Clear selection

Silver Tank Plating Solution HB is ideal for building up thick layers of semi-bright to matt silver. It contains a greatly reduced level of cyanide – only one hundredth compared to that of normal cyanide- containing silver plating solutions. Because of this, it can be transported worldwide. Thicknesses of over 500 microns can be plated. Silver concentration: 35 grams per litre.
Please note that all orders come with 10ml of Silver Tank Starter HB and a 1ml pipette free of charge.

This silver tank plating solution can deposit layers of pure silver of up to 500 microns and more. For best results, pre tank plate a layer of copper to a minimum of 50 microns, using our copper elecroforming solution.

Silver Tank Plating Solution – HB


Features Benefits
Designed to be used with our electrode ring, fitted with 6 silver electrodes. Plates fast – over 1 micron per minute is possible.
Thick deposits possible. Especially useful when electroforming.
Ductile plate. No lifting or cracking at elevated thicknesses. Especially useful when electroforming.
Room temperature operation. Can be used at room temperature especially at lower plating rates.
No need for anode bags. Saves on maintenance and gives more room for work in the beaker/bath.
The silver from the silver electrodes replenishes the silver plated out from the solution. Low maintenance.

  • Higher plating speeds can be obtained at higher temperatures (30 – 35 °C) and higher agitation.
    Excessive current (amps) can result in a burned deposit or passivation of the silver anodes
    resulting in an increase in voltage and large decrease in the current.
  • As the silver electrodes erode, the maximum current (amps) will also decrease.
    Increased agitation, temperature or both will be necessary to retain the same current.
  • Plates semi-bright up to 10 microns; over 10 microns, satin finish and above 50, matt.
  • In extended testing, the quality of the deposit increases with solution age.
  • Coating is easily burnished either in a barrel or by hand to a mirror-bright finish.
  • Plating rates are calculated over a sample area whilst in contact with the swab.
  • After periods of inactivity (weeks), filtration is strongly recommended and an addition of
    Silver Tank Starter HB – please see table below:

How much Silver Tank Starter HB to add:

Tank/beaker size Volume of Silver Tank HB to add
250ml 1ml
500ml 2ml
1 Litre 4ml
2 Litre 8ml
5 Litre 40ml

Further notes:

  • If the solution has not been used for more than a few weeks, filter then add the required amount of Starter.
