Applications

  • Tin/Lead & Tin/Lead alloy plating  
  • Tin plating
  • Immersion and spray stripping of  Ni, Sn, Pb, Sn/Pb, Cd  Cu , Zn 
  • Electropolishing
  • Regeneration of ion exchange resins

A more friendly environmental grade

E-Pure® MSA is replacing most of classical acids used in Sn or Sn/Pb electroplating baths such as Phenol Sulfonic Acid (PSA), Fluoroboric acid (HBF4), Sulfuric acid (H2SO4) and Halides, and frees processes from toxic lead and hazardous fluoborates. With E-Pure MSA®, bath can operate with lower metal content and allows for reduced waste, sludge and fewer residues and effluents. E-Pure® MSA also offers the possibility to recycle electrolytes.
