Extreme Pressure Antiwear Additive

Extreme Pressure Antiwear Additive

Advanced Solutions for Maximum Load Protection and Surface Preservation

Premium Extreme Pressure Lubricant Additives

Extreme Pressure (EP) Additives In Lubricants Are Critical Components That Prevent Metal Wear And Sintering By Forming Chemical Reaction Films To Separate Metal Surfaces. These extreme pressure lubricant additives provide essential functions including:

  • Extreme Pressure Protection: Enhanced Load-Carrying Capacity
  • Anti-Micropitting: Reduced Surface Roughness
  • Thermal Stability: Instantaneous High-Temperature Resistance
  • Synergistic Lubrication: Forms Complementary Protective Layers When Combined With Sulfur-Phosphorus Anti-Wear Additives

Our advanced extreme pressure lubricant solutions are engineered for maximum protection in the most demanding industrial environments.
