What is powder coating?
Powder coating is a method of painting that uses a powdered polymer resin which is bonded to the part. At Central Powder Coating, we coat both ferrous and nonferrous metals using "Electrostatic Spray" equipment.

What does the powder coating process invlolve?
First, the part is washed and pretreated with iron phosphate and rinsed again with de-ionized water and sealer. Once the part has been pretreated it is dried in a dry off oven. The next step is the electrostatic application of the powder to the part. The powder is charged by an electrode which creates an ion cloud. The powder particles pass through this cloud and picks up a negative charge. Since the parts are ground to the conveyor there is an electrostatic attraction of the powder particle to the part. The parts now enter the curing oven where the powder melts, cross links, and bonds to the surface of the part. Once the parts exit the oven and cool the finish is complete.

What types of coatings are available?
Powder is available in a wide variety of formulations, textures, gloss levels, and colors. Common formulations applied at Central Powder Coating include; epoxy, hybrid, urethane and polyester. Depending on the performance criteria of your specific parts, we will be happy to help you pick the proper formulation for your application.

What colors are available?
Virtually any color, texture, and gloss level can be matched. We have several hundred colors of powder from DuPont, Cardinal and Tiger. Matching the color of powder coated parts to parts that were painted using traditional methods is no problem. However, due to the process involved in manufacturing the powder resin, custom colors can be expensive unless the requirement is large. Typical lead times for custom matches can range anywhere from two to six weeks depending on market conditions. Click on the links below for more information on some of the stock colors available.

What is the lead time to powder coat my parts?
Our goal at Central Powder Coating is to complete your product and have it ready for shipment within 2-3 days of receiving your material. Depending on the availability of the materials required to process your order, lead times may vary.

Why powder coating is the smart choise...
Powder coating is an extremely attractive, durable, scratch resistant, chemical resistant, and UV resistant coating. Depending on the specific formulation applied, each of these properties will vary. In general, epoxies exhibit good mechanical properties but fare poorly in direct sun light. Urethanes and polyesters exhibit excellent weatherability. Unlike most liquid coatings there are no solvents to evaporate in the powder coating process. Powder coating is environmentally friendly since no VOC's are emitted into the air.

  • Parts are cured within minutes of exiting the oven.
  • Powder coating provides superior edge coverage.
  • Excellent part to part color consistency.
  • Since powder coated parts virtually have no drips, runs, or sags, the reject rate is very low.
  • No paint sludge has to be disposed of because powder can be reclaimed and recycled, thus minimizing the impact on the environment.
