Abstract (en)
[origin: US2009088349A1] The fluid compositions of the present invention include an glycol component that includes a mixture of glycols according the formula: Wherein, typically, at least one of R2, R3, R4 and R5 is an alkyl group. The physical properties of the compositions include a high dry equilibrium reflux boiling point (ERBP), a high wet equilibrium reflux boiling point (WERBP), a low temperature viscosity or any combination thereof. These compositions are particularly useful because their physical properties (e.g., WERBP, ERBP, and low temperature viscosity) meet or exceed the provisions for DOT 3, 4, or 5 brake fluids.
