Notes:

  • Do not plate over 0.1 micron.
  • Plating over copper or its alloys (brass) requires a barrier layer of 0.5 micron minimum of nickel then plate in 18 carat gold.
  • The ability to plate in recesses decreases as the amount of blackening agent is increased.
  • Plating rate decreases as the amount of blackening agent is increased.
  • We recommend that after use, the ruthenium plating solution is returned to its storage bottle in order to prolong the life of the mesh anode.
