ARGUNA® 3230 Cyanide-free Fine Silver Electrolyte

ARGUNA® 3230 Cyanide-free Fine Silver Electrolyte

For deposition of fine silver layers

ARGUNA® 3230 is an alkaline, cyanide-free silver electrolyte for the deposition of technically functional silver layers. The layers are also suitable for decorative applications.

As the electrolyte does not contain any toxic cyanide compounds, it is therefore easier to use under the increasing environmental and safety requirements. Especially for the medical technology cyanide-free systems are often required.

The deposited layers are excellently suited for soldering and wire bonding applications as well as for electrical contacts e.g. in power electronics or high current technology.

ARGUNA® 3230 is ideal for rack and barrel applications. Copper materials can be coated directly, without pre-silver.
