Voltage required to apply e-coat that is used on automobiles
I am trying to set up a small one gallon e-coat bath where I will be doing some compatibility testing with e-coat and various lubricants. I need to know about how much voltage and amperage is used in the e-coat process. The reason I need to know is so I can spec out the proper power supply to do the job. I realize that the power requirements will vary from various e-coat suppliers so I was just looking for a general range.
It will be far simpler to request the E-coat paint company to supply you precoated panels for your tests!
Nonetheless, voltage required is a function of the chemistry and the E-coat paint company will provide you the data when you buy the E-coat paint. For epoxy we use 200 volts for 20 microns at 32 degrees C for PPG chemistry.
Current for the chemistry we use is approximately 2 amperes per square foot per minute.
But for both these figures depend upon the E-coat paint supplier for correctness of the information.
