Abstract
A dielectric fluid composition for electric discharge machining is based on saturated hydrocarbons and contains an additive wherein the additive comprises at least one carboxylic acid or a glycerol ester of a carboxylic acid and at least one amine. Preferably, the additive comprises tall oil fatty acids (TOFA). The saturated hydrocarbons have a low content of aromatic hydrocarbons, which is less than 1% w/w. The additive is present in concentrations from 1 to 25%, preferably 5 to 15% by weight in the dielectric fluid. The additive is soluble in the saturated hydrocarbon basis.
