MD-110

C12 thiadiazole derivative (DMTD)

The C12 chain gives the best oil solubility of the DMTD range. This is the grade for fully formulated synthetic fluids where the shorter-chain versions will haze or drop out over shelf life.

Cross-reference

Grades a formulator would benchmark MD-110 against. Naming them is not a claim of equivalence — it is where to start the comparison.

The chemistry

Yellow Metal Deactivators

Copper passivation and catalytic-oxidation suppression

Typical treat rate0.02 – 0.5 %

Triazoles and thiadiazoles chelate onto copper and its alloys. Two jobs at once: they stop the metal from being attacked, and they stop dissolved copper ions from catalysing oxidation of the base oil. In a turbine or gear oil, omitting these is how you get a fluid that fails oxidation testing for reasons nobody can explain.

Documentation

A full technical data sheet, safety data sheet in the language of the receiving country, REACH status statement and SVHC declaration are issued with every enquiry for MD-110. Certificates of analysis accompany each consignment and retained samples are held for the full shelf life.
