1. DESCRIPTION
The product is a transparent liquid, prepared from 2, 5-dimercaptothiodiazole and thioalcohol. It provides the lubricant with preferable antiwear, anti-oxidation, anti-corrosion and metal deactivation performance.
2. APPLICATIONS
It is used primarily for anti-wear hydraulic oil, low-temperature hydraulic oil, turbine oil and gasoline engine oil, serves as anti-corrosion agent, antiwear agent and metal deactivator; used as extreme pressure agent, bacteria and oxidation inhibitor in emulsion; and antioxidant in internal combustion engine oil.
The dosage is from 0.3% to 0.4%.

3. CHARACTERISTICS
Excellent performance of anti-oxidation and copper corrosion inhibition
In hydraulic oil, it can significantly reduce the copper corrosion from ZDDP and settle hydrolytic stability.
In internal combustion engine oil, it can improve the anti-oxidation ability of paraffinic oil.
