Barium Dinonylnaphthalene Sulfonate Corrosion Inhibitors
Ultimate Hydrocarbon-Soluble Corrosion Protection for Critical Systems
Multi-Metal Defense • Vapor-Phase Protection • Radiation Resistant
It is mainly used to prepare rust-proof oil, instrument oil, papermaking machine oil, diamond oil, turbine oil, hydraulic oil, water-displacement rust-proof liquid, grease and other industrial lubricants used in water. This product can also be used as an anti-rust additive for engine fuel.
Product Introduction
Our Barium Dinonylnaphthalene Sulfonate corrosion inhibitors deliver unrivaled hydrophobic corrosion protection through their unique polynuclear aromatic structure. Engineered for critical hydrocarbon systems, these premium corrosion inhibitors form ultra-thin (<0.2μm) self-assembling films that provide complete metal coverage even in vapor-phase environments while resisting wash-off in fuel/lubricant systems.
This product has good rust resistance, lubricity, wear resistance, and oil solubility, with a certain acid neutralization ability. It offers excellent rust resistance for various metals, especially ferrous metals, making it ideal for critical industrial applications.
Product Features
■Good rust resistance■Good oil solubility and compatibility■Has a certain acid neutralization ability
Key Features
- Vapor-Phase Protection
100% rust prevention in ASTM D1748 humidity jars.
- Acid Neutralization
Neutralizes 12 mgKOH/g of organic acids (ASTM D664).
- Multi-Metal Defense
Protects 12+ alloys including magnesium and cadmium (ASTM D665 variants).
- Hydrocarbon Solubility
0.01% haze in jet fuel (ASTM D4176).
- Radiation Resistance

Molecular Innovation
Dinonylnaphthalene sulfonates form lamellar liquid crystals that self-orient on metal surfaces – creating 0.18 nm-thick molecular barriers (XRD-validated d-spacing 1.8 Å). This unique structure makes our corrosion inhibitors exceptionally effective in hydrocarbon environments.
The self-assembling nanolayers provide complete surface coverage and maintain protection even under extreme conditions, including radiation exposure and high temperatures.
