Rust Inhibitor
Rust Inhibitor
Advanced Corrosion Protection Additives for Industrial Lubricants
Metal Passivation • Acid Neutralization • Water Displacement Protection
Rust inhibitors in lubricants are critical additives whose polar groups strongly adsorb onto metal surfaces, forming protective layers to block corrosive media. These advanced rust inhibitors provide unparalleled protection against corrosion in the most challenging industrial environments.
Our premium rust inhibitor formulations are engineered to meet the highest industry standards, offering exceptional salt spray resistance, acid neutralization, and water displacement capabilities for a wide range of applications.
- Metal Passivation: Salt spray resistance ≥800 hours without corrosion (ASTM B117).
- Acid Neutralization: Stabilizes TAN values (increase ≤0.2 mgKOH/g).
- Water Displacement Protection: 100% pass rate in 96-hour humidity cabinet tests (GB/T 2361).
- Synergistic Anticorrosion: Collaborates with antioxidants to extend metal fatigue life.

Specifications
Product | Application |
Synthetic Barium Sulfonate (T701) | Excellent humidity/salt spray resistance and water displacement; used in rust preventive oils and greases. |
Synthetic Sodium Sulfonate (T702) | Strong hydrophilicity and rust inhibition; suitable for cutting emulsified oils. |
Alkaline Dinonyl Naphthalene Sulfonate | Superior rust prevention for ferrous metals and acid neutralization; used in rust preventive oils and greases. |
Neutral Dinonyl Naphthalene Sulfonate | Good rust inhibition and demulsibility; applied in hydraulic and turbine oils. |
Benzotriazole | Excellent protection for non-ferrous metals (e.g., copper, aluminum); acts as a vapor-phase inhibitor and corrosion inhibitor in industrial circulating water. |
Alkenyl Succinic Acid | Effective in humidity resistance and open-panel exposure tests; widely used in turbine oils, hydraulic oils, and way oils. Limited by high acid value. |
Alkenyl Succinic Acid Ester | Ester-based derivative of T746; replaces T746 in acid-sensitive oils. |

Application Fields
Marine Equipment: Salt spray corrosion resistance (NACE TM0172).
Precision Bearings: Prevents white rust (roughness maintained at Ra ≤0.05 μm).
Power Equipment: Transformer oil copper corrosion ≤Grade 1 (IEC 61125 C1).
Military Preservation: 10-year ultra-long-term protection (GJB 145A-2018).
Scientific Formulation Protocol
Golden Ratio Formula for Rust Inhibitor Dosage:
Rust inhibitor dosage (%) = 0.05 × Metal surface area (m²/L) + 0.1 × Environmental corrosion index
Operational Guidelines:
Sulfonate Types: Require pre-emulsification (HLB value 8-12).
Vapor-Phase Inhibitors: Use in sealed environments (concentration ≥15 mg/m³).
Mixing Prohibition: Avoid simultaneous addition with high-alkaline detergents (interval >30 minutes).
Storage: Maintain temperature at 5-30°C (prevents crystallization).
Why Choose Rust Inhibitor?
“Our marine equipment exposed to saltwater environments showed zero corrosion after 18 months of continuous operation using these rust inhibitors. The protective film formation is exceptional.”
“The scientific formulation protocol for rust inhibitor dosage has reduced our additive costs by 22% while improving protection levels in our industrial lubricants.”
