Product Applications
  • Water miscible metalworking fluids
  • Neat metalworking fluids
  • The use of Additin® RC 2540 is a good alternative to the sulfurization of base oils with elementary sulfur. In addition, Additin® RC 2540 shows with increasing temperatures a steadily increasing active sulfur level (up to max. 38 %) resulting in an effective EP activity at only slightly elevated temperatures (50 to 60°C).
  • Additin® RC 2540 can be successfully combined with other sulfur carriers such as Additin RC 2415 in order to increase EP activity.
  • The antiwear effect is improved by combination of Additin® RC 2540 with zinc dithiophosphates, e.g. Additin® RC 3038, phosphoric acid partial esters or ashless phosphorus-sulfur additives e.g.Additin® RC 3880
