Abstract (en)
A metalworking fluid concentrate with improved stability and overall performance is described, comprising(A1) 1.5 - 4.0wt% of a blend of a C<sub>8</sub>-C<sub>30</sub> alcohol with a fatty acid ester R<sup>1</sup>CO2R<sup>2</sup> where R<sup>1</sup> is a C<sub>8</sub>-C<sub>30</sub> acid residue and R<sup>2</sup> is a C<sub>1</sub>-C<sub>12</sub> alcohol residue;(A2) 1.5 - 4.0wt% wt% of a surfactant;(A3) 0.5 - 3.0wt% of additives selected from anti-gelling agents, foam control agents, antiwear additives, extreme pressure additives, pH buffers and biocides;(B1) 6 - 15wt% of an amine which is water-soluble at room temperature;(B2) 2 - 5wt% of a corrosion inhibitor which is water-soluble at room temperature;(B3) 5 - 15wt% of a compound selected from ethylene oxide or propylene oxide block copolymers, ethylene oxide or propylene oxide random copolymers, ethylene oxide or propylene oxide polymer esters and ethylene oxide ethers; and(B4) 60-80wt% of water.
