What are the benefits of using powder coating gun?
Powder coating involves the use of a powder consisting of fine pigment particles and resin. These are charged with an electric current then electrostatically sprayed onto a grounded surface.
This process results in a uniform, attractive finish that lasts longer than an ordinary paint job.
Compared to other finishes, the powder coated surface is better at holding up to fading, chipping, and wear in general.
Another benefit is that of limitless colors and finishes, including candies, glitter, wrinkle, iridescent, matte, high-gloss, and a lot more.
The colors remain vibrant for longer than what a liquid paint job offers.
When it comes to protecting the environment, powder coating is preferred to ordinary painting.
Liquid paints usually have solvents containing VOCs, which pollute the environment. Powder coatings, on the other hand, have no solvents, and they release insignificant amounts of VOCs into the atmosphere.
So, powder coating is:

1. Chicago Tools Powder Coating System (10 to 30 PSI)
- A perfect powder coating gun for vehicles at home or the shop
- Uses any standard powder coating paint
- Includes powder coating gun, foot switch, power source, inline filter and two powder cups
- Requires 10-30 PSI air pressure
If you’re looking to create a nice and smooth finish, you need a powder coating gun that is high-grade and able to handle your workload.
Furthermore, it should be robust and the maintenance it needs ought to be minimal.
Going by those terms, the Chicago Tools Powder Coating Gun is a performer. It’s a hopper-fed gun that comes with all the items you need to get started.
That includes a power supply, a foot switch, an inline filter, and 2 hoppers for holding the powder.
This gun shoots any type of powder, including metallic, texture, and chrome, making it a versatile tool for the hobbyist or the small shop owner.
Rather than using one hand to operate the gun and the other hand to work the switch, you’re able to use one of your feet to work the switch. This makes using the tool easy and convenient.
One of the nicest features of this model is its smooth and accurate air flow. With a simple turn of the valve at the base of the handle, you’re able to fine tune the air flow to suit your needs.
As mentioned, the package comes with an inline filter. This is a small feature attached near the base that filters out the moisture and ensures the air getting through to the nozzle is totally dry. This helps ensure the work is clean and effective.
There are two major shortcomings of this. Firstly, it’s difficult to clean when switching the colors.
Secondly, the heat-shrink tubing over the wires on the handle isn’t that good. You might want to cover them with tape.
All things considered, this gun is a great pick. It’s a performer, and it seems robust too. Going for around 100 bucks, it’s a good buy.

A really nice fact is that you never have to deal with the hand switches, foot pedals or box controllers. All these controls are built right into the gun. Pretty convenient.
Want to be able to reach long distances between the power and air supply and the tools you’re powder coating? You’ll love the extra long 10-foot cord and cable that come with this gun.
Versatility is yet another benefit you’re going to enjoy with this gun. It works on glass, plastic, wood, and metal, for both coating and recoating applications.
Cleaning the gun is super easy too, thereby making switching the color a simple process. All it takes is a quick blast of air.
The shortcoming with this gun is the airline in the handle. It’s sort of weak, so you might want to handle it carefully.
Other than that, the gun is really cool and well worth the money.

Currently going for 398 dollars, this item is unbelievably low-priced considering the amazing industrial usability it offers.
First off, the powder hopper is made of stainless steel, making it pretty robust. It has a capacity of 45 liters, which is equivalent to around 12 gallons.
That’s lots of space for putting your powder paint. It lets you work on many or huge workpieces without having to refill too frequently. Very convenient for the professional.

When you open the package, you find everything you need to get started immediately. That includes a powder gun, a power supply, power and ground cables, and more.
The power supply is adjustable. It can go from 0 to 100 kV, meaning you can do both the flat panels and the recessed parts like the corners without a problem.
With the quick adjustment knob on the box, setting the right kV is a breeze.
This model features an adjustable air supply knob. This part lets you set the rate of air output based on your needs. Whether you want a slow stream of powder or a fast flow, it’s easy to achieve it with a simple turn of the knob.
On the power supply, there’s a pressure gauge. With this, you don’t have to guess the air pressure; you have the accurate figures. Hence you can effectively increase or decrease the air pressure.
The design of the gun is pretty cool.
It’s a lightweight item, so you don’t get exhausted using it.
The coolest part is that the nozzles and tips are removable. You get two different nozzles – one for flat spray and another for multicoat application. You also get two tips of different sizes, including a wide mouth one for the difficult surfaces.
All you need to do is connect the right nozzle and tip for the job at hand.
With the quick release on the powder hose, changing colors is easy and quick.
Well, here’s the main drawback – the current price of 812 dollars.
That’s too high compared to other models like the RedLine EZ50, or the Chicago Tools Powder Coating System, which offer similar features at less than half the cost.
5. Powder Coating Gun with Bonus Powder Cup Kit, Next Generation U.S. Power Supply and U.S. Airline Adapter

