Etching agent B327, fine crystalline 100 g

Information: This product is intended exclusively for professional use in accordance with applicable legal regulations. It may only be purchased by a legal entity or a self-employed person with a valid business ID number

The B327 etching agent is a high-quality fine crystalline sodium persulfate intended for precise copper etching and printed circuit board (PCB) production. It is a popular alternative to ferric chloride because it allows cleaner work, creates precise outlines of conductive tracks, and minimizes undercutting of etched areas. The agent dissolves very quickly in water and does not crystallize out of the prepared solution, which contributes to a stable etching process. 

Thanks to the fine crystalline structure, the active substance is distributed evenly in the solution and the copper layer is removed uniformly. The result is sharp track edges, high precision, and a quality final appearance of printed circuit boards. The agent is suitable both for prototype production and for regular use in professional workshops and laboratories. :co

A 100 g pack is enough to prepare approximately 0.5 liters of etching solution. The agent is intended primarily for copper etching in PCB production and other applications requiring precise removal of the copper layer.

How to use B327 etchant
Dissolve 100 g of the agent in 0.5 l of water at a temperature of about 50 °C. Etch at 40 °C (max. 50 °C). Movement of the bath ensures faster processing. The etching solution must not be stored in hermetically sealed containers due to the risk of overpressure and bursting.
