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.
Soluble in mineral oils and synthetic base oils. However, it is necessary to verify the solubility in the base oils used and the compatibility with other additives.
