Hordaphos 145

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

Edition Date :
October 07, 2022
Hordaphos 145 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 emulsions and fire-resistant hydraulic fluids (HFA-E).
Performance depends to some extent on the amine chosen for naturalization and can be boosted by combining it with esters, especially TMP-trioleate.


  • Excellent lubricity and EP/AW properties
  • Good emulsification properties
  • Good corrosion protection of steel
  • Contributes to inhibition of staining on aluminium
  • Forms a protective layer on aluminum surfaces
  • Existing metal working fluids for steel can be upgraded by adding Hordaphos 145 for machining aluminum
  • Minimizes copper and cobalt leaching and helps to protect cutting tools
  • Hard-water stable
  • Low foaming
  • After neutralization no skin or eye irritation
  • Broad registration status

Life Cycle

Hordaphos 145 has been approved the EcoTain label. The product provides the benefits at each step of the product life-cycle:

Sustainable Design

  • Product based on vegetable alcohol
  • Renewable share is ca. 47%
  • Boron-free and DEA-free

Responsible Process 

  • Resource efficiency due 99% yield
  • Minimized waste generation
  • Certified for safety & quality according to ISO 9001, ISO 14001 and OHSAS 18001 
  • Global production (China, Brazil. Germany, India, USA) can help to reduce transport

Safe & Efficient
