Anti-Wear Agents
Sulfurized Olefin Extreme Pressure Additive
Sulfurized olefins are reactive sulfur-containing extreme pressure (EP) additives produced by the reaction of olefins with elemental sulfur or sulfur chlorides. They form iron sulfide protective films at asperity contact points under high-load gear and bearing contacts, preventing scuffing and welding. Available in active and inactive sulfur variants, they are core components in GL-4/GL-5 gear oils and heavy-duty industrial lubricants.

Tolyltriazole (TTA) Metal Deactivator for Lubricants
Tolyltriazole (TTA) is a heterocyclic metal deactivator and corrosion inhibitor widely used in lubricants, coolants, and fuels to protect copper, brass, bronze, and other non-ferrous metals. TTA forms a stable protective coordination complex on copper surfaces, blocking oxidative attack and preventing catalytic pro-oxidation by dissolved copper ions. It is an essential component in engine oils, hydraulic fluids, automatic transmission fluids, and water-based metalworking fluids containing mixed metal components.

Tricresyl Phosphate (TCP) EP/Antiwear Additive
Tricresyl phosphate (TCP) is a well-established aryl phosphate ester used as an extreme pressure and antiwear additive in aviation turbine oils, industrial gear oils, and high-performance automotive lubricants. It forms a tenacious iron phosphate tribofilm at elevated temperatures that protects against scuffing under shock loading. TCP is the benchmark antiwear additive in aviation turbine oils certified to MIL-PRF-23699 and DEF STAN 91-097.

Triphenyl Phosphate (TPP) EP Additive
Triphenyl phosphate (TPP) is an aryl phosphate ester that functions as an antiwear and mild extreme-pressure additive in lubricants and hydraulic fluids. It forms a thin iron phosphate layer on metal surfaces at elevated temperatures, protecting against abrasive wear. TPP also provides excellent fire-resistant properties and is used in turbine oils, compressor lubricants, and phosphate ester-based hydraulic fluids where both lubricity and fire resistance are needed.

Two-Stroke Engine Oil Additive Package
Two-stroke engine oil additive packages are specially formulated for air-cooled and water-cooled two-stroke gasoline engines, providing excellent lubrication, deposit control, and combustion cleanliness in the demanding pre-mix and injection lubrication modes. These packages are formulated to meet JASO FC/FD standards for smoke reduction and ring-sticking prevention. They combine ashless detergents, dispersants, antioxidants, and lubricity additives compatible with fuel-mixed delivery systems.

Zinc Dialkyldithiophosphate (ZDDP)
Zinc dialkyldithiophosphate (ZDDP) is the cornerstone multifunctional additive in engine oil formulations, delivering simultaneous antiwear, extreme-pressure, and antioxidant performance. It forms a protective tribofilm on metal surfaces under boundary lubrication conditions, dramatically extending component life. Widely specified in API SN/SP, ACEA A3/B4, and OEM-approved passenger car and heavy-duty engine oil packages.
