Product Overview

NT3852 is a multifunctional, low-ash lubricant additive belonging to the class of liquid antimony dialkyl dithiocarbamate (SbDTC). It is one of the most widely used and comprehensively performing products among carbamate‑based additives. This product exhibits outstanding extreme‑pressure performance and excellent anti‑wear properties, while also offering superior oxidation stability and metal deactivating capabilities, thereby effectively extending the service life and enhancing the stability of lubricants. Additionally, it demonstrates excellent oil solubility, dissolving rapidly in both mineral and synthetic oils, and displays favorable synergistic compatibility with a wide range of common additives. Consequently, it is extensively employed in engine oils, gear oils, compressor oils, industrial lubricants, synthetic lubricants, and various greases.  

 

Performance Features

① Outstanding extreme-pressure performance: Under heavy loads, it effectively prevents metal surfaces from welding together, providing reliable extreme-pressure protection for equipment.

② Outstanding wear resistance: Forms a chemical protective film on the friction surface, reducing friction and wear and extending equipment service life.

③ Excellent antioxidant performance: Effectively inhibits oxidation and degradation of the oil at high temperatures, reduces sludge and deposit formation, and extends oil-change intervals.

④ Excellent oil solubility: rapidly dissolves in both mineral and synthetic oils and exhibits high compatibility in composite formulations.

⑤ Broad compatibility and synergy: Exhibits excellent compatibility with a wide range of commonly used additives, delivering significant synergistic enhancement when compounded, and demonstrating outstanding formulation stability.

 

Scope of Application

① Industrial lubricants: gear oils, hydraulic oils, compressor oils, and turbine oils.
② Automotive lubricants: engine oil, gear oil, and transmission fluid.
③ Greases: Various types of greases, including industrial and automotive grades.
④ Specialty lubricants: synthetic lubricants, marine oils, and oils for stationary diesel engines.
