Bright Rhodium Bath, Prod-ID: NC700

Bright Rhodium bath NC700

Rhodium NC700 deposits mirror shining, brilliant white, magnificent hard and abrasion resistant rhodium layers. It is additionally characterized by high covering speed and excellent throwing power. Furthermore the NC700 Ultra Bright layer thicknesses of up to 1.5 micron can be deposited crack-free.

Rhodium can be directly deposited on silver, gold, copper and copper alloys, nickel and nickel alloys. When plating tin, lead, zinc, aluminium and iron, intermediate nickel coatings of some micron thickness are absolutely essential. Strike nickel plating is advantageous with all substrates.

Rhodium content: 2 g Rh/100 ml
