Corrosion Inhibitors

Corrosion inhibitors are essential components in the formulation of water-miscible metalworking fluids. The primary function is to minimise the corrosive effects of water-based fluids on ferrous and non-ferrous metals. Besides the corrosion inhibitor components as a function of their chemical composition, they can also provide emulsification, lower foaming tendency and enhanced lubricity making them useful multifunctional additives. Metalworking fluid applications include soluble oils, semi-synthetic and fully synthetic fluids as well as cleaners.


​Corrosion inhibitors components provided by Lankem may be used to boost corrosion inhibition properties of water-based fluids for steel, iron, aluminium, other metals, and neat oil lubricants for ferrous based metals.


These products are based on phosphate esters, imidazolines and fatty acid esters:

  • Lanphos PE74 and Lanphos PE35 phosphate esters provide corrosion protection for ferrous metals and aluminium for soluble oil and semi-synthetic metalworking fluids. Lanphos TEP4 provides corrosion inhibition in the formulation of synthetic metalworking fluids.
