Powder coating is a type of coating that 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 typically applied electrostatically and is then cured under heat in an oven to allow it to flow and form a skin. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is up to 10 times tougher than conventional paint. Powder coating is primarily used for coating of metals, such as aluminum, iron or steel.
What are the advantages?
*Superior durability, up to 10 times more durable than traditional wet paint.
* Powder coatings emit zero or near zero volatile organic compounds (VOC).
* Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
* Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating.
* Powder coating production lines produce less hazardous waste than conventional liquid coatings.
