Potassium monopersulfate CAS number 37222-66-5

Potassium monopersulfate compound salt is a free-flowing white powder granular peroxide, easily soluble in water,

composed of potassium monopersulfate, potassium bisulfate, and potassium sulfate. Its oxidizing function derives from its highly acidic chemical properties, making it a stable,

convenient, and versatile excellent acidic oxidant and disinfectant.

The highly effective non-chlorine oxidation provided by potassium monopersulfate, combined with its safety in handling, makes it widely applicable in various fields: used in copper deposition, electroless plating, direct plating,

pre-treatment of boards coated with photoresist films, pre-treatment of board surfaces before solder mask application, and pre-treatment of inner layer board surfaces.

Etchant for circuit boards.
