Electrostatic Spray Painting

What Is It and How Does It Work?

What Is Electrostatic Spray Painting?

Electrostatic spray painting is a method of spray painting that uses electrostatic spray. Electrostatic spray is the spray application process in which the coating and part to be coated are oppositely charged.

How Does It Work?

Spray paint leaves the nozzle of the sprayer, through an electrostatic field at a fast pace (so they can draw the electrostatic charge out of the field with them) and is given a charge. The object the spray is sticking has to be either grounded or the opposite charge of the spray. This causes the particles in the paint to be attracted to the object being painted.

Why it is More Effective than Regular Painting.

The paint droplets spread out more as they leave the gun. This is because they all have the the same charge so they repel each other. This is better than coming straight out of the gun because the paint will cover a wider area. The paint droplets are also attracted to the metal that is grounded or has an opposite charge, so less paint will be wasted by landing on floors or walls.

What Can Be Painted Using Electrostatic Spray Painting?

Anything metal from elevator doors, cabinets, handrails and equipment such as dental, hospital and x ray equipment.
