METAL PROTECTION THROUGH CORROSION INHIBITION


The REWOCOROS® brand comprises a broad range of multifunctional corrosion inhibitors for the formulation of metalworking fluids and non-flammable hydraulic fluids.


These products are being used in soluble oils, semi and full synthetic fluids as well as cleaners. They do not only provide excellent corrosion inhibition but additional benefits such as co-emulsifying or wetting properties or lubricity enhancement. We also offer products that are suitable for the processing of aluminum and other non-ferrous metals. 

Our portfolio includes  

  • Fatty acid amides

  • Boric acid blends 

  • Carboxylic acid derivatives 

  • Alkanol amides 

  • Phosphoric acid esters

In addition to the conventional test methods like the filter chip test or the bimetallic corrosion coupon test Evonik uses the impedance spectroscopy in order to evaluate customer needs and develop new solutions.
