Powder-Coat Extends Life Of Metal Parts
Chris Borning makes a good living powder-coating all kinds of metal objects – big and small – for farms and other industries. As a motocross racer in high school, he discovered powder-coated parts looked better and the finish lasted longer than paint. He went on to launch his business, C&L Powder Coating. He says his customers like the speed of the process and the durability of the coating.
  “As soon as the coated part comes out of the curing oven and cools, it is ready to go,” says Borning.
  Powder coating is a multi-step process. Older parts may be sandblasted, while new parts often go through an acid wash process. Then the powder is electrostatically charged to stick to the bare metal as it is applied. When the part goes into the oven, the powder liquefies and bonds to the surface.
  “The cure time is 10 min. at around 400°F," explains Borning. "Actual time in the oven depends on the thickness of the metal. Curing is achieved when the entire part reaches the required temperature for the full time."
  The size of the oven can be the limiting factor. C&L started out in 2009 with a 6 by 6 by 10-ft. oven. This past summer they added an 8 by 8 by 22-ft. oven to handle bigger jobs, like a request to coat 6 Deere tractor wheels.
  "The farmer had planned to get them painted, but decided to go with powder coating," says Borning. "We sandblasted them and applied a primer, top coat and clear coat. I put a 1-year warranty on the finish, but I expect he won't have to touch those wheels for 20 years."
  Borning explains that the number of coats and the powder used can depend on how the product will be used and where. He won't do an automotive wheel if the customer doesn't agree to all the proper steps.
  "Wheels take a lot of abuse and often don't get cleaned," he says. "If you don't go with the primer, color coat and top coat, you're asking for failure."
  Different powders offer different features, such as UV protection with polyurethanes, and rust and acid protection with epoxies.
  "We may use an epoxy primer with a poly topcoat," says Borning. "Acids won't eat through the epoxy, and you get the color you want with the poly, plus UV protection to keep it from fading."
  Color choices used to be limited, but that has changed. "One powder manufacturer has more than 6,500 colors," says Borning. "You can even get special textures like wrinkles."
  Special colors can also add to the cost. He notes that the yellow for the Deere tractor wheels costs around $9/lb. Each job is bid accordingly. The Deere wheels were approximately $150 each.
  Limiting factors to powder coating are the thickness of the part and the ability to hold it at the right temperature.
  Borning suggests that FARM SHOW readers interested in powder-coating should give him a call to discuss size, expected use and shipping. If considering other powder coaters, he recommends comparing the steps they follow and coats they recommend. He points out that not all powder-coating is the same.
  "I have a regular customer from Illinois who ships parts for us to coat," says Borning. "He went through 5 different powder-coating operations before he tried us and was satisfied. It is a matter of quality and the time the operator is willing to put into the job."
