Additin RC 4801 is a succinic acid semi-ester. Due to its special chemical structure it acts as a particularly
effective anticorrosion additive with excellent demulsifying properties. Additin RC 4801 can be used as corrosion
inhibitor where metal-containing anticorrosion additives are not desired.

In industrial oils an effective anticorrosion performance can be obtained with a treatment level as low as 0.03 – 0.05 % by weight.

At higher treatment rates of 1.0 – 10.0 % by weight Additin RC 4801 can be used for the formulation of rust
preventative oils. In these applications the anticorrosion properties of Additin RC 4801 exceeds the performance
of standard calcium or barium sulphonates.


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.

Storage conditions

in a dry place at room temperature approx. 24 months
