For export outside the UK and the EU only. Requires further additions in order for it to function.
Please refer to the Tech Specs and Product Details for more information.

This solution can be used for gold plating very adhesive layers on to difficult-to plate metals such as chrome, surgical steel and dental alloys. Standard swabs can be used with this solution, however for longer life we recommend using the S-Type Swab which can be purchased by clicking on the link in the ‘Related Products’ below this tab.
Gold Strike is mainly used as an adhesive undercoat for other metals such as gold, silver, palladium and platinum and should not be plated over 0.1 microns.
Click the ‘Tech Specs’ tab for instructions on how to prepare 1 litre of Gold Strike from the export only version.

Gold content: 2 grams per litre

Our Gold Strike Brush (export outside UK and EU only) plates adherent layers of gold straight on to chrome without stripping and difficult to plate stainless steel alloys. Particularly useful for plating super adherent key layers for subsequent plating of thick layers of gold of 3 microns and above. Please use a Carbon Electrode, which can be purchased by clicking on the link in the ‘Related Products’ section below this panel.

Our Gold Strike is very adhesive. To demonstrate this here is an example of the sellotape test – in section A of the picture, the tape is stuck to the surface of our freshly plated Gold Strike layer and then in section B of the picture, the sellotape is removed. The gold layer stays on the surface of the work with no traces of gold on the sellotape.

Other difficult to plate metals such as tungsten can also be plated with our Gold Strike.

  • Strike plate chromium, tungsten, dental alloys and more
  • Recommended thickness: 0.1 micron

Notes:

  • The specifications above relate to the final mix with sulphuric acid added not to the as-shipped version.
  • When plating in recesses, we recommend using the using the Plating Pen (8 – 10 volts, Fibre Nib).
  • Plating rate decreases considerably below 20 °C
  • We strongly advise against the use of stainless steel anodes for most of our plating processes
  • Plating rates are calculated over a sample area which is permanently covered by swab.
