    摘要: An aqueous hydraulic fluid composition comprising (i) a salt of formic acid, and (ii) one or more lubricants such as a monovalent metal salt, ammonium, or amine salt of a dicarboxylic acid, is described in which the aqueous hydraulic fluid composition demonstrates increased thermal stability when exposed to elevated temperatures for a prolonged period of time while being able to tolerate the presence of 10% v/v synthetic seawater. The aqueous hydraulic fluid composition contains less than about 20% by weight (preferably none or substantially none) of an oil selected from the group consisting of mineral oils, synthetic hydrocarbon oils, and mixtures thereof. The hydraulic fluid preferably contains no glycols in some embodiments. The pH of the hydraulic fluid is preferably from 8 to 10 and is maintained by a buffer which preferably comprises borax in some embodiments.

    摘要: The present invention provides a thermally conductive grease composition which scarcely increases in hardness during high-temperature heating and has a minimized reduction in growth, containing:
    (A) an organopolysiloxane including at least two alkenyl groups per molecule, the 25°C kinetic viscosity being 5,000 to 100,000 mm 2 /s;
    (B) a hydrolysable methyl polysiloxane, trifunctional at one terminus, represented by general formula (1)

    (R 1 is a C 1-6 alkyl group, and a is an integer 5 to 100);
    (C) a thermally conductive filler having a thermal conductivity of 10 W/m·°C or greater;
    (D) an organohydrogenpolysiloxane containing two to five hydrogen atoms directly bonded to a silicon atom (Si-H group) per molecule;
    (E) an adhesion promoter having a triazine ring and at least one alkenyl group per molecule; and
    (F) a catalyst selected from the group consisting of platinum and platinum compounds.
