Ferric perchlorid. Ready to use. 40% liquid solution .
For security reasons during transport, these products must be removed at our premises.
The solution has more than 50 g/l copper capacity and etching rates of about 30 down to 10 µm/minute.
Performance will be best at about 40-50 °C, but other than sodium persulfate, etching can be done even at room temperature.
Ferric chloride tends to deposite a mud of copper chloride. This can be overcome by adding small portions of hydrochloric acid to the used (never to the fresh!) liquid.
You can dilute the 40% liquid solution with 450ml water per litre down to 30 %. According to Bungard tests the fastest etching rate was achieved with a 30 % solution.
