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.
