THICKENING SYSTEMS FOR HIGH WATER BASED FUNCTIONAL FLUIDS AND THE HIGH WATER BASED FUNCTIONAL FLUIDS CONTAINING THESE THICKENING SYSTEMS

摘要

Thickening systems for high water based functional fluids and the high water based functional fluids containing these thickening systems of the disclosure The invention relates to the use of combinations of water-soluble polymeric polyether polyols, in which at least 50% of the terminal hydroxyl groups are blocked by reaction with a monoisocyanate incorporating a long-chain aliphatic hydrocarbon radical, and certain surfactants as thickener systems for high water based functional fluids and to the thickened high water based functional fluids.
