Powder coating is an art and a science. It takes experience, skill, and a great eye to guarantee perfect results every time. We’ve got all that covered. Here’s how the process works, and why you should choose powder coating over wet paint. Click the + for more info.
A perfect finish
Here’s how powder coating works.
Parts to be powder coated are prepared as appropriate for the material, using a multi-stage pretreatment and media blasting
if necessary. This insures an ideal surface for coat adhesion. Areas not to be powder coated are masked, capped, or plugged.
Ground and Charge
Electricity is our friend. After racking, the part to be coated is electrically grounded, and the powder is electrostatically charged.
Charged powder is sprayed onto the part. The grounded part naturally attracts the powder evenly and consistently.
After powder application, the part is heated in an oven. The powder melts, flows, and is fused permanently to the part.
Sorry, wet paint. Powder coating is better.
There are almost endless reasons why powder coating trumps painting. Here are some.
Powder coating is applied thicker than wet paint, with no runs or sags. The thickness difference is approximately four times greater than wet paint, due largely to the fact that wet paints are solvent based to acquire the necessary viscosity for wet spray application. The other driving factor is that powder paint is electrostatically charged and adheres strongly to the electrically grounded part to be painted. No thinning solvents are required.
Powder coating easily covers the most complex shapes, and is great at hiding imperfections in the base part. Powder-coated finishes are consistent, uniform, and free from common wet paint flaws like fish eyes and orange peel. The finish retains its color and gloss over time, and a vast variety of colors, finishes, and textures are available without the need for special painting techniques.
Powder coated finishes are highly resistant to all forms of wear, including scratching, fading, chipping, and corrosion. Powder coats are chemical resistant and good electrical insulators. This can be attributed to using a high quality powder paint and having very thick coverage.
Unlike paint, powder is free from volatile organic compounds (VOCs) and polluting solvents. Far less hazardous waste is generated by powder coating. Any excess powder can be recycled, resulting in near-zero waste.
Plus, thousands of choices of color, finish, and texture.
