Multi-metal corrosion inhibitor & EP/AW additive

Hostacor ITD

Hostacor ITD is a versatile performance additive for metal working fluids and lubricants. Besides of being an effective EP/AW additive, it provides excellent corrosion protection for steel and aluminum alloys while reducing copper and cobalt leaching.  
Hostacor ITD is recommended for metal working fluids (emulsions, semi-synthetic neat oil), rolling oils & emulsions, fire-resistant hydraulic fluids (HFD, HFD-U) and gear oils.

  • Excellent lubricity and EP/AW properties
  • Excellent corrosion protection of steel
  • Outstanding inhibition of corrosion and staining on aluminium
  • Forms a protective layer on aluminum surfaces
  • Existing metal working fluids for steel can be upgraded by adding Hordaphos MDIT for machining aluminum
  • Minimizes copper and cobalt leaching and helps to protect cutting tools 
  • Hard-water stable
  • Water-dispersible
  • Low foaming
  • Broad registration status
