What is Powdercoating?
Powder coating, commonly referred to as "dry" paint, is a method of applying a decorative and protective finish to most all metallic parts. The powder is a combination of finely ground particles of color pigment and resin. When applied, the powder is electrostatically charged using a special gun while the parts are electrostatically grounded. The powder uniformly adheres to the part which is then placed in an oven to cure. The result is a smooth, lustrous coating that is extremely durable, scratch and chip resistant.
Why Choose Powder Coating?
Powder coating is currently the single fastest growing coating technology for these reasons:
Powder coating is much more resilient to chips, abrasions, UV light, petroleum products (gasoline/oil) and chemicals than typical solvent based (“wet”) coatings.
Powder coating is thermoset, and withstands higher temperatures than solvent based coatings.
Because it is electrostatically applied, powder coating eliminates the possibility of runs and drips. The powder is environmentally friendly and there are no hazardous materials needed for cleanup.
How Are Parts Prepped For Powder Coating?
Depending on the condition the part is received, it may need to be stripped of all previously applied coatings down to the bare metal. This may be performed by Thermal Stripping, Media Blasting, Dry Abrasion, or a combination of these methods. All of these processes are performed by APS onsite.
All parts are washed with a metallurgical cleaner/rust inhibitor. After rinsing, the part is then charged into a propane fired oven, where it is dried at approximately 350 Fahrenheit for 20-30 minutes prior to powder coating.
APS masks and plugs areas that typically need to be protected from powder. Any special masking and plugging requirements will be performed upon request.
Should I Sand/Strip Excess Paint?
Unless you have the proper equipment, generally, it is not worth your time and effort.
If you have parts that are currently powder coated, we strongly recommend you not try to strip them. This process should be performed by APS.
I'm Interested In Just shipping my parts to APS for processing. How Does This Work?
We perform this service on a regular basis. We realize that your schedule may not allow you the time to personally deliver your parts. Simply package your project and ship to APS for processing. We recommend using UPS or FedEx for traceablity and tracking purposes. Your job will be processed, repackaged, and returned to you, generally via UPS. Packaging and shipping costs will be added as a separate line item on your final invoice. A tracking number will also be on your invoice. If you have any questions, please call us for more details.
