Electrostatic Spray Painting Basics
If you’ve ever tried to spray paint a metal object, you know how difficult that can be. Uneven coverage and overspray can make the items look like preschool art projects. Fortunately, you can avoid those problems with electrostatic spray painting. This is the preferred method for painting metal objects, but most people don’t understand what it is or how it works. Get the basics so you will know if this method is a good option for you and Spray Finishes do the work!
An electrostatic spray-painting machine can emit liquid or powdered paint. In both cases, the paint is electrostatically charged, but that can happen in one of two ways. First, the sprayer can apply a charge when the paint is still in the reservoir. The other option is to add a charge to the barrel of the gun. Then, when the paint moves through the gun, it gains a charge from static electricity.
Regardless of which charging option used, all the paint will have the same charge when it comes out, and the metal object will have the opposite charge. Opposites attract and particles with the same charge repel, so this works perfectly for painting. The paint droplets repel the other droplets, so all of the paint distributes evenly. At the same time, the paint and the metal are attracted to one another, so the paint fills up crevices and distributes across the entire object. When you see this in action, you will likely think of two magnets with opposite charges coming together. The attraction is that powerful.
Advantages of Electrostatic Spray Painting
Electrostatic spray painting has several advantages that you should consider. First and foremost, it forms a powerful bond between the paint and the metal. That means that once the paint is in place, it will stay there.
It also does a great job of covering three-dimensional objects. It has good wraparound and edge coverage, and the particles of paint will change direction midair to reach all the edges and crevices. This makes it very easy to spruce up metal objects and make them look like new.
In addition, it creates a uniformed look. The paint has the same thickness all over the object, so it will look as if it just came out of a factory.
It’s also fast drying. It dries to the touch in around an hour, and it can be used the next day, although light use is recommended at first. It won’t be long before it is ready to go through the paces, though.
Also, the process is quick, so there will be minimal interruption to your business. Professional painters plan the job ahead of time and then get in and out quickly so you don’t have to worry about a thing.
It also comes in a large variety of color options. Try moving past the standard blacks and grays, and go with something bold!
Finally, it can be done in-house or in a factory. You can have someone come in and spray paint your filing cabinets, elevator doors, and other metal objects without taking them out of your building. Also, large metal objects don’t have to be taken apart. This makes electrostatic spray painting the obvious choice for lots of businesses.
Disadvantages of Electromagnetic Spray Painting
Just like any other project, there are some disadvantages, as well, although they are minor. This process only works with conductive materials. If the material isn’t conductive, however, there are ways you can use bonding to make it conductive.
You must also be careful with the equipment. The equipment tends to be delicate, and if you use it improperly, you could potentially start a fire. Of course, you don’t have to worry about that if you go with a professional company, like Spray Finishes.
