HYDRAULIC FLUID

HYDRAULIC FLUID

A hydraulic fluid which is an oil-in-water emulsion and comprises from 90-99%w of water, from 0.5-5%w of a lubricating oil with a kinematic viscosity at 40 DEG C of at least 160 cS, preferably at least 300 cS, and an emulsifier, which preferably contains one type of polymeric component which is deri...

Zusammenfassung:A hydraulic fluid which is an oil-in-water emulsion and comprises from 90-99%w of water, from 0.5-5%w of a lubricating oil with a kinematic viscosity at 40 DEG C of at least 160 cS, preferably at least 300 cS, and an emulsifier, which preferably contains one type of polymeric component which is derived from an oil-soluble complex monocarboxylic acid, and another type of polymeric component which is the residue of a water-soluble compound containing polyoxyalkylene chains.
