ABSTRACT:
A synthetic dual-purpose fluid for use as a hydraulic fluid and in metal cutting operations, particularly where hydraulic fluid leakage cannot be tolerated in hydraulically operated machines designed for metal cutting purposes. The fluid contains in combination 50-70% of an alkylene glycol, 10 to 25% of an alkanol amine, up to 10% boric acid, and 2 to 25% of a phosphate-modified condensation product of a fatty acid and a dialkanolamine.
