Abstract (en)
[origin: WO9204428A1] The present invention relates to a hydraulic fluid composition comprising: (a) a polyalkylene glycol base fluid and (b) as an anti-mist additive, an alkylene-vinyl ester copolymer having a molecular weight of between about 5,000 and 100,000 and soluble in said base fluid. In another aspect, the present invention relates to a process for imparting flame retardancy and reduced wear characteristics to a hydraulic system which comprises adding to the hydraulic system the above-identified hydraulic fluid composition.
