BRIGHT CHROME NEUTRALISER-306

Bright chrome  neutraliser - 306 offers  a simple method for  removing the  chrome  solution carried over on plated components  as  they  are transferred  from the drag-out tank after chrome plating. In  use,  it not only neutralises any free acid remaining  upon the surface of  the chrome plated articles, but also chemically reduces the residual chrome to easily removable and washable green trivalent chrome.  

The  bright chrome neutraliser-306 can also be used, very  effectively on  automatic nickel and chrome plating plant for the removal  of  any chromic acid  entrapped in jigs, thus preventing chromic contamination of the cleaning lines.
