What is electrostatic spray paint?
Electrostatic spraying is a coating method that uses a spray gun to positively charge electric particles while the workpiece is grounded, or negatively charged. The process delivers high transfer efficiency, reduces costs, and can improve environmental performance.
Can you spray paint with an electrostatic sprayer?
The spray paint gun is charged positively, which causes every paint particle to become positively charged. Since the paint particles all have the same charge, they repel each other and produce a fine mist of paint which is sprayed towards the car.
How does static electricity spray paint work?
ELECTROSTATIC PAINT SPRAYERS FOR LOW TO HIGH VISCOSITY It is used for the application of low- to medium-viscosity fluids for products requiring a high-quality, class A or decorative finish.
Where are electrostatic paint sprayers used?
ELECTROSTATIC PAINT SPRAYERS FOR LOW TO HIGH VISCOSITY It is used for the application of low- to medium-viscosity fluids for products requiring a high-quality, class A or decorative finish.
What is the meaning of electrostatic paint?
An electrostatic paint is a type of spray coating that is used to efficiently coat a metal substrate by inducing an electrical charge to the paint particles that make up the spray, causing the paint to adhere to the metals oppositely charged surface.
What are the disadvantages of electrostatic painting?
What are the downsides of electrostatic spray painting?
- Cost of Buying New Equipment. The cost of electrostatic coating equipment is higher than standard application equipment, but it can be quickly absorbed by lower labor and materials cost.
- The Faraday Cage Effect.
- Retraining Employees.
Do you need special paint for electrostatic painting?
There are a few paints tailored for electrostatic use, though a special type is not required. Almost any oil-based variety without metallics and thinned with specific chemicals work well for most applications. Water-based types usually dont work for this process without special precautions and setup.
Can I use electrostatic sprayer for paint?
Spraying with electrostatic spray guns provides an excellent finish quality. Electrostatic paint guns also deliver a very high transfer efficiency of up to 90%, resulting in cost savings for paint, a reduction of VOC (volatile organic compounds) emissions, less cleanup and faster production.

How does static electricity enable a car to be spray painted?
A smooth paint finish on the surface of a car can be achieved by using static electricity. The paint particles all have the same charge, so they repel each other and produce a fine mist of paint that is sprayed on the car when they are all sprayed together
How does a electric spray work?
The motor drives a piston inside the sprayer at up to 7200 pulses per minute, creating suction that pulls paint up through the draw tube. 4. The paint travels past the piston to the atomizer valve, which moves in a swirl pattern to break up the paint for spraying.
Where is electrostatic painting used?
Electrostatic painting is a very efficient, cost-effective and clean method of painting. It can be used on conductive surfaces and provides a smooth finish. It produces a strong and durable coating that will endure for years to come. This process has been used in factories for many years.
What are the uses of electrostatic spray painting?
Cost savings
- Paint wastage.
- Clean-up and associated cleaning product and labour costs.
- Spending on the disposal of hazardous waste.
Where is electrostatic paint used?
This process, used extensively in the automotive industry, can also work for your home or business. Its already used in commercial applications on things like metal fencing, railings, doors and windows. These large objects prove difficult to ship to a powder coating shop.
What are the benefits of electrostatic painting?
Because electrostatic painting ensures a transfer rate of 98% of paint products to metal surfaces, it causes limited to no overspray. This efficiency means there are fewer volatile organic compounds (VOCs) released into the air.
Is electrostatic paint more durable?
The electrostatic charge between the negatively-charged paint particles and the positively-charged surface of your product creates ionic bonds between the two materials. Ionic bonds are one of the strongest chemical bonds, making electrostatic spray painting one of the most durable industrial finishing techniques
