Zinc Sulfonate Complex
Zinc sulfonate complex — a zinc-based sulfonate used as a rust inhibitor and surfactant in specialized lubricants, rust preventives and metalworking fluids, where zinc's properties add value.
The zinc sulfonate for specialized corrosion protection
Zinc sulfonate complex combines sulfonate surfactancy with zinc chemistry, serving as a rust inhibitor and additive in specialized lubricants, rust preventives and metalworking fluids.
Zinc sulfonate complex is a zinc-based sulfonate used primarily for its rust inhibition and surfactant properties in specialized applications. The zinc contributes corrosion protection and, in some systems, mild anti-wear character, making it useful in rust-preventive oils, certain lubricants and metalworking fluids. It is a specialty member of the sulfonate detergent family, distinct from the calcium, magnesium and barium grades used mainly for engine-oil TBN, and is selected where zinc chemistry adds specific value.
Zinc Sulfonate Complex — typical properties
Representative typical values for zinc sulfonate complex. Indicative only — exact values vary by grade and are confirmed on the TDS and batch COA.
| Property | Typical Value | Method / Note |
|---|---|---|
| Appearance | Brown to amber liquid | Visual |
| Zinc content | Grade-dependent | Refer to TDS |
| Total Base Number (TBN) | Low to moderate | ASTM D2896 · grade-dependent |
| Kinematic viscosity (100°C) | ~30–150 mm²/s | ASTM D445 |
| Flash point (COC) | > ~160 °C | ASTM D92 |
| Density (15°C) | ~0.95–1.1 g/cm³ | Typical |
| Sulphated ash | Grade-dependent | ASTM D874 |
Typical values for guidance only — not a specification. Request the TDS for the specific grade you need; the COA reports actual measured values for your batch.
