Amine dialkyldithiophosphate CAS:71888-91-0

What is Amine Dialkyldithiophosphate PSAIL 3880?

Amine Dialkyldithiophosphate PSAIL 3880 is a high‑performance ashless antiwear additive developed for modern industrial lubricant formulas. Its chemical name is amine dialkyldithiophosphate (CAS No.: 71888‑91‑0), and it acts as an advanced alternative to zinc dialkyldithiophosphate (ZDDP) for applications requiring metal‑free packages. This additive is specially developed to meet environmental and regulatory requirements restricting zinc and other heavy metals, while offering strong protection under severe working conditions. Its molecular structure contains phosphorus, sulfur segments and organic amine groups, granting good thermal stability and compatibility with many base oils and additive systems.

Features of Amine Dialkyldithiophosphate PSAIL 3880

• Ashless & metal‑free property: As an ashless additive, it avoids ash accumulation that harms machine efficiency, supporting cleaner operation and longer equipment service life.

• Excellent oxidation resistance: It possesses remarkable oxidation resistance, greatly slowing oil deterioration at high temperatures and cutting sludge generation.

• Direct ZDDP replacement: Being inherently metal‑free, it works as a flexible direct replacement for ZDDP in formulas where zinc is forbidden or unwanted.

• Good synergy with sulfur‑containing additives: Besides, it shows excellent synergism with sulfur‑containing additives, boosting overall tribological performance without creating corrosive by‑products.

• Hydrolytic stability & low foaming tendency: Its multi‑purpose structure also delivers good hydrolytic stability and low foaming tendency, giving formulators a dependable and easy‑to‑use option for sophisticated industrial lubricant systems.

Functions of Amine Dialkyldithiophosphate PSAIL 3880

• Anti‑wear & extreme‑pressure protection: As an antiwear agent, it builds a robust tribofilm on metal surfaces to reduce friction and stop scuffing, scoring and micropitting under high‑pressure contact. Moreover, this additive improves extreme‑pressure (EP) performance for gear oils and greases, delivering stable protection under shock loads while keeping good compatibility with elastomers and seals.

• Oxidation suppression: Its antioxidant capability interrupts free‑radical chain reactions, maintaining base oil integrity and viscosity stability even under long‑term thermal load.

• Workpiece surface improvement: In metalworking systems, when blended with sulfur donors, it helps improve workpiece surface quality through controlled chemical polishing and reduces built‑up edge formation. Such synergistic effect can increase tool life by up to 30% according to field trials by lowering abrasive wear and thermal cracking.

Applications of Amine Dialkyldithiophosphate PSAIL 3880

Metalworking fluids

Within metalworking fluids, it is essential for precision processes including broaching, deep‑hole drilling and high‑speed machining to improve surface finish and tool durability. It acts as a vital ingredient in specialty oils such as cutting fluids, grinding coolants and honing oils, especially for difficult‑to‑machine alloys.

Zinc‑free industrial oils

Outside metalworking, this additive is widely used in zinc‑free industrial oils, covering hydraulic fluids (ISO VG 32–68), industrial gear oils (AGMA 4–8 EP) and compressor oils. Its ashless characteristic prevents valve and filter blockages.

Industrial greases

It can also upgrade grease performance for mining and construction machinery, offering wear protection in centralized lubrication circuits.

Custom formulation

For flexible formulation design, it can be combined with associated products like RC 3880 to customize solutions for industry‑specific challenges, covering auto manufacturing, aerospace part processing and heavy‑duty machinery operations.
