ADDITIN® EP

Lanxess

Products in the Additin® Extreme-Pressure (EP) range are generally used as a backbone in the formulation of modern neat oil and water-based metalworking fluids as well as greas-es, transmission and slideway oils. Rhein Chemie Additives provides the right solution for any application and offers com-petent assistance for selecting the most suitable alternatives.
Additin® EP products chemically react with the metal surface to form a protective sulfur-containing film. This reduces direct metal-to-metal contact, thereby avoiding friction as well as material damage, e.g. damage caused by welding.
This product group was specially developed to meet the latest requirements of the lubricant oil industry and offers precisely the characteristics required in high-performance environments:
- Low-odor, light-colored additives with good solubility in many base fluids
- Multifunctional performance due to efficient friction reduction and anti-aging protection

Additin RC 2411

Additin RC 2411 is a light-coloured, very inactive sulphur carrier with excellent EP and AW properties. Due to its special production process Additin RC 2411 is especially suitable for the formulation of  metalworking fluids for working of nonferrous metals and aluminum alloys.By virtue of specially selected raw materials Additin RC 2411 exhibits a high lubricity and good friction modifying properties.

Additin RC 2515
Additin RC 2515 is a nearly odourless, light-coloured sulphur carrier.
Due to its outstanding EP properties and low activity against nonferrous metal.
Additin RC 2515 is ideally suited for formulating heavy metal-free EP greases and slideway oils with good anti-stick-slip behaviour.
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.

Additin RC 2541
Additin RC 2541 is a dialkylpolysulphide with low copper corrosion and improved load carrying capacity.
It is suitable for use in applications where high sulphur content and reactivity is required, but yellow metal compatibility at moderate temperatures is also necessary.

Additin RC 2811

Additin RC 2811 is a dark-coloured sulphur carrier. It is mainly used in metalworking fluids and EP greases. Due to its low active sulphur content, Additin RC 2811 is also suitable for use with yellow metals. Optimum performance of the finished formulation can be obtained by combination with zinc dithiophosphates, e.g. Additin RC 3038.
