Ashless Dialkyldithiocarbamate Ester
Ashless dialkyldithiocarbamate ester — a metal-free, ashless anti-wear and antioxidant additive that delivers multifunctional protection without zinc, phosphorus or ash.
The metal-free multifunctional anti-wear additive
Dithiocarbamate ester chemistry, made ashless, delivers both anti-wear and antioxidant performance without any zinc, phosphorus or ash — ideal for the cleanest low-SAPS oils.
Ashless dialkyldithiocarbamate ester is a metal-free, ashless additive providing both anti-wear and antioxidant performance. The dithiocarbamate ester structure forms protective films at metal contacts and scavenges oxidation radicals, all without contributing zinc, phosphorus or sulphated ash. This makes it especially valuable in the cleanest low-SAPS engine oils, turbine oils and industrial lubricants seeking multifunctional protection while minimizing ash, phosphorus and metal. It is part of the anti-wear agents range and complements or partially replaces ZDDP in modern formulations.
