Castrol Corrosion Inhibitor™ N 213 is a solvent free highly effective vapour phase corrosion inhibitor especially
recommended for ferrous metal protection in enclosed systems. It contains a blend of mixed amines and their salts, the
vapours of which give corrosion protection by absorption as a molecular film on metal surfaces.

Castrol Corrosion Inhibitor N 213 can be used when corrosion protection of existing product needs to be improved
especially in enclosed environments. It is especially developed to improve performance of Castrol Alpha SP gear oils in
use. It can be successfully used for the internal protection of engines and gearboxes, fuel tanks, hydraulic systems,
pipes and export packing, pumps and compressors. Since protection is derived from the vapor it can only be fully
effective in an enclosed syst

Castrol Corrosion Inhibitor N 213 should only be used after consultation with Castrol’s Service Representative.
Depending on the corrosion protection desired, the recommended dosage can vary from 0.17 to 0.35 liter per cubic
meter of the volume of the enclosure.
