Industrial Lubricant ZDDP Additive Anti Wear and Corrosion
Zinc Alkyl Dithiophosphate (ZDDP) is a versatile antioxidant corrosion inhibitor additive for lubricants. This formulation appears as a light yellow, clear liquid with a distinctive sulfur and phosphorus odor. The primary active component, zinc dialkyldithiophosphate, is present at 90-95% concentration.

Performance Characteristics
- Extreme Pressure & Anti-Wear Protection: Under high temperature/pressure conditions, ZDDP decomposes on contact surfaces to form a protective film that minimizes metal-to-metal contact, reducing wear in engines, gearboxes, and transmission systems.
- Oxidation Inhibition: Effectively traps free radicals to prevent chain reactions, slowing oil degradation while inhibiting sludge and carbon deposit formation for cleaner lubrication systems and extended oil change intervals.
- Corrosion Prevention: Provides effective protection for non-ferrous metals (copper, lead, babbitt alloys) by neutralizing acidic compounds formed during oil operation.
Primary Applications
Widely used in motor oils, hydraulic fluids, transmission lubricants, and various industrial/automotive lubricant formulations.
Key Advantages
- Multi-functional protection combining extreme pressure anti-wear, antioxidant, and anti-rust properties
- Proven technology with excellent cost efficiency and long-term reliability
- Industry-standard additive with demonstrated performance across applications
