Catalytic Passivation ®
Catalytic Passivation (CP) is a process that temporarily deadens the ionic charge on metal ions dissolved in rinse waters.
CEC discovered this quite inadvertently (like the inventor of Post-It Notes) while testing a combination of media meant to change the valence of hexavalent chrome to trivalent. That didn’t work, but we noticed that the hexavalent chrome was a lot LESS interested in plating out after being exposed to the media we were testing.
More details on this once the ND document is signed by CEC and your company officers.
