Etching agent, Sodium Persulfate B-327 1kg, plastic bottle

Description

Sodium persulfate B327 is used to dissolve and etch printed circuit boards and copper. It is an excellent alternative to ferric chloride. The even distribution of fine crystalline powder ensures sharp contours and minimizes etching. Sodium persulfate B327 from AG Termopasty in trace amounts includes i.a. manganese, iron, ammonia and active oxide. Remember not to keep the product near flammable substances.

Usage

Dissolve the preparation weighing 100 g in 500 ml of water at 50°C. Etch at 40°C (max. 50°C). The movement of the bath ensures faster digestion. Etching agent solution must not be stored in hermetically sealed containers due to the risk of overpressure and rupture.
