K-CORR® RUST & CORROSION INHIBITORS

K-CORR® rust and corrosion inhibitors,based on amino acid derivatives, offer formulators of industrial lubricants both ashless and calcium salt containing products that exhibit excellent corrosion protection, good demulsibility and a low acid number.

Performance

In addition to excellent rust and corrosion protection, K-CORR® inhibitors have demonstrated unique performance characteristics in specific systems, including:

Neutral Behavior on FZG Performance
Excellent Thermal Stability (Cincinnati Milacron Test)
Good Hydrolytic Stability (ASTM D 2619)
Synergism With Selected EP/AW additives (ASTM D 4172)
Enhanced Oxidation Stability (RBOT)
