Fine crystalline agent b327/100g etchant

Etching agent for printed circuits and copper. An ideal alternative to ferric chloride. The agent dissolves very quickly and does not crystallize from the solution. Etches evenly ensuring sharp contours and minimizing under-etching.

Usage:
Dissolve the preparation in 0.5 l of water at 50°C. Etch at 40°C (max. 50°C). Bath movement ensures faster etching. The etching solution must not be stored in hermetically sealed containers due to the risk of overpressure and rupture.
Packaging: 100g
