Type

Ashless corrosion inhibitor with low acidity

Application

– turbine- and compressor oils
– hydraulic fluids
– industrial gear oils
– mould release oils
– lubricating greases
– rust preventative oils

Additin RC 4802 is a succinic acid derivative with an extremely low acid number. Due to its special chemical
structure it acts as a particularly effective anticorrosion additive with excellent demulsifying properties.

Additin RC 4802 can be used as corrosion inhibitor where metal-containing anticorrosion additives are not desired
and the TAN of semi-esters of succinic acids are too high.

In industrial oils an effective anti-corrosion performance can be obtained at treat levels as low as 0.03 – 0.2 % by
weight.

At higher treat rates e.g. 1.0 – 10.0 % by weight Additin RC 4802 can be used for the formulation of rust
preventative oils. In these applications the anticorrosion properties of Additin RC 4802 exceed the performance of
standard calcium or barium sulphonates.

Solubility

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.
This product is liable to crystallization at low temperatures. If this occurs, gentle warming up to 40 – 50 °C with
agitation will ensure homogenity of the product without adverse effects. Local overheating – above 60°C – must be
avoided.
