Corrosion Inhibitors

Corrosion Inhibitors can sustainably prevent oxidation and the formation of rust on metallic materials. Corrosion inhibitors typically consist of polar chemical compounds that form a protective layer on metal surfaces to protect them from corrosion. By forming this barrier, they prevent moisture, oxygen and other corrosive substances from coming into contact with the metal.

Corrosion inhibitors in the lubricant industry are used in a wide range of industrial applications. In the automotive industry, for example, corrosion inhibitors are used in engine oils, coolants, and other fluids to protect sensitive engine parts from rust and corrosion. They are also crucial in the aerospace industry, where they protect aircraft and spacecraft from the extreme conditions of flight and the space environment. Corrosion inhibitors are also used in hydraulic systems, cooling circuits, lubricants for machinery and equipment, and in marine and offshore applications. Their use not only helps to extend the service life of machinery, but also reduces downtime and maintenance costs.

Corrosion Inhibitors of the LUBIO® CI series help in the formulation of advanced lubricants that lubricate and protect the material at the same time. The additives in the LUBIO® CI series make a decisive contribution to the longevity of components. The chemistry of the corrosion inhibitors of the LUBIO® CI series is based on a polar framework. While LUBIO® CI-2 als organische Polycarbonsäure als Feststoff vorliegt, zeichnen sich LUBIO® CI 3, CI 4 and CI 9 are liquid additives of high polarity. All corrosion inhibitors are water-soluble and therefore also suitable for water-based MWFs.
