Abstract
A metalworking composition containing 2-hydroxyethyl-(3-chloro-2-hydroxypropyl)sulfide in an aqueous medium. A method for enhancing the extreme pressure lubricating properties of an aqueous metalworking composition by admixing therein 2-hydroxyethyl-(3-chloro-2-hydroxypropyl)sulfide.
Claims8
A metalworking composition comprising an extreme pressure effective amount of 2-hydroxyethyl-(3-chloro-2-hydroxypropyl)sulfide with an effective amount of (1) lubricity additive, (2) pH adjusting compound, (3) rust inhibitor and (4) biocide in an aqueous medium.
A method for enhancing the extreme pressure lubricating properties of an aqueous metalworking composition comprising an effective amount of lubricity additive, pH adjusting compound, rust inhibitor, and biocide said method comprising admixing therein an effective amount of 2-hydroxyethyl-(3-chloro-2-hydroxypropyl)sulfide.
A method for enhancing the extreme pressure lubricating properties of a metalworking composition concentrate comprising a lubricity additive in an amount of about 5 to about 10 weight %, a pH additive adjusting compound in an amount of about 5 to about 10 weight %, a rust inhibitor in an amount of about 1 to about 5 weight %, and biocide in an amount of about 0.1 to about 1.0 weight % of the total composition, said method comprising admixing therein about 5 to about 10 weight % of 2-hydroxyethyl-(3-chloro-2-hydroxypropyl)sulfide.
