Antiquing and Blackening Solutions

Metalline Corporation manufactures several products that will provide a decorative Black finish over brass and copper alloys.  These Black deposits are relatively soft and can be highlighted, relieved or antiqued.  Listed below is a brief description of the blackening products for brass and copper alloys. 

  • CB-1 is an alkaline powder that is added to water to produce a black oxide finish on copper alloys. CB-1 produces a consistent black finish that is an excellent base for highlighting or antiquing. The CB-1 oxide finish is more stable and often more adherent than those produced by sulfides or black nickel plated deposits. To effectively blacken parts with a copper content between 65-90%, Metalline BB-2 is utilized as an activator prior to CB-1.
  • BB-2 is an alkaline powder that is added to water to produce a black oxide coating on brass. BB-2 produces a consistent black finish that is an excellent base for highlighting or antiquing. The BB-2 oxide finish is more stable and often more adherent than those produced by sulfides or black nickel plated deposits. To effectively blacken parts with a copper content between 65-90%, Metalline BB-2 is utilized as an activator prior to CB-1.
  • ECLIPSE® BN-99 is a single component powdered blend of metallic salts that will provide a beautiful Black Nickel plated deposit over brass, copper and nickel plated deposits.  A range of colors from light grey to jet black can be consistently achieved by adjusting current and immersion time.  The ECLIPSE® deposit can be highlighted and antiqued, and a final protective clear coat can be applied to enhance durability.
