Dithiophosphates are a type of organophosphorus compound widely used as multifunctional additives in lubricating oils and metalworking fluids. These additives offer various benefits to enhance the performance and longevity of lubricants, especially in demanding applications such as automotive engines, industrial machinery, and metalworking operations.
Anti-Wear Additives in Lubricants:
Zinc dithiophosphate (ZDDP) is mainly used as a lubricant additive. A specific type of dithiophosphate, often referred to as zinc dithiophosphate (ZDDP), is a major component in many anti-wear additives used in lubricating oils.
In this application, ZDDP forms a protective layer on metal surfaces, reducing friction and wear between contacting parts, especially under high pressure and load conditions.
ZDDP is commonly found in engine oils, industrial lubricants, automatic transmission fluids (ATFs), and gear oils.
Dithiophosphates in Metalworking Fluids：
In metalworking applications, dithiophosphates are used as corrosion inhibitors and lubricants in cutting and grinding fluids. These compounds form a protective film on metal surfaces, preventing corrosion and wear during machining operations. This not only extends the lifespan of tools and equipment but also improves the quality of the finished product.
They help improve the performance, durability and reliability of lubricated components by reducing wear, preventing oxidation and corrosion, and enhancing extreme pressure performance.
