Powder coating is a type of dry coating, which is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is applied electrostatically and is then cured under heat to allow the powder to harden and create the compact surface protective layer. There are several advantages of powder coating over conventional liquid coatings:
• Except the decorative function of Powder coating, especially on Carbon steel zinc plated surfaces, Powder coating remarkably improves the corrosion resistance.
• Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
• After hardening the coating layer excellently fulfils the requirements on Color lasting, Gloss stability, UV resistance as well as Abrasion and Impact resistance.
• After oven hardening, the coating stays flexible and absorbs even remarkable expansion of the supporting surface as well as its bending or twisting.
• Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
• Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating.

Quick and simple testing met hod to chec k the qualit y of the applied coating Bending the painted washer reveals defects in the compactness and flexibility of the powder coating layer under pressure. Standard pliers are used to bend the washer. When bent no visible crack should appear on the edge of the bending.(Modified bending test DIN EN ISO 1590)
