Sodium Persulfate is a good replacement for Ammonium Persulfate for its
compatibility with etch resist pens. Sodium Persulfate will not remove etch
resist ink and like Ammonium Persulfate crystals, are used as an alternative to
the traditional ferric chloride to produce a cleaner copper etchant solution.
Mixed product must be stored in a vertical container.
Dilute crystals slowly into 4 liters of water using a glass, plastic or
stainless steel container. Stir until completely dissolved. To make less than 4
litres, dissolve 250 grams per liter of water.
