Find out more about powder coating.
Powder coating is a finishing method also
known as dry painting. Introduced in North America over 40 years ago, it represents over 15% of the industrial finishing market and is used for many different products. Companies are increasingly requesting powder coatings to ensure a high quality and durable finish, maximized production, greater efficiency, and effortless environmental compliance. Anderson Powder Coating Plus offers coatings in an endless array of colors and textures as well as some unique performance properties.
How does the powder coating process work?
Powder coatings are polymer resin systems mixed with additives, such as curatives, pigments, leveling agents, and flow modifiers. To create the powder, these additives are melt mixed, cooled, and grounded to give the powder a consistency similar to baking flour.
During electrostatic spray deposition or ESD, a spray gun is used to apply an electrostatic charge to the powder to ensure it sticks when sprayed on the metal. After the powder is applied to the product, the product is baked in an oven and the coating reacts with the heat, producing long molecular chains that are very difficult to break.
While this is the most common powder coating application method, a fluidized bed application can also be used, which involves dipping pre-heated metal into fluidized
powder and allowing the coating to melt and cover the product. This method may require post cure depending on the size and temperature of the product and the type of powder.
Because it has a high quality, long-lasting finish with an attractive look, is environmentally advantageous, and more durable than liquid paint, you'll find powder coating on thousands of products, from industrial machinery to household items you use on a daily basis. Due to the durability of the finish, powder coatings aren't affected by impact, moisture, chemicals, UV light, or any other extreme weather, which reduces the risk of wear issues like scratching, chipping, abrasions, corrosion, and fading.
What is powder coating?
Powder coating is a finishing process that involves applying tiny dry particles to the product. Also known as dry painting, the powder coating process is clean and efficient relying on the attraction of charged particles that are fused together. After the coating is applied, your product is placed in the oven to bake. This allows the powder coating to melt around your product and cover the metal in a plastic sheet.
Unlike wet spray painting, powder coating generally includes:
- Less mistakes
- No harmful chemicals
- Quick drying time
Once your product has cooled down, it's ready for recoating
, handling, or packing.
How does the powder stick to the metal?
To help the powder coating stick, the team at Anderson Powder Coating Plus first cleans your product of any old finishes as well as dirt, oils, and other contaminants. A special wash process also micro-etches your product's surface to ensure the powder sticks better. Finally, an electrostatic process is used to charge the powder while your product is attached to a ground wire allowing the coating to stick to the metal while it is baked in our oven.
What does baking mean?
The baking process is an important step after coating your product with powder. The heat from the baking process melts the powder and creates a plastic sheet around your product. The powder bonds to itself as well as to your
part giving it more durability and a professional finish. If not baked properly, the powder won't bond properly, which causes the powder to be weaker and be more susceptible to chipping.
What are the different types of powder and how durable are they?
There are many different types of powder, so it is important to consider the item you're coating
before deciding on the powder that's right for you. For example, outdoor finishes are designed to hold up in all weather conditions, including rain, snow, heat, cold, and UV rays. They are also rust-inhibiting to protect the look and feel of the product making outdoor powders great for outdoor equipment and vehicles.
Indoor powders are slightly different protecting against chips, scratches, and everyday wear and tear instead of the elements. They are highly customizable with special mixtures that combine maximum durability with a texturized
Whether an indoor or outdoor powder is best for your product, you can rest assured all types of powder coatings are extremely strong and durable with the ability to withstand the harshest conditions and still maintain its picture-perfect look.
What colors are available?
Powders are available in just about every color, but it's important to remember that not all brands are created equal. If you have a particular color in mind, let us know so that our team can match it as closely as possible without sacrificing the quality of the powder. You'll usually be able to choose from several powder options.
some colors cost more or less than others?
Yes, because the price of a particular color of powder depends on several factors, including the availability, ingredients, and supplier. Stock colors will generally cost less than harder-to-find colors that have to be special ordered. Other powders have unique properties that make them more expensive, such as textures, candies, metallics, and glow-in-the-dark products. The cost of the powder is only one factor, however. Setup labor and item processing also factor into the total cost of your powder coating service.
Can powders have textures?
Yes. Because the process lets us create different surfaces and wrinkles without any extra work, an ever-increasing selection of textures is
available at no additional cost. You can even add veins and hammertones, which are streaks of different colors that appear throughout your product to add dimension.
Can powder coating be used on
No. Because the product must be baked at temperatures of more than 400 degrees, there are many materials that wouldn't survive, such as wood, plastic, and rubber. It is recommended that the product being powder coated be constructed of some sort of metal or something that can survive the high temperature of the oven. The size of your product should also be taken into account as our oven is 8'x8'x20' and any product you want to powder coat needs to be within these dimensions to fit in the oven.
Why is powder coating better than wet spray painting?
It is generally more cost effective to have your product powder coated once than to paint it numerous times during its lifespan. Some other reasons to choose powder coating over wet spray painting include:
- Powder coated products are cured as soon as they cool down cutting down the time of the process
- Thermal bonding process creates a more durable finish
- No harmful chemicals allow for a more eco-friendly product
- Air gun used to blow away misapplied powder and eliminate mistakes easier
- Available in numerous colors and textures and can be baked to create veins of different colors
- More durable and weather-resistant
Can my product still be powder coated if it was previously treated?
Yes. Our team will remove old finishes as well as dirt, rust, or anything else on the surface to prepare it for powder coating.
Can my product still be powder coated if it was previously wet spray painted?
Yes. No matter what type of finish was on the original product, our team will remove it and get your product down to the bare metal before powder coating it.
Can a single product have multiple colors?
Yes. For an additional setup charge, our team will simply powder coat one color at a time and mask off
the places that are different colors. If your product can be broken down into smaller pieces, powdering it with several different colors would be much easier and the overall quality would be much more consistent.
Can some areas of my product be bare?
Yes. Our team can mask off areas that aren't being powdered and place rubber caps over or inside threaded holes and extensions to prevent the powder from sticking to that section.
Can you do small custom jobs?
Yes. Whether your job is small or large, you can rest assured our team will handle it with care, and a high level of service is provided to all our customers. We do not charge extra for the size of a job, but it is recommended that you try to keep your whole product the same color to save time and money.
Can you do large jobs?
Yes. Our oven has large racks that allow us to take on both large quantity jobs and large product jobs and get them done faster and more efficiently.
