ADDITIN® RC 2540

Highly active, low viscosity, light colored sulfur carrier

Additin® RC 2540 is a highly active, light-colored, and nearly odorless sulfur carrier that is well soluble in most types of base oils. Due to its extremely high sulfur activity, it is an excellent choice for manufacturing metalworking fluids suitable for a wide range of heavy-duty metal removal and metal forming processes. It is also an outstanding replacement for chlorinated paraffins.

Additin® RC 2540 shows significant sulfur activity even at moderately elevated temperatures of 50 to 60°C (122 to 140°F). As the temperature increases, it provides a steadily increasing active sulfur level, reaching up to 90% of its total sulfur content at 150°C (302°F). Because of its high sulfur content, Additin® RC 2540 can be used in combination with other sulfur carriers to enhance their extreme pressure (EP) activity.

The performance of metalworking oils containing Additin® RC 2540 can be further improved by synergistic combinations with overbased sulfonates like Calcinate® OR or by polar compounds like Additin® RC 8000 or Additin® RC 8100. Zinc dithiophosphates, such as Additin® RC 3038, phosphoric acid partial esters like Additin® RC 3760, or ashless phosphorus-sulfur additives such as Additin® RC 3890 are also excellent complements to Additin® RC 2540. Additin® RC 2540 is easily emulsifiable and performs effectively as an EP booster for soluble oils and semisynthetic metalworking fluid emulsions.
