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

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.

Regulatory & Environmental

• Ash-free (No metallic components, low residue)
• Suitable for environmentally sensitive applications where traditional sulfur/chlorine additives are restricted.
