Gold - Elektrolyteedelmetallbaeder_gold

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.
