Abstract
The invention relates to thickened fuctional fluids. The functional fluids can be used in hydraulic systems or as metalworking compositions to cool and lubricate surfaces which are in frictional contact during operations such as the turning, cutting, peeling, or grinding of metals. The functional fluid contains a diluent, a dialkyldithiophosphate, a compound which is a source of molybdate ion, a polyether nonionic surfactant, and an associative polyether thickener.
