Lubricating oils and greases under oxidizing conditions yield unstable materials called peroxides which quickly decompose to form other materials which are even more susceptible to oxidation. This process is like a chain reaction which is accelerated by increased temperatures and further catalyzed by metals present in the formulations.
This product is a crystalline antioxidant that the field of application of this universal oxidation inhibitor includes most types of lubricants. Limitations are given by the long-term oil temperature which should not exceed 90C in open and 120C in closed systems.
