Aluminum, bronze, copper, brass, titanium, and steel (including stainless, galvanized, anodized and e-coat) can all be powder coated. If the metal can hold an electromagnetic charge and withstand the heat from the curing process, it can be powder coated.
WHAT IS POWDER COATING
Powder coating is the process of applying a dry coating to a surface as an alternative to using a liquid medium (such as paint or a solvent). The powder is made-up of several different components that are mixed together and processed into a solid mass which is then broken down and granulated into a powder that’s finer than salt.
HOW DOES IT WORK
This granular form allows the powder to be evenly applied to a surface in a consistent manner. The dry powder is electrostatically charged and sprayed onto the surface needing coated. Once the powder has been thoroughly applied, the newly-coated part is placed into a curing oven. This is where the powder melts and adheres to the part, creating a smooth, hard coating.
WHAT ARE THE ADVANTAGES
Powder coating has several advantages over liquid finishes. Generally, powder materials are less expensive and less labor-intensive to produce, which makes it a more affordable choice. The quality of finish that’s offered is very durable and provides exceptional resistance to heat, chemicals, extreme weather, and corrosion, in addition to a consistent finish that doesn’t drip or run. Powder coating is also very environmentally friendly - compounds aren’t evaporated into the atmosphere because the airborne powder is easily filtered and has low health risks for employees.
ARE THERE LIMITATIONS
In order to properly powder coat a surface, it must first be clean. This means you cannot powder coat over an existing finish, including any chrome finishes. However, PowderTech utilizes a 6-stage cleaning system which includes a low-concentration acid wash, neutralizing rinse and alkaline cleaner to ensure that your product is completely clean before being coated.
