What it is and what it does. Formaldehyde (formalin, 37%) is the reducing agent of electroless copper plating and a component of some electroless silver systems.
- Colourless clear liquid with a pungent odour; supplied as a 37% aqueous solution, often with a small amount of methanol as stabiliser.
- In electroless copper it reduces the copper complex to metallic copper on the activated surface.
- It is a carcinogen and a sensitiser, so it requires effective ventilation and monitoring.
Typical Use in a Plating / Finishing Line
| Item | Typical guidance |
|---|
| Electroless copper | As specified by the bath formulation, dosed continuously |
| Make-up dilution | Handled in a ventilated area with fume extraction |
| Safety | Vapour monitoring and health surveillance where the process runs continuously |

Buyer Questions We Answer Every Week
| Question | Answer |
|---|
| Why does the drum have a white deposit? | Paraformaldehyde has formed from the vapour; it indicates a cold store and a poorly sealed drum. |
| Can it be replaced? | Alternative electroless copper reducing systems exist (glyoxylic acid, hypophosphite) but the process must be re-validated. |
