Description

Potassium O,o-Dibutyl Dithiophosphate is an organophosphorus compound widely utilized as a high-performance additive and intermediate. Its primary value lies in its excellent properties as an extreme pressure (EP) agent, anti-wear additive, and corrosion inhibitor. This chemical is essential for manufacturers in the lubricant, metalworking fluid, and mining industries, where it enhances the performance and longevity of functional fluids under severe operating conditions.

Application

• As a key extreme pressure (EP) and anti-wear additive in industrial lubricants and gear oils.
• As a corrosion inhibitor and friction modifier in advanced metalworking fluids and hydraulic fluids.
• As a collector and frother in the flotation process for sulfide ores in the mining industry.
• As a stabilizer and antioxidant in certain polymer and rubber formulations.
• As a chemical intermediate for the synthesis of other specialized organophosphorus compounds.
• As an additive in grease formulations to improve load-carrying capacity.
