Platinum Q Salt® - Johnson Matthey Chemical Products

Platinum Q Salt®
Product name
Platinum electroplating
solution
This system is used to produce bright and highly adherent
deposits of low stress and low porosity platinum. It has the
added advantage of being non-toxic and non-explosive.

Bath preparation
The bath is supplied as a solution containing 5 g/l of platinum.
This solution will have a pH of 10.2 - 10.8 at 20°C. The bath
should be heated to the operating temperature of
91°C - 93°C, and the pH adjusted to the working range of
10.0 - 10.6 (optimum 10.5). This adjustment can be made by
the addition of sodium hydroxide solution (10 % w/v) to increase
the pH. Regular addition of demineralised or distilled water is
necessary in order to maintain the volume of the bath.
Replenishment
The platinum concentration of the bath should be maintained
between 4 g/l and 6 g/l by adding Platinum Q Salt® Pt 20Q
replenishing solution as required. Product code 155067, which
is pH adjusted.
Metal preparation
Components should be degreased and cleaned by means of a
procedure appropriate to the substrate in question. The bath has
been used to plate copper, gold, nickel, titanium, stainless steel
and super alloys.

Cathode current density:
0.2 - 0.7 A/dm2
(optimum 0.5 A/dm2)
It is important to maintain the stated temperature range. This is
because the cathode current efficiency is substantially reduced
at temperatures below 89ºC. Regular checks are essential to
ensure that the recommended pH range is maintained.
