MD-300

Benzotriazole derivative

High-nitrogen triazole. Treats at hundredths of a percent, which makes it one of the cheapest insurance policies in a formulation against copper-catalysed oxidation.

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.
