Tribological systems need to be protected against corrosion by appropriate additivation. The Additin® Corrosion Inhibition (CI) range includes ash-containing and ash-free products to inhibit corrosion.
The Additin® CI range offers a number of desirable characteristics:
Excellent corrosion inhibition
Demulsibility in hydraulic oils
Antiwear performance in gear oils
Water resistance in greases
Detergency in engine oils
Corrosion inhibition additives in the Additin® CI range, such as synthetic calcium alkyl benzene sulfonates, are adsorbed on the polar metal surface to form a water-repellent and protective film, thereby effectively reducing corrosion.
Certain acidic fumes, such as sulfur dioxide, are well known for their accelerating effect on corrosion. To neutralize their impact, Additin® CI products are recommended for all applications in highly aggressive environments. They are equipped with additional alkaline reserves to neutralize any fumes contributing to corrosion.
