ADDINOL Erosion Fluid ED 2 L is a low-viscosity dielectric oil for electrical discharge machining of metals, based on dearomatized mineral oil raffinate with a very low aromatic content. The composition provides good dielectric properties, rapid flushing of removed particles and heat removal from the working zone during roughing and finishing operations.

The oil is chemically resistant to stresses caused by electrical discharges as well as the effects of air, temperature and contamination. Low viscosity facilitates flow through filtration systems, while the narrow boiling range and low evaporation tendency contribute to lower oil consumption and less pronounced odour during use in EDM machines.
