Benzotriazole derivatives CAS:15497-45-7

What is CSAIL T551？

CSAIL T551 is an oil‑soluble benzotriazole‑derived metal deactivator. It can form inert protective films on metal surfaces or generate chelate compounds with metal ions to restrain metal‑ion‑catalyzed oil oxidation. It delivers prominent synergistic antioxidation effect when compounded with antioxidants such as T501, improves the antioxidative capacity of lubricants and extends oil service life. This additive can be directly dosed into lubricant formulations. Compatibility test shall be performed prior to formal blending.

Standard packaging adopts 50 kg plastic drums and 180 kg steel drums, which need to be stored in cool, dry and well‑ventilated warehouses.

Features of CSAIL T551

• Excellent antioxidation performance Effectively suppress the catalytic oxidation triggered by metal ions in lubricant systems.

• Superior copper corrosion inhibition Provide reliable corrosion protection for copper‑based metal components.

• Low‑dosage performance Achieve expected protective effect under low treat concentration.

• Good synergistic compatibility with antioxidants Obvious synergistic effect when used together with antioxidants like T501 to enhance overall oil stability.

Functions of CSAIL T551

• Metal passivation & chelation: Form inert films on metal surfaces or produce chelate compounds with metal ions to block catalytic oxidation sources.

• Copper corrosion inhibition: Mitigate copper corrosion within lubricating oil and grease systems.

• Antioxidant synergism: Cooperate with common antioxidants to boost antioxidative property and prolong oil service life.

• Formulation compatibility: Can be directly added into lubricant systems; pre‑blending compatibility test is mandatory to guarantee finished‑product performance.
