Evonik REVOCOROS® AC 101 Corrosion Inhibitor
Categories: Other Engineering Material

Material Notes: REWOCOROS® AC 101 is a specially modified fatty acid monoethanol amine (MEA) condensation product based on oleamide.

Application: REWOCOROS® AC 101 is used as a corrosion inhibitor and co-emulsifier for water based metal working fluids (MWF). Manufacturer recommends REWOCOROS® AC 101 for semi-synthetic MWF in combination with non-ionic emulsifiers and boric acid-amine-blends. This will result in clean MWF and systems that are highly biostable. Furthermore, REWOCOROS® AC 101 can be used to formulate soluble MWF along with sodium sulfonates. To solubilize REWOCOROS® AC 101 in mineral oils, we recommend the use of low ethoxylated C16/C18 fatty alcohols for paraffinic oils and higher ethoxylated C16/C18 fatty alcohols for naphthenic oils.


  • REWOCOROS® AC 101 provides superior corrosion protection of the newly formed metal surfaces during the metal working process.
  • It increases the stability of metalworking fluids and allows for extreme dilution of emulsions without rust formation. These effects cannot be achieved with in-situ generated fatty acid MEA soaps.
  • Due to its characteristics as co-emulsifier REWOCOROS® AC 101 allows for a reduction of the total emulsifier amount.
  • This product provides metalworking fluids with excellent reserve alkalinity.
  • REWOCOROS® AC 101 improves the wetting properties of metalworking fluids.
  • It is not known to show any detrimental effect on the finished parts.
  • Furthermore, it is free of secondary amines. It complies with German TRGS 611.
  • REWOCOROS® AC 101 is a clear liquid product that conduces easy blending processes.
  • REWOCOROS® AC 101 is 90 % readily bio-degradable (total degradation according to OECD 301 D).
