Trivalent Chromate Surface Conductivity

Can you tell me what the surface conductivity or the volumetric resistance is for Trivalent Chromate alone?

The answer to your question is that it would be variable from process to process. Then you would have variation in how the finish is applied and the process bath maintained.

What I am really getting at is the thickness of the chromate film will effect conductivity and different proprietary products will have different results. Further the application would include further variables,
not including the use of sealers, organic dyes, etc.
