a clearer perspective, the physical properties of coverage between wet paint, decorative powder coat and functional powder coat look like this:
*** Wet Paint: 0.5 – 1 mil
*** Decorative Powder Coat: 2 – 6 mil
*** Functional Powder Coat: 6 – 10+ mil
Functional powder coating is used by consumers, both private and public, when super-enhanced protection is desired such as protection for space satellites, farm equipment or a refurbished antique car.
A powder-coated finish is considerably more durable than liquid paints, which allows powder-coated finishes to last up to 20 years. Powder coating’s durability is unsurpassed, providing corrosion and maximized protection from chipping, scratching and normal wear and tear.
