Triple-s SM-277 is a heavy duty alkaline electro cleaner for the cleansing and de-scaling of ferrous metals prior to electroplating. SM-277 has an exceptional ability to remove rust, weld scale, and smut from metals at room temperature.

PRODUCTION ADVANTAGES:

  • Contains no cyanide or nitrate.
  • long tank life.
  • Very effective.
  • Room temperature.
  • Can be used with periodic or reverse current.
  • Heavily fortified with emulsifiers and dispersants for removal of fabricating oils and compounds.
