Metal Deactivators

At A Glance

Our IRGAMET® Metal Deactivators suppress chemical attack on the surface of copper and copper alloys, as well as protecting copper surfaces from blackening upon exposure to sulfur-containing lubricants at high temperatures. They contribute to longer oil lifetime by passivating the metal surface and avoiding residues that act as catalysts for radical formation. 

Typical Applications

  • Driveline fluids
  • Industrial gear lubricants
  • Hydraulic fluids
  • Turbine lubricants (industrial and aviation)
  • Compressor oils
  • E-Mobility fluids
  • Refrigeration lubricants
  • Marine lubricants
  • Greases
  • Metalworking fluids
Typical applications with metal deactivators
