ABSTRACT:
A lubricant contains a fire-resistant water/glycol mixture combined with polytetrafluoroethylene, and is useful in the hydraulic systems of die casting machines, for example. The addition of polytetrafluoroethylene enhances the lubricity of fire-resistant hydraulic fluids thereby reducing the associated equipment maintenance. A preferred lubricant is formed by sequentially and homogeneously blending its constituents thereby prolonging the shelf life of the final product.
