ANTI-OXIDANTS

Enhancing Lubricant Stability and Extending Equipment Life
Oxidation is one of the primary causes of lubricant degradation. It leads to increased viscosity, acid formation, sludge, and varnish buildup, ultimately reducing the performance and lifespan of both the lubricant and the equipment it protects. Antioxidants are vital additives that inhibit these oxidation processes, ensuring lubricant stability during extended use and under high-temperature conditions. Our line of aminic antioxidants offers reliable protection against thermal and oxidative degradation in a wide range of lubricant applications.

Key Functions of Antioxidants in Lubricants

  • 🛡️ Oxidation Inhibition: Prevents the formation of acids and sludge that degrade lubricants.
  • 🛠️ Viscosity Control: Maintains consistent oil viscosity over time, even under thermal stress.
  • 🧪 Improved Lubricant Life: Extends the usable life of the lubricant and protects system components.
  • 🔄 Synergistic Performance: Works effectively with other additive systems like anti-wear, detergents, and dispersants.
  • 🌍 Application Versatility: Suitable for automotive, industrial, hydraulic, and gear oil formulations.
