ZDDP (Zinc Dialkyldithiophosphate)

Multi-Functional Performance Additives for Lubricants

Zinc Dialkyldithiophosphate (ZDDP) additives are essential components in modern lubricant formulations. Known for their oxidation inhibition, anti-wear protection, and extreme pressure (EP) performance, ZDDPs are widely used in engine oils, greases, and hydraulic fluids. They enhance the operational life of machinery and engines by forming protective films on metal surfaces, minimizing wear, and resisting oxidation under high thermal stress.

Product Portfolio

A. ZDDP Additive – Type A

Application: Ideal for engine oils, greases, and hydraulic oils, this ZDDP provides enhanced oxidation resistance and anti-wear performance in demanding environments. Suitable for high-performance lubricants.

Recommended Dosage: Typically used at 0.1% to 2% by weight, depending on base oil characteristics, compatibility with other additives, and targeted lubricant performance.

Blending Temperature: Maximum: 90°C

Storage Stability: Stable for at least 1 year under proper storage conditions.

B. ZDDP Additive – Type B (High Sulfur Content)

Application: Designed for use in engine oils, hydraulic oils, and greases, this ZDDP variant contains a higher sulfur content, making it especially effective in extreme pressure (EP) and anti-wear applications.

Sulfur Content: Approx. 16% by weight (AAS verified)

Recommended Dosage: 1% to 10% by weight, based on EP demands, base oil compatibility, and application-specific requirements.

Blending Temperature: Maximum: 60°C

Storage Stability: Retains stability for 1 year when stored properly.

C. ZDDP Additive – Type C (Multi-Effect Performance)

Application: A multi-functional ZDDP additive for a wide range of lubricants, excluding formulations intended for silver-containing components. Offers a balanced combination of anti-oxidation, anti-wear, anti-corrosion, and extreme pressure protection.

Appearance: Amber transparent liquid, allowing for easy blending and visual quality control.

Recommended Dosage: 0.5% to 3.0% by weight, adjusted according to formulation goals.

Performance Highlights:

  • Oxidation Stability: Prevents oil degradation and sludge formation.
  • Corrosion Protection: Safeguards metal surfaces from rust and oxidation.
  • Anti-Wear: Forms protective films under boundary lubrication.
  • Extreme Pressure Resistance: Withstands high load conditions.
  • Thermal Stability: Maintains performance at elevated temperatures.
  • Hydrolytic Stability: Resists water-induced breakdown, extending oil life.

Key Benefits of ZDDP Additives

Applications at a Glance

  • Engine Oils – Automotive, motorcycle, heavy-duty diesel
