Termopasty B327 sodium persulfate is used for etching printed circuit boards and copper sterilization. It dissolves easily and does not crystallize out of the solution, while providing uniform etching and well-defined outlines. It is an alternative to ferric chloride.
To prepare the solution, dissolve the product in 0.5 litres of water at 50 °C. Etch at 40 °C to 50 °C; agitating the bath speeds up the process. Do not store the etching solution in an airtight container, as this may cause excessive pressure and cracks.
