    Abstract: Disclosed are fire-resistant hydraulic fluids which comprise:

    (a) about 20% to about 60% by weight water;
    (b) a sufficient amount of a hydroxyalkylated isocyanurate to form a hydraulic fluid with a viscosity from about 100 SUS to about 400 SUS at 100°F, aid hydroxyalkylated isocyanurate having the formula:
    wherein x, y and z are each from about 3 to about 15, and each R is Individually selected from hydrogen and methyl;
    (c) about 0.01% to about 5% by weight of a liquid phase corrosion inhibitor; and
    (d) about 0.01% to about 5% weight of a vapor phase corrosion inhibitor.

    isocyanurate fluids are comparable to known water-based glycol fluids in important operating properties such a lubricity and fire resistance, and have the additional advantage of offering a substantial reduction in the flammability of the residual material resulting from loss of water content.
