How Powder Coating Works

Powder coating is very much like it sounds in that a dry type of free-flowing powder coating is aimed at the object to be painted and adheres based on electrostatic charging that is then cured under heat. As a result of the process, the powder coating becomes a much stronger finish than conventional liquid paint, especially beneficial in outdoor uses and where the item may take an unusual amount of punishment such as appliances, chairs, bicycles, and numerous metal items. Liquid coatings need binders and fillers (solvents) to keep the liquid in suspension waiting for coating and requisite drying time in order to set.  Powder coatings do not require the solvents and thus, end up being stronger and more versatile. The result of applying the coating electrostatically is the formation of a skin that is allowed to set as a stronger, longer lasting coating than typical paint.