Are you in the US? Allow us to show you why this could be the perfect kit for you.
If you liked the EZ50 RedLine model we discussed above, you would love the full kit even more. The gun that comes with this kit is the same gun we talked about earlier.
The only difference is that this is a full kit, so you get other useful items besides the gun. If you’re looking to get started immediately you open the package, then you will find the extra items very helpful.
So, let’s go ahead and see the features, the benefits, and any shortcomings.
As we’ve stated, the gun is the same EZ50 model we talked about earlier. If you observed the features and benefits well, then you know this is the perfect powder coating gun.
First, there are no box controls, as everything is built right into the gun. You no longer have to deal with foot pedals or hand switches. You control everything from the gun, and this is immensely convenient.
There’s automatic powder control that is built into the gun. That ensures there are never sudden surges or those annoying powder clumps.
On the gun, there’s a knob for controlling the powder output. By adjusting the knob, you get to set the powder flow to the rate that you want.
Most models provide you with power cords. But, in most cases, the cord is only up to 5 feet long. Well, guess what? With the EZ50 from RedLine, you get power cables that are 10 feet long.
That’s freedom right there allowing you to reach much farther than you would using other brands.
Now, this package includes 3 extra powder cups as well as extra tips and nozzles.
And most importantly, you get the power and airline adapters compatible with USA power and air systems. This is a huge benefit if you’re in the US.
6. Kool Koat 3.0 DPW Electrostatic Powder Coating System
- SIGNATURE REQUIRED FOR DELIVERY
- Adjustable KV's (0-100) with Digital Pulse Wave technology
- Switchable Display from KV to AMPS
- Integrated gauge powder feed adjustment
- Secondary Air Feed adjustments for optional accessories like industrial hoppers, etc
Want to avoid the faraday cage effect?
For those of you who are still new to powder coating, the faraday cage effect is what happens when coating the inside of a box-like item and the powder sticks to the side but not the corners.
The Kool Koat 3.0 DPW has a little red button on the front for engaging the DPW mode. What the heck is that?
Well, DPW represents digital pulsation wave. When the button is engaged, the system is able to combat the faraday cage quite beautifully.
It helps get the powders to crevices and corners.
Holding the gun feels comfortable. The handle is just the right size for the standard human hand, and as the gun is lightweight, you don’t get fatigued using it.
One of the nicest things about this gun is that it comes with removable tips. You can connect the suitable tip for the current application.
Three tip varieties come with this model. There’s the conical, fan, and wide mouth tip.
For those huge flat surfaces and the difficult ones, the wide mouth tip is incredibly helpful. It spurts out huge amounts of powder, enabling you to complete the task quickly.
But, you want to be careful while using it as it can be a bit wasteful.
The digital readout for the voltage and the amperage is also nice. However, you can only display one of them at a time; not both.
The other drawback is that there are only two air supplies.
If you’re using a fluidization chamber, you really need three.
Beyond those issues, this is a fine powder coating system. It produces a smooth and thick finish.
At the price range (1278 bucks at the time of writing this review), it’s on the high side, but for the professional, it will work. Definitely better than most of those budget models.

