CED Paint conductivity is dropping
A discussion started in 2006 & continuing through 2017(2006)
Q. If conductivity of CED bath is reduced up to 400 microsiemens and pH is 6.2 , then what happens in the coating? Then how can I increase conductivity?
My CED bath level is reduced daily after some processing of articles. How can we maintain bath level? (NVM % is within the limit)

A. At a pH of 6.2 you should have a paint kick-out!
Simply add the pH controller supplied by the paint supplier and your pH will fall within range and the conductivity will go up.
Your paint supplier should be able to help you on that.

Thank you Mr. Gurvin, but my pH is within the limit.Naresh Shudra [returning]

Q. Hi everybody.
I've experienced almost the same issue lately!
Although all CED bath parameters have been in the range as below, the conductivity of CED paint gradually decreased from 1600 to around 1000 value.
Moreover, we couldn't find any UF drainage or bacteria attack!
Your response would be highly appreciated :)

A. Your MEQ & pH value are not in proportion. Please check again.Avnash Vidhate
