What Is Powder Coating - STP Performance Coating

If you are Googling “What Is Powder Coating” or “How Does Powder Coating Work“, this post should help clarify. The dry finishing process of powder coating was introduced to North America back in the 1960’s, becoming very popular. Powder coating represents more than 15% of all the industrial finishing markets, as it can be used on a variety of different products. Everyday there are more companies beginning to realize that powder coatings give a durable finish of high quality, and it can improve inefficiencies, it is environmental compliant, while at the same time allows for maximized production.

Powder coating is used for functional purposes, which is protective, and it is also used for decorative finishes. Powder coating can be purchased in an unlimited spectrum of colors, and a wide variety of textures. The advancements in technology has given powder coating very good performance properties.

How Does Powder Coating Work?

How Does Powder Coating WorkPowder coatings are a combination of polymer resin systems, curatives, leveling agents, pigments, flow modifiers, and several other additives. The ingredients are mixed as they are melted together, then the mixture is cooled down and grounded into a powder, kind of like the flour we use in cooking. Electrostatic spray deposition (ESD) is the process that is generally used in order to achieve a metal substrate in the powder coating or the application of it. This application method consists of using a spray gun that applies an electrostatic charge to the particles of the powder so the will attract the grounded parts.

Once the powder coating receives this application, all of the parts are then placed into a curing oven. The heat from the oven makes the powder coating have a chemical reaction, producing long molecular chains, which will not breakdown easily, causing it to result in high cross-link density.  This is the most commonly used method for these types of applications for applying powders. Powder coatings are also applied to medium density fiberboard (MDF) and plastics, which are non-metallic substrates.

There are times when a powder coating will be applied while it is in the process of a fluidized bed application. This is done by dipping parts that are preheated into a hopper filled with fluidizing powder and the coating melts (made earlier from combining the ingredients given above). It depends on the type of powder used, the mass, and the temperature of the parts, as to whether or not a post cure will be needed. Regardless of the application process used, using the powder coatings will be easy, cost effective, environmentally friendly, and very tough.

Powder Coating Durability

Powder coating has a high quality finish and is used on thousands of different products that people come into contact with on a daily basis. Even rough and tough machinery get protection from powder coatings, as does various household items people depend upon daily. Powder coatings have more of a durable finish compared to liquid paints, and it also provides an attractive finish.

Products that have been powder coated have more resistance and the quality of the coating will not diminish from impacts, chemicals, moisture, ultraviolet lights, or from extreme weather. Which means that it is going to reduce the wear and tear on the products, decreasing risks of being scratched, chipped, accumulation of corrosion or abrasions, among other issues of wear.

Powder coating is tough, looks terrific, very durable, has its environmental advantages, and it is going to last for a very long time. Learn more about powder coating vs painting by reading this blog post.

What Is Powder Coating?

Powder coating is an improved and newer type of metal painting and finishing process that has completely replaced liquid painting when there is a need for durable paint. For instance, your car rims will have a lot of wear and tear, and often will need to have a strong coating than something that can’t handle a lot of damage.

Powder coatings are applied as a dry powder and the difference between this and liquid paint is that the powder coating doesn’t need any solvents to keep the filler and binder parts in a liquid form. The powder is applied electrostatically and then cured in high heat to cover it.

The powder coating will be thermoset polymer or thermoplastic. It is normally used to make a hard finish that is harder than your average paint. Powder coating is normally used to coat metals which is best for custom cars.

The Powder Coating Process

Powder coating a motorcycle, car or truck part does require the item to be pre-treated before it is ever coated. The pre-treatment is made from a mix of abrasive mechanical cleaning and chemical cleaning to prepare the surface for coating. Powder coating will turn out best whenever the coating or rust has been removed.

What is able or not able to be powder coated?

Powder coating is done best whenever it is applied to metal parts, weldments, and assemblies. Things that are not metallic such as glass, wood, plastic, fabric, ceramic, and rubber can’t be powder coated. Soldered items cannot be coated because of the high temperatures needed for curing.

Before Coating

Before powder coating, all items are hung on a rack. This allows them to be coating completely. The application is done in a clean boot that will keep other powder colors and dust out. The parts are then electrically grounded and then the powder is applied using a sprayer that electrically charges the powder. Once the powder is charged, it attracts the grounded item.

After Coating

Once the item is coated, it will be removed from the rack it is placed in a curing oven. Once the part is heated, the powder becomes a gel and flows over the item evenly to create a smooth finish. Once the powder has reached the curing temperature, cross linking happens. Once it is finished, the parts are placed in a place to cool and then used.

Powder coating won’t always work for every situation. For instance, if you are trying to match a certain color it will not work.
