Additin® RC 4801

Applications

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


Mode of action:
Creating hydrophobic metal surfaces

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.
