DC-440

Methylene bis dibutyl dithiocarbamate

Antiwear, EP and antioxidant performance with no metal, no phosphorus and no ash. This single grade is the most direct answer to the low-SAPS problem in this catalogue, and it is equally at home replacing lead or zinc in a grease.

Cross-reference

Grades a formulator would benchmark DC-440 against. Naming them is not a claim of equivalence — it is where to start the comparison.

The chemistry

Ashless Dithiocarbamates

Multifunctional antiwear / antioxidant, zero ash

Typical treat rate0.2 – 1.5 %

Methylene bis dibutyl dithiocarbamate delivers antiwear, extreme-pressure and antioxidant performance without contributing metal, phosphorus or sulphated ash. That combination is exactly what the low-SAPS trend and aftertreatment-compatibility requirements have made valuable.
