When using powder coating, all surfaces must be clean. Very clean. Depending on the type and quality of the metal involved, you can do things in the pretreatment phase that will lead to the best results.
Understanding Powder Coating
Powder coating is used for protective and decorative purposes. When a finish is powder coated, electrostatics are involved. The powder used in powder coating combines finely ground particles of pigment and resin, electrostatically sprayed onto a surface. Once the powder coating dries, the result is an attractive appearance and increased durability.
Steps Used in Powder Coating
The first step in powder coating is thoroughly cleaning the base metal. This process involves removing all paint, dust, and oils. Sanding, grinding, media blasting, or a chemical process completes this stage. A metal part can even soak in acetone or a similar cleaner to remove residual oils.
Should You Use a Primer When Powder Coating?
Powder coatings are known to be extremely durable and exceptionally resistant to corrosion. They can also withstand exposure to harsh UV rays. In some circumstances, a dual-layer is required to achieve the optimal appearance. Primer base coats are not always necessary. Depending on the circumstance, you can use a primer base coat for corrosion resistance. A topcoat can also improve the overall aesthetic appearance.
