Bus bars work as wonderful conductors and play an important role in the distribution of electricity. Without bus bars or with faulty bus bars, our electrical substations would be useless. Without the proper coating on copper bus bars, these integral pieces to our electric grid would not last as long as they should. At Coating Systems, we will add a layer of powder coating onto bus bars. As a coating company with decades of experience behind our name, we know the technical ins and outs of powder coating bus bars.
Why Should You Coat a Copper Bus Bar?
Though most people think coatings are only used for insulation, reducing heat, or lubrication, certain coatings also help prevent corrosion. Coatings with anti-corrosive properties are most often used in the aerospace and automobile industry, but bus bars also need to withstand corrosion.
When two different types of metals come into contact through an electric current, one will begin to corrode in a process known as galvanic corrosion. Many different, unique factors play a part in how, why, and which metal corrodes, but a good powder coating will reduce the amount of galvanic corrosion in your bus bars.

How Does the Powder Coating Process Work?
The powder coating process may seem like it shouldn’t work because we are coating a surface with a dry epoxy rather than a wet paint-like material. Powder coatings stay in place not because they dry and adhere to the copper bus bar, but because we give the epoxy or the ECTFE powder an electrostatic charge that allows the two surfaces to bond on a molecular level. Because we negatively charge the coating powder by passing it through a spray gun designed for that purpose, the powder bonds to the surface of the bus bar.
Think of it as an extremely strong magnet or as static electricity. Once we coat the bus bars, we bake them in an oven specifically made for this process. This keeps the coating in place. Because of its high level of conductivity, copper takes very well to coatings of this nature.
