Oxone™ PS-16

Also known as KPMS or potassium peroxymonosulfate, Oxone™ is a white granular product that provides non-chlorinated oxidation in a wide variety of applications.  It's safe to use in a production facility, in the environment, and even as a key ingredient in your denture cleaner!

Most notably, the active ingredient allows for efficient non-chlorinated oxidation as a pool shock, allowing less use of sanitizer and leaves the pool clean, clear, and swimmable nearly immediately.  The powerful oxidation as a microetchant in printed circuit boards improves process control in multi-step copper etching with a predictable rate to completion.  KPMS is of particular interest in metal plating and mining as it safely, economically, and conveniently oxidizes cyanide in waste streams.  These key benefits of rapid rate of reaction as well as non-chlorinated oxidation has allowed repulping papers with wet strength resins to move their processes to greener methods without sacrificing production time.

Oxone™ Potassium Monopersulfate

If strong oxidiation is needed, Oxone™ monopersulfate is the right choice for a wide variety of industrial and consumer application.  It is a peroxygen chemistry with a 4.7% active oxygen content that is a powerful oxidant (1.85V) without the presence of chlorine.  It is soluble in water and is fast dissolving.  It is also soluble in methanol, ethanol, acetone, DMF, ionic liquids and solvents like Phase Transfer Catalysts like dichloromethane, ethylacetate, and toluene.  ChemPoint partners exclusively with LANXESS Corporation on the white, granular, free-flowing powder form.

Metal Surface Preparation
Oxone™ is a free-flowing powder chemical microetchant for electronics and printed wiring board manufacturing industries.  Other benefits include:

  • Free-flowing powder
  • High etch rates that are uniform and predictable
  • Excellent bonding morphology
  • Well-defined surface topography
  • Contaminant removal
  • High rinsability
  • Long bath life with simple analysis and control
  • Better performance at lower temperatures, allowing for energy and cost savings
Metal Finishing & Hydrometallurgy
Oxone™ (KPMS) is also used in direct and indirect oxidation techniques in metal extraction, ore separation, hydrometallurgy, and other surface treatments of metals and metal alloys like alloy formation, lamination, copper plating, final finish, and flash etch.  It functions for the destruction of cyanides as well as the oxidation of the following materials:
  • Chromium
  • Copper Sulfide
  • Chalcopyrite
  • Cobalt
  • Nickel
  • Manganese
In non-ferous metal finishing applications, Oxone™ finds application in:
  • Etching or microetching surfaces to reduce thickness
  • Remove oxidation
  • Pre-clean prior to metal bonding or plating
Environmental Waste Streams
Most widely used in the oxidation of cyanide, reduced sulfur, and amine compounds, Oxone™ provides safety and convenience in handling.  In oxidizing hydrogen sulfide (H2S) in waste streams, KPMS allows for deodorizing a waste stream or stack via scrubbing without on-site manufacture or handling of hazardous ingredients like Caro's acid.  Analytical testing is still required to determine the effect on the waste stream to ensure complete removal of all compounds, including mercaptans, sulfides, disulfides, and sulfites.  

For metal plating or mining operations where the removal of cyanide is needed, Oxone™ can rapidly oxidize cyanide much more quickly than hydrogen peroxide, sodium percarbonate, sodium perborate, or sodium dipersulfate.  Particularly in dilute or small waste streams, Oxone™ based processes are convenient and economical - it is easy to transport and store Oxone™ compared to hydrogen peroxide, sodium percarbonate, sodium perborate, peracetic acid, sodium dipersulfate, chlorine, hypochlorite, or ozone which cannot be transported at all.
