Abstract:
Fluid concentrates for aqueous functional fluids useful in hydraulic systems or as metalworking compositions contain
(a) a cloud point raising metal dialkyldithio-phosphate additive having the following structural formula: wherein R 1 , R 2 , R 3 , and R 4 are individually linear or branched alkyl, alkenyl, aryl, arylalkyl and alkylaryl groups having from 1 to 24 carbon atoms; and M is Zn, Sb, Sn, Mg or Mn; preferably Zn or Sb; (b) a polyether nonionic surfactant; and (c) an associative polyether thickener.

Abstract:
Water based functional fluids and antiwear compositions for such functional fluids which comprise: (a) a metal dialkyldithiophosphate, and (b) certain primary amines. This combination of certain primary amines with the metal dialkyldithiophosphate provides improved wear properties over the use of the metal dialkyldithiophosphate alone, particularly at higher operating pressures such as 2000 psig and above.
