Usage:

In Dimercapto-1,3,4-Thiadiazole dimer molecular structure,there is -C -N- S constituent thiadiazole ester heterocyclic and S--S Al sulphur keys so that it can have a conjugate effect on metallic ion especially copper metal ions and can complexation with metal ions to form metal protective film attached on the surface of metal to support Extreme pressure and anti-wear properties to metal.


Dimercapto-1,3,4-Thiadiazole dimer mainly used in producing the extrusion anti-wear additive in lubricating grease,high temperature resistant extreme pressure and anti-wear additive.


Package:25kg/barrel
