About Powder Coating
Powder coating is the electrostatic application of a dry powder to a metal product. Post application, the powder is cured under heat to form a hard and durable finish, whether it be for decorative or protective purposes. Powder coated surfaces are more resistant to wearing, fading, chipping and scratching as opposed to those covered with a conventional liquid coating.
Though there have been significant advancements in the application of powder coating to other materials such as wood and glass, various types of metals are the most common material to be powder coated, because it can withstand the temperatures needed for the powder to cure.
Galvanised products can also be powder coated and the zinc layer applied to prevent oxidation may aid in prolonging part life.
Powder coating does provide a more resistant “skin” barrier, but it is important to remember that no finishing technique is completely impervious to the elements so rust, cracking and peeling, fading, chipping and scratching can still occur over time.
It is therefore very important to take the necessary steps, as far as possible, to regularly clean your powder coated product and to limit its exposure to the elements.
