Additin® CI / Sulfonates

PROTECTION FOR METAL SURFACES

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.
