M-530 is an oil-based package of corrosion inhibitors for hydraulic or lubricating oils. M-530 is a rust preventative product, which provides excellent protection during operating conditions and intermittent operations.

M-530 is very effective for mineral and synthetic oils: naphthenic, iso-paraffinic, PAOs, among others.


  • Corrosion protection to ferrous and non-ferrous metals
  • Does not contain hazardous barium, chromate, nitrite, or phosphate inhibitors
  • High flash point
  • Low in toxicity and thermally stable, providing long-lasting corrosion inhibition
  • Passes through a 1 micron filter
  • Can be used in hydraulic applications
  • Provides protection in the presence of chlorides
  • When added at recommended concentration to hydraulic fluids, does not affect emulsification, pour point, or viscosity at low temperatures
  • Compatible with most mineral and synthetic oils
