Product Description

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
