ADDITIN® RC 2516
High viscosity, high lubricity, medium active sulfur carrier with improved solubility
Additin® RC 2516 is a deactivated, medium active,
light colored, low odor, high viscosity sulfur carrier with good solubility
even in nonpolar base oils. Due to its excellent polarity and lubricity in
combination with a controlled sulfur activity, it is particularly suited for
manufacturing metalworking fluids for medium to heavy duty stamping, fine
blanking and metal forming processes. The low copper corrosivity makes it also
suitable for machining yellow metal alloys.
It is also highly recommended for the formulation of EP greases, slideway oils and industrial gear oils. In order to improve the overall performance of the EP grease or slideway oil formulation the addition of antioxidants such as Additin RC 7110® and/or Additin® RC 7135 with anticorrosion additives, e.g. Additin® RC 4220, is recommended.
The
performance of metalworking fluids containing Additin® RC 2516 can even be
increased by combinations with sulfurized olefins like Additin® RC 2540, zinc
dithiophosphates, e.g. Additin® RC 3038, phosphoric acid partial esters or
ashless phosphorus-sulfur additives like Additin® RC 3890. Additin® RC 2516 is
easily emulsifiable and a well-suited EP additive for soluble oils and
semisynthetic metalworking fluids.
Additin® RC 2516 is EU Ecolabel (EEL)
approved with a maximum treat rate up to 10%, depending on application.

FREQUENTLY ASKED QUESTIONS (FAQ)
EP additives form protective layers on metal surfaces that prevent adhesive wear under boundary and mixed friction conditions. The common types of Extreme Pressure additives are sulfur- based compounds, phosphorus- based compounds, chlorine-based compounds. LANXESS has a bright product portfolio of sulfur-based products Additin® EP and phosphorus-based products Additin® AW.
They are essential ingredients of most metalworking fluids, industrial lubricants like gear oils or slideway oils and EP greases.
They prevent cold welding of the gears tooth faces and flanks under high pressure conditions, particularly during starting, stopping or shock load processes.
This finally depends on the specific process or application in which the lubricant is supposed to be used. Our Application Technology team is happy to support you with further information. Please contact us here.
Sulfur carriers, chlorinated paraffins, some phosphorus compounds.
Short chain chlorinated paraffins (chain-length C10 – C13) are already banned and eliminated from metalworking fluid formulations in Europe and many other countries, due to their persistency in the environment with a high potential for bioaccumulation, and because of their classification as toxic to aquatic organisms, carcinogenic to rats and mice and possibly carcinogenic to humans. Medium chain chlorinated paraffins (chain-length C14 – C17) are also already banned or at least supposed to be banned in many countries within the next years because of their risks to the ecosystem and to human health. Many chlorinated paraffins are categorized according to the globally harmonized system of classification and labelling of chemicals as “very toxic to aquatic life with long lasting effects”. Sulfur carriers do not show any kind of hazard classification.
Depending on the specific metalworking process and the metal that is machined, different sulfur carriers or synergistic combinations of sulfur carriers and other additives can even exceed the performance of CLPs in metalworking fluids.
