MoDTP (Molybdenum Dithiophosphate)
MoDTP (molybdenum dialkyldithiophosphate) — an oil-soluble molybdenum additive delivering anti-wear, antioxidant and friction-reducing performance. Multifunctional protection from one molecule.
The multifunctional molybdenum additive
Oil-soluble molybdenum additives are prized because one molecule delivers anti-wear, antioxidant and friction-reducing performance at once. MoDTP brings all three with its phosphorus-containing structure.
MoDTP (molybdenum dialkyldithiophosphate) is an oil-soluble organomolybdenum additive that provides anti-wear, antioxidant and friction-reducing performance. Under load it forms a low-friction molybdenum disulphide (MoS₂) tribofilm at metal contacts, reducing both wear and friction — the latter supporting fuel economy. Its phosphorus content also contributes anti-wear character. MoDTP is used in engine oils, including diesel oils, and industrial lubricants where multifunctional molybdenum performance is valued. It is part of the anti-wear agents range and is often used with ZDDP and friction modifiers.
MoDTP (Molybdenum Dithiophosphate) — typical properties
Representative typical values for MoDTP. Indicative only — exact values vary by grade and are confirmed on the TDS and batch COA.
| Property | Typical Value | Method / Note |
|---|---|---|
| Appearance | Amber to dark liquid | Visual |
| Molybdenum content | ~8–11 wt% | Grade-dependent |
| Phosphorus content | Present | Anti-wear contribution |
| Sulphur content | Present | MoS₂ film former |
| Kinematic viscosity (100°C) | ~10–40 mm²/s | ASTM D445 |
| Flash point (COC) | > ~150 °C | ASTM D92 |
| Function | AW + AO + friction reduction | Multifunctional |
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.
