RUST & CORROSION INHIBITOR
OCN 958 is oil
soluble ashless Amine based rust inhibitor recommended for turbine
oils, Circulating oils, hydraulic oils at 0.035 to 0.10% w/w. it also gives
excellent Performance in greases, automotive and other synthetic oils at
variable dosages depending upon the final requirements. It can be used as a
rust inhibitor/friction modifier in first factory fill engine to meet
D.B.Corrosion test at 0.25 -1.0 %( Running in oils).

rating 0, no rust.
with conventional succinic acid half ester type rust inhibitors, OCN -958 has
following additional performance benefits.
1.It gives better performance at lower
concentrations and also cost effective.
maximum protection due to high thermal stability.
3. Effective on ferrous and non ferrous metals.
4. Easily miscible and flowable liquid.
5. It has excellent reserved alkalinity which
protects oil against degradation &
acid /sludge formations.
6. Even at higher concentration s it does not
allow gum and lacquer/varnish formation.
7. Excellent inherent dispersancy which help
in preventing deposit formation.
8. It prevents catalytic effect of the metal
at higher temperatures.
9.Compatible with all conventional
automotive and industrial additives
