Phosphorus-Nitrogen Based Lubricant Additive With High Oxidation Stability And Extreme Pressure Protection ( BSD-3918)
BSD-3918 Ash-free Extreme Pressure Anti-wear Additive
Product Description
BSD-3918 is a light yellow transparent liquid formulated as a phosphorus-nitrogen (P-N) based ash-free additive, synthesized from phosphate ester and long-chain fatty amine. It delivers multifunctional performance, including extreme pressure (EP), anti-wear (AW), anti-rust, and friction-modifying properties, making it ideal for a wide range of lubricant applications.
Key Features & Benefits
- Extreme Pressure & Anti-Wear Performance – Enhances load-carrying capacity and reduces wear in high-stress conditions.
- Friction Modifier – Improves lubricity and energy efficiency.
- Synergistic with Sulfur-Based Additives – Boosts EP/AW performance when combined with sulfur-containing agents.
- Excellent Oil Solubility – Compatible with mineral oils, PAO, and ester-based lubricants.
- Ash-Free Formulation – Prevents deposits, extending equipment life and maintaining cleanliness.
- Anti-Rust Protection– Protects metal surfaces from corrosion.
Applications & Recommended Dosage
| Application | Dosage Range | Key Benefit |
| Gear Oils (Vehicle & Industrial) | 0.2–1.0% | Improves FZG gear test performance, wear protection |
| Lubricating Greases | 0.5–1.0% | Enhances EP/AW properties in grease formulations |
| Hydraulic Oils | 0.2–0.5% | Reduces pump wear, extends fluid life |
Technical Advantages & Parameters
- Improves FZG Test Performance – Reliable for gear protection under high loads.
- Versatile Base Oil Compatibility – Works in mineral oils, synthetic PAOs, and esters.
- Synergistic with Sulfur Additives – Enhances extreme pressure performance in formulated lubricants.
