Description

Zinc Dithiophosphate is an organophosphorus compound widely recognized for its exceptional anti-wear and extreme pressure (EP) properties. This makes it a critical performance additive in industrial lubricants and functional fluids, where it protects metal surfaces under high-stress conditions. Industries such as automotive, metalworking, and heavy machinery manufacturing rely on this additive to enhance equipment longevity and operational efficiency.

Application

• Primary anti-wear and extreme pressure (EP) additive in engine oils, gear oils, and hydraulic fluids.
• Key component in metalworking fluids and industrial lubricants for machining and forming operations.
• Additive in greases to provide enhanced load-carrying capacity and corrosion inhibition.
• Used in compressor oils and other specialty industrial lubricants requiring oxidation stability.
• Acts as a multifunctional additive, offering antioxidant and anti-corrosion benefits alongside its primary anti-wear function.

Quality Control

Our Zinc Dithiophosphate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance reliability. Production adheres to relevant industry standards for lubricant additives. Comprehensive testing, including analysis of zinc content, phosphorus content, and sulfur content, is performed. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its nature as an easily oxidized substance, it is recommended to store under an inert atmosphere such as nitrogen for long-term preservation. Keep container tightly sealed when not in use to minimize moisture absorption and oxidation.
