ANTIOXIDANTS
ANTIOXIDANTS
Our range of antioxidants includes aminic and phenolic antioxidants that enable formulators to produce high quality lubricants.
Antioxidants are a selected group of chemicals that can be used to stop or reduce the rate of oxidation in the formulation of lubricants. Pending on the mode of action, three categories of antioxidants are as follows: Primary antioxidants (radical scavengers), secondary antioxidants (peroxide decomposers) and metal deactivators (complex-forming or chelating agents).
Selection of the antioxidants in a formulation is a critical decision that depends on the base oil, application and other ingredients in the formulations.
