Description

Zinc Bis[Bis(Dodecylphenyl)] Bis(Dithiophosphate) CAS NO 54261-67-5 is a high-performance organometallic compound widely used as an extreme pressure (EP) additive and anti-wear agent. This chemical is critical for enhancing the durability and operational lifespan of industrial lubricants and metalworking fluids under severe conditions. It is primarily needed by formulators and manufacturers in the lubricant, grease, and metal processing industries seeking to improve equipment protection and performance.

Application

• Primary extreme pressure (EP) additive in industrial gear oils and transmission fluids.
• Key anti-wear agent in hydraulic fluids and compressor oils to reduce friction and surface fatigue.
• Performance-enhancing component in metalworking fluids for cutting, grinding, and forming operations.
• Additive in grease formulations to provide load-carrying capacity and prevent scoring.
• Used in specialized lubricant packages for heavy-duty mining and construction equipment.
• Component in some corrosion inhibitor blends for ferrous metals.

Quality Control

Our Zinc Bis[Bis(Dodecylphenyl)] Bis(Dithiophosphate) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested for critical parameters including zinc content, phosphorus content, sulfur content, and viscosity to meet industry specifications. A Certificate of Analysis (COA) documenting these results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizers. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize exposure to moisture and air.
