Abstract: Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance. It has now been found by using small amounts of either ammonium dithiocarbamate or zinc dithiocarbamate in combination with the antimony dithiocarbamate (SbDTC), a lower amount of SbDTC can be used in the lubricating composition while still maintaining excellent or exceptional EP protection. To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.
