NA-LUBE® AO Primary Antioxidants
The NA-LUBE AO product line is a series of phenolic and aminic antioxidants that is used in a broad range of industrial lubricants, engine oils, and greases. These products retard the oxidation of lubricants thereby reducing sludge formation and viscosity increase, providing economic and ecological benefits. The NA-LUBE antioxidants exhibit the following physical and performance properties:
- Ashless
- Non-corrosive
- Excellent solubility in a wide range of base fluids
- Enhanced thermal and oxidative stability
Both solid and liquid NA-LUBE AO products are available to offer maximum formulating flexibility.
