Powder Coated Sheet Metal

What`s Powder Coating

Powder coating is a dry finishing process that has become extremely popular. Powder coating is used on a wide array of products. More and more companies specify powder coatings for a high-quality, durable finish, allowing for maximized production, improved efficiencies, and simplified environmental compliance. Used as functional (protective) and decorative finishes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties.

Advantages over other coating processes

1. Environment friendly. Powder coatings contain no solvents and release little or no amount of volatile organic compounds (VOC) into the atmosphere.

2. More thicker coatings without running or sagging than conventional liquid coatings.

3. Perfect color consistency. Powder coated items generally have fewer appearance differences than liquid coated items between horizontally coated surfaces and vertically coated surfaces.

4. A wide range of speciality effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.

5. Curing time is significantly faster with powder coatings compared to liquid coatings especially when using ultraviolet cured powder coatings or advanced low bake thermosetting powders.

Powder Coating Process

The Powder coating process involves three basic steps: raw material preparation or the pre-treatment, the powder coating application and curing.

Powder Coating Substrate Considerations

Before applying the powder coating material, you must first consider the substrate material that you will be coating. It is very important to have a clear understanding of the true composition of the surface of the part.
