Thiadiazole tert-dodecyl mercaptan condensate CAS: 59656-20-1

What is CSAIL T561？

CSAIL T561 is an oil‑soluble liquid sulfur‑based metal deactivator developed by FansChem, with core active component didodecyl disulfide. It features low‑odour property, can effectively suppress corrosive attack from active sulfur and delivers prominent synergistic antioxidation performance with antioxidants. This additive can be directly dosed into lubricant formulations and is widely applicable to various automotive lubricating greases, industrial lubricating oils & greases and metalworking fluids. Compatibility test shall be performed prior to formal blending.

Standard packaging adopts 50 kg plastic drums and 200 kg steel drums, which need to be stored in cool, dry and well‑ventilated warehouses.

Features of CSAIL T561

• Low treat dosage & excellent oil‑solubility Good miscibility with lubricant base stocks, can be directly incorporated into finished formulations.

• Low‑odour performance Low‑odour characteristic improves on‑site operating experience during batching.

• Superior active‑sulfur corrosion inhibition Effectively restrain corrosion triggered by active sulfur inside lubricant systems.

• Strong antioxidant synergistic performance Produce obvious synergistic effect together with various antioxidants to slow down oil degradation.

• Convenient feeding operation Direct addition into formula system; only lab compatibility test is needed before formal production.

Functions of CSAIL T561

• Active‑sulfur corrosion suppression: Inhibit metal corrosion caused by active sulfur in lubricant systems, protect metal components.

• Antioxidant synergism: Work together with different antioxidants to retard oxidative deterioration of lubricants.

• Formulation compatibility: Good oil‑solubility for lubricant systems; pre‑blending compatibility test is mandatory to guarantee finished‑product performance.
