RapidDirect Powder Coating Services
We offer powder coating services to improve the strength and wear resistance of metal parts such as stainless steel, steel, and aluminum.
What’s Powder Coating?
Powder coating is a dry finishing process where a fine powder of pigment and resin is electrostatically charged and sprayed onto a metal surface. The charged particles adhere to the surface and undergo heat-curing to form a hard and durable coating.
Due to its uniform finish, many plastic and metal coating services recommend the surface finish process. Furthermore, powder-coated parts resist chipping, scratching, fading, and corrosion.
Powder Coating Specifications
| Applicable Materials | Colors | Glossiness | Cosmetic Availability | Thickness | Visual Appearance |
|---|---|---|---|---|---|
| Aluminum. Steel, Stainless steel | White, Black, RAL and Pantone | Glossy (Above 70 GU) Matte (Below 30 GU) | No | 50μm to 150μm | Results in a uniform, solid appearance that is both durable and smooth. |

FAQs
Many enthusiasts consider powder coating superior to liquid paint in several aspects. Powder coating offers better durability, coverage, and corrosion resistance compared to commercially available liquid paint. It also provides superior environmental benefits as it produces minimal volatile organic compound (VOC) emissions and is recyclable. Furthermore, powder coating produces a thicker, more uniform finish with no drips, runs, or sags, resulting in a more attractive and consistent appearance.
The duration of the powder coating process typically takes about four hours, but this can change depending on several factors. For example, smaller parts may require less time than larger parts due to differences in surface area. Similarly, the type of powder coating materials used, such as epoxy, polyester, or polyurethane powders, can influence the curing time.
Additionally, the part complexity, including shape and design features and pre-treatment requirements and curing oven capacity can determine the overall time needed.

Yes, preparing your part by blasting before powder coating is essential to ensure proper adhesion and a high-quality finish. Blasting helps remove rust, scale, old coatings, and other contaminants from the surface, creating a clean and smooth substrate for the powder coating to adhere to. By thoroughly blasting the part before powder coating, you can ensure even adhesion of the coating which will result in a durable and long-lasting finish.
Chipping or scratching can compromise the integrity of a powder coating finish, potentially exposing the substrate to corrosion or other damage. While properly applied powder coatings are durable and resistant to chipping and scratching, severe impacts or abrasions can still cause damage. However, touch-up options are available to repair minor damage, such as small chips or scratches, to maintain the coating’s integrity and appearance. These touch-up methods typically involve applying a matching powder coating material to the damaged area and curing it to blend seamlessly with the surrounding finish, ensuring continued protection and aesthetics.
Yes, it is possible to powder coat materials beyond just metal, including wood, plastics, and ceramics. However, they may need specific preparation and application techniques to ensure optimal results on non-metallic materials. Hence, consulting with a professional service provider like RapidDirect can help tailor solutions to meet the unique requirements of powder coating wood, plastics, ceramics, and other materials, ensuring a high-quality finish and long-lasting performance.
