Extreme pressure/anti-wear additive with emulsification and corrosion inhibiting properties

Hordaphos 774

Hordaphos 774 is an efficient EP/AW additive with emulsification as well as corrosion inhibiting properties for ferrous metals and aluminium alloys. It is used for metal working fluids (emulsions, semi-synthetic, neat oil), rolling oils and emulsions and fire-resistant hydraulic fluids.
  • Excellent lubricity and EP/AW properties
  • Good emulsification properties
  • Good corrosion protection of steel
  • Contributes to inhibition of staining on aluminium
  • Existing metal working fluids for steel can be upgraded by adding Hordaphos 774 for machining aluminum
  • Reduces cobalt leaching
  • Hard-water stable
  • Water-dispersible
