Sodium persulfate B327 1L for etching and dissolving printed circuits
Description
Sodium persulfate B327 - from AG TermoPasty is an agent in the form of a crystalline, fine powder for etching and dissolving printed circuits and copper. In trace amounts, it includes, among others manganese, iron, ammonia and active oxide.
How to use:
500 g for 2,5 l water
Etching agent for printed circuit boards and copper. The perfect alternative to iron chloride. The agent dissolves very quickly and does not crystallize out of the solution. It etches evenly, ensuring the sharpness of contours and minimizing undercutting.
Directions for use: Dissolve the preparation in 2.5 liters of water at 50 ° C. Etch at 40 ° C (max. 50 ° C). The movement of the bath ensures faster digestion. The etching solution must not be stored in hermetically sealed containers due to the risk of overpressure and cracking.
