Corrosion inhibition additives

PROTECTION FOR METAL SURFACES

APPLICATION

In tribological systems corrosion cannot be avoided and must be pre- vented 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 syn- thetic 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, special Additin® CI products are available for applications in highly aggressive environments. They are equipped with additional alkaline reserves to neutralize any fumes contributing to corrosion.
