A general-purpose blackening and browning concentrate for brass, bronze and copper alloys. Rapid reaction makes M20 ideal for use on manual finishing lines. Contains buffering agents which make the solution resistant to low level contamination or carry-over without affecting finish color or coverage. Use at 20% volume for black finishes; 10-15% for a full tange of pleasing brown tones.
