T551 lubricant Metal Deactivator additive
Benzotriazole Derivative


T551 lubricant Metal DeactivatorDescription 
T551 is a light yellow transparent liquid. It has a prominent synergistic effect on inhibiting the catalytic effect of metal ions on oil oxidation, improving the oxidation resistance of oil products, and prolonging the service life of oil products. It can form an inert film on the metal surface or form a chelate with metal ions to prevent Oxidation of metal has the catalytic acceleration effect of inhibiting the oxidation reaction of the metal, and exhibits an excellent synergistic effect with BHT in an appropriate amount, thereby greatly reducing the amount of BHT. Avoid using this product in combination with ZDDP during use, otherwise precipitation will occur. It is mainly used in industrial lubricating oils such as turbine oil, oil film bearing oil, industrial gear oil, transformer oil and circulating oil. It is a high-performance and high-performance additive.
