A. I have never seen any data to backup any claim that clear is more conductive than yellow chromates. Because you can achieve a clear from a yellow chromate simply by bleaching the yellow color from the part after chromate.

So I would say no that there is no substantial, measured difference in the two. Now if the chromate is a true clear, than the possibility might exist, but again I have my doubts. Best bet is to contact the supplier of the chromate and ask them directly. They should know, and if they don't know, then assume what I said, that the answer is no.

A. In general terms, the lighter the chromate, the less the resistance (greater the conductance). A note of caution, however, there are two ways to get a clear chromate: using a true clear as deposited chromate and depositing a yellow / gold chromate and leaching it out with hot water. The latter will have greater resistance than the first.

Measuring the resistance or conductance of these films is tricky. It's highly dependent on age of the coating, pressure used, humidity, etc. In would seem that defining a standard procedure to measure this property would be straight forward, however, it's seldom done!
