Abstract
The present invention relates to an aqueous lubricant composition for the lubrication of a stationary or mobile drive system, comprising at least: deionized water; at least one polyalkylene glycol; at least one antifreeze compound chosen from glycols, and at least one phosphorus compound. It also relates to the use of this aqueous lubricant composition for the lubrication and cooling of a stationary or mobile drive system.
Claims18
