Those who are not fully familiar with powder-coating may be very surprised to learn the big advantages of choosing powder coating over traditional, wet paint. To begin with, powder-coating provides much thicker coverage; it is far more durable than conventional liquid paints; it has the ability to bend and flex without compromising the structural integrity of the coating; and a myriad of designs, textures and special effects can be achieved, which traditional paints simply cannot replicate.
Powder coating can be a superior finishing option for achieving unsurpassed durability and a more-professional appearance on an immense array of objects ranging from patio furniture, to motorcycle parts, to baby cribs, to hand-guns!
Let’s delve a bit more deeply into why powder-coating remains a superior alternative to traditional wet paint:
Powder Coating Is Much Kinder to the Environment
Powder coatings do not contain fluids that evaporate; and, therefore, will not emit any solvents. As a result, volatile organic compounds, known as VOCs, are not produced. This is important to the environment since VOCs are known to be health hazards to humans and animals in addition to being dangerous pollutants to land and water. Powder coating produces no waste-water discharge into sewer systems or ground water, and does not contain heavy metals or carcinogenic agents.
Did you know powder coating over-spray can, actually, be recycled? Unlike paint, powder-coating’s material loss can be kept under 5%, while 70% of paint is lost to over-spray during the application process. Only a miniscule percentage of powder coating is disposed of due to its high utilization rate; and the disposal process of unusable powder is very simplistic. Because of this, powder coating does not have to adhere to the same strict environmental controls that liquid paints do.
Powder Coating is Far More Flexible
Powder coating has the unique ability to bend and yield with the object to which it is applied; without the finish being compromised. The Bend Test comes into play, here, which is one of multiple tests that ensure performance reliability and quality control. With the Bend Test, powder coating is applied onto 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—a demanding role that powder coating can, easily, meet!
Powder Coating Offers a Noticeably-Thicker Finish
Powder coating offers a much thicker finish that wet paint. If we compare the physical properties, in terms of thickness-coverage between wet paint and decorative powder coat and functional powder coat, the variances are quite revealing:
*** Wet Paint: 0.5 – 1 mil
*** Decorative Powder Coat: 2 – 6 mil
*** Functional Powder Coat: 6 – 10+ mil
Powder coating beats wet paint, hands down! A powder-coated finish can last to last up to 20 years, providing superior durability that is unsurpassed.
Powder Coating Cures Much Quicker
When a powder-coated item is removed from the oven, the finish is completely cured within a mere 20 minutes, meaning it can be handled and used! Depending on the project, traditional liquid paints can require a number of days to completely cure.
After it’s all said and done, the advantages of powder-coating over liquid paint are quite stunning. Everything from military equipment, to appliances, to space satellites are powder-coated; and the reasons ‘why’, speak for themselves!
