Powder Coating FAQ

Frequently Asked Questions

J.R.’s Commercial Cleaning DOES NOT provide powder coating services. The questions and answers on this page are for information purposes only in order to help you better understand the powder coating process.

What is Powder Coating?

Powder coating is the application of a dry, powdered resin to a surface. The resin is typically a thermosetting (polyurethane, acrylic, epoxy, etc.) or thermoplastic (nylon, vinyl, etc.) resin which is electro statically applied to the surface of a part. Application is done with a spray gun or fluidized bed. The coated part is then heated and the melted resin flows to form an unbroken film. The electrostatic charge holds the powder particles in place while the part is cured in a 400-degree oven. The heat of the oven causes a chemical reaction to occur and the powder to cure, creating a highly durable finish. When cool, the film exhibits properties often exceeding those achieved by conventional painting methods.

Is Powder Coating Environmentally Friendly?
Powder coating is an environmentally friendly process unlike solvent-based wet paint systems. With EPA regulations growing ever stricter, powder coating is fast becoming the technology of choice. Since the powder coating process does not use solvents in any way, VOC emission problems are eliminated.
Is Powder Coating Durable?
Powder Coatings resist cracking and peeling and are extremely abrasion, corrosion and chemical resistant. The performance characteristics of powder coating match or exceed the characteristics achieved from conventional solvent-based coatings.
What Can Be Coated?

Any metal object that can hold an electrostatic charge and withstand the heat of the curing process can be powder coated. Powder can be applied to intricate surfaces and still maintain a uniform finish across the entire piece. Powder coating is ideal for items such as:

  • Industrial Fabrications
  • Architectural Signage
  • Trade Show Exhibits
  • Metal Fencing and Railings
  • Retail Displays & Fixtures
  • Patio Furniture
  • Motorcycle Frames Wheels & Parts
  • Automotive Frames Wheels & Parts
  • Off Road Vehicle Frames & Parts
  • Bicycle Frames & Parts
  • Antique Beds, Gliders & Chairs
  • Large Bird Cages
What About Holes with Threads & Other Areas That Need To Stay Coating Free?
High temperature masking can be applied to special surfaces such as threads or high tolerance areas to keep them from being coated. We also use high temperature silicon plugs for threaded holes or shafts.
Can I Use Body Filler?
The high oven temperature makes the use of plastic and resin body fillers problematic. Often the powder will not bind to a filler’s surface causing bubbles in the coating. To be safe, fill any depressions with a torch using brass or welding rod as fill.
What is Clear Powder Coating?
Clear powder coating serves the same purpose as clear coat wet paint. It protects the underlying finish and adds depth and luster to the surface. Clear powder coat is applied as a second coat and shot while the piece is still hot. Then the piece is returned to the oven for a second curing process. Use clear powder coating on any piece that exposure to elements could cause it to fade or be subject to damage.
