Caswell Silver is a new type
of alkaline cyanide free silver plating solution
that will plate over nickel, sterling silver, gold,
rhodium, copper, brass and bronze. The system will
provide uniform color consistency and even coverage. |
It is important when silver plating to
realize what type of finish is required on the part.
If a highly polished surface is required, the part must
be buffed to a high shine before plating. If a matt
finish is required, then the part should be beat blasted
or buffed with something like a Britex wheel.
In our tank plating systems, pure silver
will be deposited on the part in 1 to 5 minutes, depending
on the thickness of plate required. The system uses
approx 2-6 volts and 1 amp per 16 square inches. The
system operates at room temperature, so no heater is
required.
Our cyanide free silver solution plates
substantially faster than cyanide silver and with superior
adhesion to cyanide silver. It plates with a brilliant
white color. The bath is operated at room temperature.
The steps to acheive a brilliant silver
finish are:
- Buff & Polish
- Degrease & Rinse
- Acid Activate (with battery acid, not supplied)
- Plate with Flash Copper (Steel, Pot Metal &
Pewter only)
- Plate with Silver
- Acid Activate
- Treat with Silver Conditioner (prevents tarnishing)
Potassium Hydroxide is used to raise the PH of the
solution when required. The system must be maintained
at a PH of 8.8-9.5. |
