Abstract
A water soluble metalworking concentrate is a combination of one or more amines; one or more ferrous corrosion inhibitors; one or more phosphate esters; one or more ether carboxylates; a ricinoleic acid condensate; one or more lubricating agents; deionized water and, optionally, one or more non-ferrous corrosion inhibitors. In use, the concentrate is diluted to a concentration of approximately 5% to approximately 10%. In use, the metalworking fluid exhibits excellent lubricity, low foam generation, emulsion stability, protection of ferrous and non-ferrous metals, biostatic stability and environmental compatibility.
