| Step 1: Cleaning the Part | Sandblasting is the method that is typically used on hard metals. Sandblasting is done by taking fine grain abrasive materials (like sand) and firing them at a part at a really high speed. Since the particles are so fine, they aren't able to penetrate the metal, despite being fired at a high pressure. This process will remove almost all rust, dirt, and other foreign materials from the surface of a part. The result is a completely clean and smooth surface for the powder coat to adhere to. |
| Step 2: Coating the Part |
"How do you coat the part if the powder doesn't stick to anything?" In order to make the powder stick to the part, the part is given a negative electric charge. Then, the powder is fired from a gun that gives all the particles a positive electric charge. This is a perfect example of when opposites attract. Not only are the positively charged particles attracted directly to the negatively charged part, but this charge also ensures that the powder coating is perfectly distributed- right down to the molecular level! |
| Step 3: Curing the Part | The part is moved to a curing oven where the part is "baked" at 350-400 degrees. This temperature creates chemical reactions in the compounds contained in the powder. Unlike traditional paint, which dries as moisture leaves the paint, powder coating coating needs to cure because it has no moisture. That is, the powder coating particles react to the extreme heat and form strong chemical bonds with each other creating a durable shell around the part. Once this process is completed, the part no longer needs to be charged because the coating is perfectly distributed and sealed around the part. |
| Raw Materials Used in Powder Coatings | As with any coating, formulation variables are critical to the processing and performance characteristics. The powder coating formulation is much like a liquid coating formulation except that most of the components are in solid, melt-processable form. The high performance of powder coatings is further increased by the use of additives. These additives are designed to improve properties such as: Prevention of discoloration during powder coating resin synthesis and curing Ease of spraying the powder onto the substrate Enhanced durability of the coating during service life through light stabilization, and Improved corrosion resistance |
