Stability of lubricant against thermal stress is a key issue for the fact that oxygen and oxidation accelerating chemicals which develop decomposition of lubricants. Acids generated through oxidation of lubricants may significantly increase the corrosion rate of metallic surfaces. Antioxidants, both aminic and phenolic types, prevent oxidation reaction from happening and will also enhance the life of lubricant. Aaminic antioxidants are highly recommended versus phenolic type at high temperature conditions. For further information please contact our company.
