Black Chrome Electrolyte Caswell Black Krome

Caswell Black Krome – Black Chrome Electrolyte

With Caswell Black Krome® you can easily apply a deep black chrome look to parts such as car emblems, hinges, rims, musical instruments and fishing tackle. The electrolyte is ready-to-use, requires few steps and quickly creates a characteristic black finish that stands out from standard chrome. Ideal for restoration, custom builds and decorative applications.

Black Krome® does not contain chromium or nickel in the electrolyte and is therefore pleasant to use in the workshop. Over nickel, the hue becomes smoky metallic, while over copper, it becomes deeper black. For added protection, the layer can be finished with wax, oil, or a clear coating.

The electrolyte is available in:

• 1 liter
• 2 liters
• 5 litres

Setting up the bath and chrome it yourself

Chrome plating parts black yourself with this electrolyte is easy.

1. Fill a suitable plastic or glass tank with the Black Krome electrolyte
2. Hang two stainless steel anodes in the bath and turn on agitation with pump or air
3. Bring the bath to 21 to 60 degrees Celsius and aim at 60 degrees for best results
4. Connect the red plus wire of the power supply to the anodes and leave the power supply off
5. Attach the workpiece to a stick resting on the edge of the bath, dip it in the electrolyte and connect the black minus wire to the object
6. Measure the surface to be chromed and set the power supply to 0.4 amps per 10 cm², the process will now start
