Evonik is the sole North American producer of quality ammonium, potassium and sodium persulfates, specially designed for the cleaning and preparation of printed circuit boards (PCBs). Thermally stable, economical, and an ability to maintain an extended shelf life are just a few qualities that make our printed circuit board etching chemistries stand out from the rest
The oxidation power of persulfates is used to clean and microetch a variety of printed circuit board substrates. Persulfates are important oxidants in plating and coating processes. They are also etchants for nickel, titanium, and zinc alloys. Persulfates are used to clean and mill aluminum, brass, copper, and many other metal surfaces prior to plating or adhesive bonding.
Sodium persulfate acts as a polymerization initiator in polymer chemistry, as an etchant and cleaner in the manufacturing of printed circuit boards, as a booster in hair bleaching formulations in cosmetics.
Potassium persulfate is used as an initiator for emulsion polymerization reactions, in the preparation of acrylic, vinyl, styrene, neoprene, styrene-butadiene and other resins. It is also used in depolymerization in modification of starch, as a booster in hair bleaching formulations in cosmetics and as a gel breaker in the oil and gas industry.
