Gold - Elektrolyte
Gold electrolytes from METAKEM are used for technical and decorative applications for the depositing of pure gold layers. These electrolytes are either cyanide based or cyanide-free based on ammonium gold(I) sulphite - covering nearly the complete pH-value spectrum.
Gold-SP
Colour gold electrolytes on cyanide base for the selective pen-/brush-electroplating – available colours: red, rose, yellow and green.
| Bath type: | Low alkaline, cyanide-based |
| Gold content: | 20 g per litre |
| Layer: | Gold |
| Bath temperature: | Room temperature (20-30 °C) |
| Voltage: | Gold-SP-red 4-10 V Gold-SP-rosé 4-10 V Gold-SP-yellow 8-15 V Gold-SP-green 4-15 V |
| Type of application: | Selective pen-/brush-electroplating |
| Delivery form: | 2g Au per 100ml-bottle |
Gold-VA
Gold-VA is a strong acidic cyanide based gold electrolyte. It is used for the strong adhesive direct gold plating of stainless steel without the pre-plating / -striking of an intermediate layer. In addition, the strong activating effect of Gold-VA even allows for the plating of passive materials.
| Bath type: | Strong acidic, cyanide-based |  |
| Gold content: | 2 g per litre | |
| Layer: | Gold | |
| Max. layer thickness: | 0.2 µm | |
| pH-value: | 0.3 | |
| Bath temperature: | 25 °C (15-35 °C) | |
| Current density: | 4 A/dm2 (1 - 10 A/dm2) | |
| Type of application: | Stainless steel plating, adhesive layers |
|
| Delivery form: | Make-up: Gold-VA Make-up + Replenisher Replenishment: Gold-VA Replenisher |
Gold-SF
Gold-SF is a sulphite-based gold electroplating bath with a neutral pH-value. Due to its extremely low chloride content this ultrapure bath shows even after long ultraviolet light exposure a high bath stability. Although generally used in the jewellery sector, uses can also be found for industrial applications such as dental electroforming etc.
| Bath type: | Neutral, sulphite based |  |
| Gold content: | 10-15 g per litre | |
| Layer: | Gold 99.9% | |
| Max. layer thickness: | max. 500 µm | |
| pH-value: | 7.5 | |
| Bath temperature: | 60 °C (55-65 °C) | |
| Current density: | 1 A/dm2 (0.1 - 1.5 A/dm2) | |
| Type of application: | Jewellery, electroforming | |
| Delivery form: | Make-up: Gold-SF (15 g Au / L) Replenishment: Gold-SF-R (100 g Au / L) |
Gold-CPB
Colour gold bath with a broad range of colours depending on the chosen colour additive solution. Gold-CPB has a low gold content - designed for the deposition of thin gold layers.
| Bath type: | Colour gold bath |  |
| Gold content: | 1 g per litre | |
| Layer: | Gold | |
| Max. layer thickness: | 0.2 µm | |
| pH-value: | 4-5 | |
| Bath temperature: | 60 °C | |
| Current density: | 5 A/dm2 (1-5 A/dm2) | |
| Type of application: | Jewellery, watches spectacle-frames |
|
| Delivery form: | Make-up: conductive salt + KAu(Cn)2 Replenishment: KAu(Cn)2 |
The following colours can be deposited by addition of different colour additive solutions: green, yellow, rose, red.
