The History of Powder Coating

Posted on: August 28th, 2014 by byersbushblog

Powder coating has made an impact in many industries. From architecture and design to manufacturing and automobiles, this finishing process has changed the way the world looks. This finishing style made its debut shortly after World War II and has continued to change as technology changes. Here is a quick history of powder coating:

Early Days in the Post-War Era

Powder coating originated in the post-war time in the late 1940s. At this time, organic polymers (organic molecules that stick together) were sprayed onto metal bases, but in a powdered form using a flame spray. A German scientist named Dr. Erwin Gemmer was responsible for a 1953 process patent that explained the process of using a fluidized-bed to use a thermosetting powder coating operation. It took two years for his patent to be approved. Five years later, all powder coatings with a film of 6 mils to 20 mils used the fluidized-bed application.

In these early years, powder coating materials consisted of nylon 11, polyethylene, CAB, polyester, and plasticized PVC. Powder coating was mainly used to provide resistance to abrasion. It also helped keep objects from corroding and from being damaged from electricity. Some of the commonly coated objects in the early days include dishwasher baskets, which were coated in PVC; metal furniture, which was coated in PVC or CAB; and boat parts, which were coated in nylon. A German company named Bosch that developed the process for using epoxy resin to protect objects from electric currents. By the early 1960s, it seemed liked powder coating could not get any better, since all of the current problems were solved; but in reality, powder coating was about to see some major changes.

Mid-Century Modifications

In the 1960s, electrostatic processing was developed in the United States. This made the fluidized-bed process nearly obsolete. The Sames company made the spray guns and coined the term “Samesizing.” The late 1960s and early 1970s brought the four thermosetting resins that are still in the industry today. They include epoxy and epoxy polyester hybrid as well as polyester and polyurethane. At this same time, powder coating plants spread through many countries. For example, in Germany, there were ten times more plants in 1970 than there were in 1966. The rise in the industry was due to the fact that electrostatic processing made it affordable to use powder coating in nearly every industry imaginable.

The Sky is the Limit

The 1980s is the decade that sent the powder coating industry into the stratosphere. With advances in technology and the ease of obtaining materials, powder coating has become affordable for commercial and residential settings as well as for industrial and personal uses.

Now, powder coating is predominantly used in a handful of industries that include automotive and appliances as well as in general manufacturing. These industries enjoy using powder coating as attractive and durable finishes and the materials that powder coaters like Byers Bush use have become quite sophisticated. Industries continue to use powder coating because of the UV resistance, the clarity of color, and the ease of adhesion. Powder coating cure time is shorter than many think and the powder coating can be done by robots for large commercial projects.

As powder coating has developed over the decades, the uses for powder coated products has shifted through the years. The marketplace for products include the stock pieces that are used by the auto industry and are created in large batches. There is also a demand for small customized orders, too. As the equipment has become more affordable, powder coating is no longer limited to large factories and corporations.