You got to check out the MXBAOHENG Powder Coating System.
Unboxing the package, you will find a powder coating gun, a power supply, a foot switch, a 15AWG power cord, a hopper, an inline filter, and a couple more items.
With so much stuff, you get to start powder coating immediately.
This system needs 110 volts to work, meaning you can hook it to your home wall outlet and operate it without having to get additional electrical components.
There’s also a 220-volt model in case that’s what you prefer.
A vast majority of models out there come with a hand switch that you have to use to activate the gun. This model, on the other hand, has a foot switch.
Rather than using one hand to hold the gun and the other hand to operate the switch, you use your feet to operate the switch. That leaves you with both hands to work the gun, and it feels very convenient.
When shopping for a powder coating system, you want to know the feel of the gun. Why? Because comfort is important.
One cool thing about this system is that the gun is lightweight. You certainly won’t feel exhausted using it. Secondly, it has a nice, non-slip surface that makes operation a cinch.
The only issue we have with this model is the long shipping time. You might have to wait more than 2 weeks to get your package, and that isn’t nice for most people.
On the brighter side, this system will do the job if used for small scale applications.
Top Quality Powder Coating Gun Reviews and (In-depth Buying Guide)
When it comes to powder coating, the spray gun happens to be the vital element. If the gun is faulty, you’re not going to have a beautiful, smooth, and even finish. But with a good one, you’ll enjoy all these benefits.
To choose a powder coating gun that works well, consider the following factors.
The kV represents the output voltage of the gun. In other words, it determines the amount of voltage that charges the particles of the powder coming out through the nozzle.
The gun should have an adjustment feature that helps you set the kV to the convenient level. At higher levels, the particles become greatly charged, and they easily adhere to the grounded surface.
And at lower levels, the particles are not very charged, and that allows them to travel further to reach those recessed areas.
So, it’s important to be able to set both high and low kV levels.
If you’re a mid range powder coating gun for home use, one with kV levels between 0 and 50 kV will do just fine.
But if you need a professional powder coating gun, then you got to get one whose kV you can increase to at least 100 kV.
The spray efficiency will determine the rate at which you can complete the task.
If this factor is important to you, then you need a gun that has a knob for increasing and decreasing the airflow. By tweaking the airflow, you’ll be able to shoot the powder at the rate you prefer.
Some guns also come with built-in powder flow control features, and these are quite helpful.
Nozzles and tips
The size and shape of the nozzle and tip will affect not only the spray rate but also the manner in which the powder comes out.
For instance, a smaller, thinner nozzle will release thin streams while a bigger nozzle will release clouds and lots of it at a time.
Though a premium feature, it helps to have a gun with replaceable tips and nozzles so you can use the ideal ones for each project.
Ease of cleaning
When changing between powder colors, you normally have to clean the gun. The same case applies after the project is complete and you want to store the equipment.
Look for a gun that you can clean easily by blowing over it air from your compressor.
If you’re looking to travel with your powder coating system from time to time, then you need a portable model. That means something lightweight and of compact size.
The RedLine EZ50 doesn’t come with a power supply box; all the electronics are built into the gun.
This makes it extremely convenient to transport. Moreover, it comes with a 10-foot power cable (almost twice as long as other models), meaning you get to reach farther when working.
When thinking about the portability, you want to also consider the size of the hopper. The 1 to 3-pound hoppers are much better in this regard than the large-size tanks with capacities ranging over 10 gallons.
Powder Coating Machine Types
Powder coating machines two basic types. Each types has upsides and downsides of each: Corona & Tribo. The way of transporting the powder from the gun to the part is the main difference.
Corna Style Spray Guns
This is the mostly used type. Reduced wear rate and low air consumpion are two great advantage of corona styl gun. Compatibility with the widest variety of powder is also a great advantage of this type.
Tribo Style Coating Guns
Tribo coating gun is less used compared to corona type. This type has the ability to coat in recessed corners and similar challenges. But tribo gun is slower than corona syle gun.

Frequently Asked Questions
Q. What is the difference between a powder coating and a regular liquid paint?
The difference is that paint uses solvent while powder coating doesn’t require it. A powder coating normally needs heat setting while a regular liquid painting doesn’t.
Q. Is powder coating harmful to health?
One of the reasons as to why powder coating is preferred over regular wet painting is that it is totally safe. As it doesn’t contain solvents, it’s non-volatile, and it releases no harmful chemicals into the atmosphere, before or after application.
Unlike some wet paint, a powder coating is not flammable, and hence it doesn’t pose a fire hazard.
Q. Gun not showing KV reading, what's the issue?
power loss of the whole unit, circuit board failure or cascade failure can cause this problem. These are not any major problems and can be solved by electrical techinician.
Q. Corona or Tribo - Which is ideal?
Tribo guns have a lower charging rate for any powder. On the contrary, Corona guns are more versatile and can be used to charge any chemistry of particles.
Q. Can I powder coat over a painted surface?
The paint will prevent the powder coating from adhering to the surface. Hence, you want to scrape it all first before application.
Q. How do you prepare a surface for powder coating?
Firstly, remove any paint or rust that may be on the surface you’re powder coating. You can use sandblasting or chemical removers.
Next, clean the surface and if you use a liquid, let it dry. Then, apply the spray.
Q. Can I touch up a powder coated surface?
If you can see flaking or other signs of deterioration on a small part of the surface, a touch up with a powder coating isn’t always the best idea. Why? A visible line might be left at the edges of the new coat.
If you can’t sandblast the item and apply fresh powder coating, then try touch up with liquid paint.
Q. What are some of the benefits of powder coating over painting?
First of all, a powder coating will last much longer than a liquid painting. Secondly, powder coating, unlike liquid painting doesn’t pollute the environment with VOCs.
Q. Can I use a heat gun to cure a powder coat?
Yes, but you’ll land into problems. You see, a heat gun won’t provide the stable, uniform temperature that’s needed for proper curing. An oven, on the other hand, provides the needed heating conditions, and it’s, therefore, the perfect option for curing.
Q. What can I powder coat?
You can powder coat any metallic item capable of holding an electrostatic charge, and that can withstand the high temperatures needed for curing.
Metals are the best material to powder coat. Household appliances, vehicle, and bike parts, and guns are just some of the common items that people like to powder coat.
We’ve reached the end of our post, and we hope that by now, you have made up your mind on what model to secure.
