Electrolyte for bright white pure silver layers
The silver electrolyte ARGUNA® 629 deposits shiny, bright white coatings and is excellently suited for both technical and decorative applications. The electrolyte exhibits very good depth scattering and can also be used at higher temperatures. Furthermore, it convinces by a very wide working window. When depositing on nickel, no pre-silvering is necessary.
The bright silver electrolyte is suitable for both rack and barrel plating lines. The bright white deposited layers have no blue tint.
