Powder coating is a form of metal finishing that's applied in dry powder form. Unlike traditional liquid paint that's delivered through an evaporating solvent, powder coating must be applied using a special electrostatic charge, usually generated by a welding process. Once the charge is generated, the coating liquid is spread across the metal and is held there until it is cured. When the curing process is complete, the coating material is completely cured and becomes weather-resistant. This allows it to be used in a variety of situations where high durability and toughness are needed for products.
There are many benefits of powder coating at this site. Among them is the fact that the finish is extremely durable and can't be easily chipped, peeling, flaking, or damaged. Because the product is so tough, it also provides excellent resistance to abrasive cleaners, oil, and grease. Also, some types of metals will not scratch when exposed to the regular wear and tear of typical use. For these reasons, many different industries use it to protect their equipment and machinery from damage and staining.
Originally, the most common metal finishes used in powder coatings were zinc and nickel based. However, recent technological advances have made it possible to coat other metals with similar results. Many other types of powders are now being manufactured, including PVD (poly Vinyl Deforme) powders, aluminum powders, and even ceramic powders. Each of these various powders has different properties and effects to the end user.

In order to coat metal parts, the simplest way is with zinc or aluminum powder coating tools. These tools produce fine grains that adhere more closely to the metal surface than other types of tools. Although fine grain powder coating does not provide as much protection as other types of products, it is still a useful coating for the craftsman. Zinc powder coating products can be used on indoor and outdoor crafts in the same application. Be sure to read more here!
There are two types of powder coating systems, hot dip galvanizing and cold dip galvanizing. Hot dip galvanizing uses electric currents to flip the particles onto the surface. Cold dip galvanizing uses water jets or air blowers to heat the particles on contact. Both systems create a fine dust which can act as a dispersing agent for other contaminants.
After the coating has dried, the contractor or hobbyist should then apply primer. Primer prevents the powder coating from flaking away by providing a smooth, uniform surface. Some common primer ingredients include silicon carbide and barium oxide.
