How Does Powder Coating Work?

Powder coating is the process of applying a finish to a metal product.  It is similar to painting, but the medium is a fine powder that is sprayed on to the product.

Powder coating is a dry process; it uses a dry powder instead of wet paint.  The powder itself is made up of finely ground particles of pigment and resin that are electrostatically charged.  The powder is sprayed onto the product to be coated using a spray gun.

The product being coated is electrostatically grounded, and the powder is electrostatically charged, which makes it stick to the product.  Any excess powder that is over sprayed can be collected and reused.

After the powder has been sprayed on the product, it is baked in a very hot oven (around 400°) to cure it.  The curing process basically melts the powder, and then it hardens to a uniform and consistent finish.  The resulting product is high-quality and has an attractive and durable finish.

Benefits of Powder Coating Instead of Painting

Powder coating is preferable to painting because it is much more environmentally friendly.  Liquid paint contains volatile organic compounds, or VOCs.

These compounds are dangerous to the environment and our health.  The powder used in powder coating is extremely low in VOCs, so it is much safer to use.  No solvents are necessary, and it is safe to handle and can be disposed of easily.

Since excess powder can be gathered up and used again, it reduces waste.  Powder coating is so safe that there is no need for pollution control equipment.

Another benefit of powder coating is that it provides an extremely durable finish.  It is one of the most long-lasting and economical finishing choices available.

When a surface has been powder coated, it is resistant to chipping, scratching, and fading.  There are tons of color choices to choose from, as well as high and low gloss finishes, metallics, and clear coats.

Powder coated finishes retain their bright, vibrant color for longer than paint.  There are many texture choices available, as well; you can get a smooth, wrinkled, rough, or matte finish.

Myths about Powder Coating

  1. Powder coating will never chip.  This is not true.  Powder coating is resistant to chipping and is much less likely to chip than liquid coatings, but we cannot guarantee that it will never chip.  If the impact is hard enough, it may chip.
  2. Exposure to weather will make powder coating fade.  This is not true.  There are certain types of powder coating that are intended for extended outdoor use.  They are used in architectural applications, and can retain their color for more than 15 years.  If your item will be used outdoors for an extended period of time, talk with the professionals at the powder coating company about what type of powder coating is best for your application.
  3. UV exposure will make powder coating lose its gloss.  This is not true.  Powder coating offers excellent UV resistance.
