Sodium Persulphate

Copper Etchant

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.

Directions

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.
