Materials you can Powder Coat



Powder coating can be used to coat many types of materials. The most common material is metal, but you can also powder coat wood, plastic, composites, glass, and MDF. The first consideration for coating objects besides metal, is can it withstand the temperature. Most plastics will melt when subjected to 400 degree heat for any length of time so it is important to research exactly what your object is made of before you try to powder coat it.

Powders



Powder is one of the most difficult parts of the whole process, choosing one that is. There are literally thousands of different kinds of powders in different colors, textures, and gloss levels. Then add in the fact that you can mix powders(Beginners, don't do this yet!) and do multiple coatings to achieve even more looks. It is baffling, I spend a huge amount of time selecting colors.  If you would like to know some reputable websites to purchase powder from, check out my recommendations.

Powder Coating Ovens

In order to powder coat, you will need some type of oven in order to cure the powder coating.   You will need an oven that is capable of sustaining 450 degrees and it will have to be large enough to fit your powder coated objects inside of.  There are several different options available to a beginning powder coater and they will be discussed in this post. 

The cheapest powder coating ovens that you can use to start with if you don't want to spend too much money are: a toaster oven, a household oven, or a propane grill. You can also get lucky and find a cheap commercial oven.  If you have a larger budget, you can build or buy a large dedicated powder coating oven.  Powders coating ovens are one of those things where the price goes up gradually with the size until you pass household oven and then the price jumps into the thousands of dollars range. An oven you could fit 4 wheels or a bike frame would cost you $2000 or more. If you want to an oven that will fit a car, you're looking at $10,000 to $20,000.  






What is Powder Coating?



First I will cover the very basics of what powder coating is.

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.
