Electrostatic Application of Industrial Paints

Electrostatic Spray

- Air Assisted Electrostatic Spray

 

 

 

Electroststic Spray uses conventional or HVLP atomization combined with an electric charge to attract paint droplet to a grounded surface.  Air Assisted Airless spray uses a both hydraulic and pnuematic pressure to atomize, combined with an electric charge to attract paint droplet to a grounded surface.

The Electrostatic methods combine high productivity and transfer efficiency with a high quality finish.

 

Potential Attraction

The process combines aspects of HVLP and conventional methods with charged particles.  Spray particles receive initial velocity from atomization.  A negatively charged (grounded) substrate provides wrap and excellent edge coverage.  The method has a 75-85% transfer efficiency and produces very little bounceback or overspray waste.  

Safety concerns include electrical shock and ignition hazards.

Electrostaic spray provides a medium production volume close to Air Assisted and higher than HVLP.  The main benefits are oaint savings and lower waste.  Electroststic spray is a growing technology in industrial finishing, but requires a high initial equipment investment.  Equipment is customized for each paint chemistry.
