Phosphate Amine Salt

Phosphate Amine Salt EP/AW Additives are oil‑soluble lubricant additives manufactured by Fanschem. Including long‑chain alkyl phosphate amine salts, branched‑chain modified grades and low‑irritation eco‑friendly variants, these liquid‑based additives form durable boundary tribofilms on contacting metal surfaces under heavy‑duty extreme‑pressure working conditions, cut interfacial friction and protect metal parts against scoring, metal adhesion and abrasive deterioration. They feature satisfactory high‑temperature thermal stability, restrained corrosive effect on non‑ferrous metals and outstanding compatibility with thiadiazole corrosion inhibitors, organic‑molybdenum friction modifiers and multiple kinds of common lubricant additives. Widely adopted in metal‑working fluids, automotive gear oils, industrial circulating oils, hydraulic fluids and heavy‑equipment greases, Fanschem supplies tailor‑made grades to satisfy global industrial‑lubricant specifications and environmental‑protection criteria, offering steady bulk‑volume supply and professional formulation‑adjustment technical service for lubricant manufacturers worldwide.

What Are Phosphate Amine Salt EP/AW Additives?

Phosphate Amine Salt EP/AW Additives belong to multi‑functional ash‑free lubricant additives synthesised through the neutralisation reaction between alkyl phosphate and organic amine. They are engineered to deliver comprehensive extreme‑pressure, anti‑wear and rust‑resistant protection under boundary‑lubrication and heavy‑duty operating environments. Unlike ordinary phosphate‑ester additives with single‑dimensional tribological property, the complete Fanschem phosphate amine‑salt product lineup covers PSAIL 3490, PSAIL 3740(T308), PSAIL 3741, PSAIL 2280, PSAIL 3880 and PSAIL T307S. When heavy contact pressure and frictional heat occur on metal contact surfaces, the additive molecules break down and adsorb tightly onto ferrous and non‑ferrous metal substrates, constructing a sturdy phosphorus‑nitrogen‑containing protective tribofilm. This surface‑shielding layer can separate metal‑to‑metal contact, lower friction coefficient, restrain abrasive scratch, metal adhesion and seizure. Thanks to its integrated rust‑inhibition characteristic and favourable solubility in different base oils, phosphate amine‑salt additives are widely favoured by international lubricant formulators for metal‑working fluids, gear lubricants and circulating industrial‑oil formulations.

Core Performance & Key Features of Phosphate Amine Salt EP/AW Additives

Multi‑functional EP & Anti‑Wear Comprehensive Performance

Every grade of Fanschem phosphate amine‑salt additive possesses dependable load‑bearing capacity under shock‑load, high‑speed and harsh working circumstances. The phosphorus‑nitrogen composite tribofilm maintains stable structure at elevated contact temperature, effectively reducing the wear loss of gear teeth, sliding bearings, hydraulic components and machined work‑pieces. It can relieve adhesive wear, surface pitting and metal welding‑up which are easily triggered when the boundary lubricating film collapses during peak‑load operation.

Ashless Formula & Excellent Anti‑Rust Synergy

The whole series adopts ash‑free molecular framework and will not produce metallic ash deposit after base‑oil decomposition, complying with current‑day low‑ash, eco‑friendly lubricant specifications. Benefiting from the organic‑amine composition inside molecular structure, these additives carry intrinsic rust and corrosion inhibition capacity for ferrous metal. When matched with other anti‑oxidants and metal passivating agents, obvious synergistic effects can be achieved. All six product variants are homogeneous transparent liquid with outstanding miscibility with mineral oil, synthetic ester and PAO base stocks. No sediment will be generated after long‑term storage under low‑temperature surroundings.

Technical Advantages Over Conventional Phosphate EP Additives

Compared with common phosphate‑ester extreme‑pressure additives, Fanschem phosphate amine‑salt EP/AW additives own many competitive technical merits. The phosphorus‑nitrogen composite film delivers better adhesive force against metal surfaces, so its anti‑wear performance stays excellent under repeated impact load. Built‑in amine groups endow the additive with rust‑preventing capability, helping lubricant producers cut down the dosage of separate rust inhibitor. These liquid additives exert mild corrosion towards copper and yellow‑metal spare‑parts and seldom bring about metal discoloration. They feature outstanding compatibility with organic‑molybdenum friction modifiers, sulphur‑based extreme‑pressure agents and dispersants without chemical incompatibility. Less acidic harmful by‑products will be generated in the course of long‑time service. Moreover, its effective additive dosage is moderate, which helps lubricant blenders optimise raw‑material expenditure.

Main Applications of Phosphate Amine Salt Lubricant Additives

Fanschem phosphate amine‑salt extreme‑pressure additives are adaptable to multiple categories of industrial and mechanical lubrication systems. They serve as key functional additives for heavy‑duty industrial gear oil and manual transmission oil to protect gear surfaces from friction damage. In the field of metal processing, they are widely incorporated into cutting fluid, drawing lubricant, stamping and forming oil for ferrous‑metal machining. These multi‑purpose additives are also suitable for high‑pressure hydraulic oil, compressor circulating oil and multi‑purpose industrial grease. In addition, they fit low‑phosphorus low‑SAPS environmental‑friendly lubricant formulas and the lubrication system of construction, mining and agricultural heavy‑duty machinery.

Technical Specifications & Product Parameters

Fanschem supplies six mature industrial‑grade phosphate amine‑salt EP/AW additives with adjustable physicochemical indicators for personalised formula requirements. PSAIL 3490 is hexyl phosphate amine‑salt with balanced extreme‑pressure and anti‑rust property, well‑suited for common‑purpose metal‑working fluids. PSAIL 3740(T308), butyl phosphate amine salt, boasts prominent bearing capacity and is commonly used within heavy‑load gear‑oil packages. PSAIL 3741 possesses improved high‑temperature stability for long‑service‑life circulating oil. PSAIL 2280 features low‑temperature fluidity and adapts to machinery working in cold‑temperature environments. PSAIL 3880 delivers excellent synergistic effect when compounded with sulphur‑containing additives. PSAIL T307S is a complex thiophosphate amine‑salt variant with comprehensive tribological performance. Buyers are allowed to custom‑tune phosphorus content, kinematic viscosity, flash‑point and other essential technical parameters.
