Copper Processes

Cyanide Copper Solutions:


Used for the pre-plating of steel, zinc-based diecastings, aluminium, lead or its alloys, the cyanide copper strike is a hydroxide-free electrolyte. 

It gives a fine grained, matt to semi-bright deposit up to a maximum thickness of 5 µm.

Cyanide Copper SLOTOCOUP CC10

This cyanide based copper electrolyte produces bright, smooth and ductile deposits.

The throwing and covering power are excellent; the process is very suitable for the plating of profiled parts.

As it is hydroxide free, it is particularly suitable for the copper plating of zinc-based diecastings.  It is suitable for both rack and barrel applications.

Acid Copper Solutions:

Bright Copper SLOTOCOUP TB 50

A decorative acid copper process giving a mirror bright, highly levelled deposit.  Levelling performance is maintained even at low current densities.  This sulphuric acid based electrolyte has a stable additive system and wide operating parameters.

Operating temperature of the bath is 20-30oC (25oC) optimum and the current density varies between 1 and 6A/dm2

Deposition rate is 0.88 µm/minute at 4A/dm2.


A key factor in the success of SLOTOCOUP PC81 acid copper has been its suitability for the deposition of thick and very ductile deposits. 

Other advantages include its ability to withstand the most demanding thermal cycle tests and to operate over a wide range of current densities. 

Using a single additive system, which produces no detrimental breakdown products, the bath remains stable after being left idle for long periods.  Deposition rate is approximately 0.88 µm/minute at 4 amps/dm².

Bright Copper ACG 8

This acid copper electrolyte produces a very bright deposit with excellent levelling.

The process is controlled with a single additive making it very easy to control.

The plated deposit has a high deposition rate, very low internal stress and is soft which makes polishing very easy.

Alkaline Copper Solutions:

Alkaline Copper SLOTOCOUP CF 1800

SLOTOCOUP CF 1800 is an alkaline copper electrolyte free from cyanide for the
deposition of smooth, fine crystalline and ductile copper layers. The weak alkaline pH value
of the electrolyte allows direct coating of steel base materials with excellent throwing power and
adhesion. After copper plating in SLOTOCOUP CF 1800 an acidic copper- or nickel
plating can follow directly. SLOTOCOUP CF 1800 comes as a ready to use solution.


Copper Ancillaries:

Copper Sulphate Salt

This pure, anti-caking additive free, salt is available for the trouble free manufacture and maintenance of all copper sulphate plating solutions.

Copper Sulphate 300 g/l

This purified liquid concentrate provides trouble free manufacture and maintenance of all copper sulphate plating solutions.

Copper Oxide

A high purity cupric oxide with low chloride content for use in via fill electrolytes using MMO anodes

Copper Concentrate FC

A 32% w/w pure concentrate of copper methane sulphonate.

Copper Fluoborate 50%

A high grade 50% concentrate of copper fluoborate.

Copper Anodes OFHC

Developed for use in cyanide solutions

Copper Anodes Phos. De-oxidised 

Developed for use with copper sulphate plating solutions.

Sulphuric Acid Pure 1.84

Pure sulphuric acid, suitable for the maintenance of copper, nickel and a variety of processes.

Stripping Processes Copper:

Stripper L

Stripper L is an alkaline cyanide based process for the stripping of a variety of metals from steel.

This process is capable of effective stripping of nickel, electroless nickel, copper, cadmium, zinc and tin.

The base metal is not attacked so subsequent replating is possible without the need for further finishing.

Stripper L30

Two different versions of Stripper L30 can be made up.

The first version L30/1 is used for the immersion stripping of tin and tin-lead deposits from copper. 

The second L30/2 is used for the stripping of tin, tin-lead and copper deposits from stainless steel jigs and contacts.
