What is Powder Coating?

Powder coating is the process of applying a paint in the form of powder. Regular liquid type paints are pigments and binders suspended in solvents. Powder coating is solvent free so you are just using the dry pigments and binders. Once the powder is sprayed on your work piece, it must be baked from 350 to 400 degrees F for 10-20 minutes.  Each powder has its own specific curing schedule and you should always that schedule when dealing with that particular powder. When the powder is heated, it melts into a liquid, connects together, cures, and once cooled, is dried to a hard, beautiful finish.



You can powder coat almost any object that can withstand the cure temperature of the powder. It is the most common to powder coat metal, however, you can also powder coat composites, MDF, glass, and other items that will not be damaged when subjected to powder coating temperatures. 

Generally, when powder coating metal, the powder is given a positive charge when it leaves the gun and it is attracted to a grounded workpiece. Once the piece is fully and evenly coated, you carefully transfer it to an oven that can heat the powder to the specified temperature. The powder will melt, flow out, and then cure during this process. The usual specification for the piece is anywhere from 350 degrees F for 20 minutes to 400 degrees F for 10 minutes.

Powder Coating metal serves a couple of purposes.  The functional purpose is that it provides a barrier between the metal and the oxygen around it protecting it from corrosion.  When it comes to iron or steel, this is very important to prevent rust. . However, if the powder coating is scratched, or chipped down to the bare metal underneath, rust can start in this spot.  Media blasting a part before powder coating will provide a profile for the powder to adhere tightly to the part, this helps reduce the spread of rust underneath the powder coating after it is scratched and keeps it centralized to just the scratched area.  You can read more on creating a profile here.

The aesthetic purpose of powder coat is that you can choose from an almost unlimited amount of colors, textures, gloss-levels, ect. Powder coat colors can be applied in multiple coats to achieve even more unique finishes.

My name is Sean and here I will discuss in detail how to powder coat. If you have no idea what powder coating is, I first suggest reading "What is Powder Coating".  The main focus of this guide is DIY powder coating but there will be plenty of information here for anyone that powder coats.

Being able to powder coat means being able to apply beautiful durable finishes using relatively low cost equipment, and the basics can be learned quickly. The best part about powder coating is that you don't need a large elaborate collection of equipment to do it yourself. The equipment definitely helps and improves the time spent and the final product, but how involved and how much money you want to spend on equipment is up to you.  Powder coating is a great hobby and if you are willing to put in the time to learn it properly and invest in the right equipment, it can be a great career as well.
