Definitions

  • the present invention relates to a low viscosity functional fluid composition
  • a low viscosity functional fluid composition comprising
  • the said low viscosity functional fluid composition is useful in a variety of applications and in particular as a brake fluid, especially for new electronic or automated anti-lock brake systems which require lower viscosity fluids for satisfactory operation at low temperatures.
  • Functional fluid compositions based on borate esters are well known in the art. To be useful for example as DOT 4 or DOT 5.1 brake fluids, these borate ester based compositions must meet stringent physical properties and performance requirements particularly with respect to minimum dry equilibrium reflux boiling point (“ERBP”), minimum wet equilibrium reflux boiling point (“WERBP”) and maximum low temperature kinematic viscosity (e.g. determined at -40°C) while maintaining adequate resistance to corrosion, stability and meeting other physical property requirements such as pH, reserve alkalinity and rubber swell.
