Provided is a lubricant composition for plastic working of a ferrous material, the lubricant composition being excellent in lubricity and releasability and not staining the work environment black. A lubricant composition for plastic working of a ferrous material is used, the lubricant composition containing (a) an alkali metal salt of an organic acid, (b) water-based resin particles, (c) a water-soluble polymer, and (d) water, the (b) water-based resin particles including particles having a particle diameter of not more than 0.1 μm in an amount of more than 5% by weight relative to a total amount of the (b) water-based resin particles.

A water-based lubricating grease composition includes at least 40 wt % water; a salt-based thickener; a polymer-based thickener; and optionally, an inorganic solid-based thickener. A process for preparing the water-based lubricating grease composition may include blending a suitable amount of water with a salt-based thickener to provide a thickened water-based grease, wherein the salt-based thickener is obtained from contacting a base with a fat; and adding a polymer-based thickener to the thickened water-based grease.

A water-miscible functional fluid includes: a neutral photosensitizer having an isoalloxazine skeleton; and an antioxidant, wherein the antioxidant is a radical scavenger or a peroxide decomposer.

The present invention describes a pipe sealing compound/adjunct lubricant used to prevent gas or liquid leaks when applied to pipe threads and other connections of the same. The compound relies on silicone oil lubricant(s) and one or more friction modifier(s), viscosity builder(s) and filler material(s). The compound contains a viscoelastic liquid that does not have a curing phase and is resistant to hardening and/or drying. The compound is chemically resistant to a wide variety of liquids and gases, is food safe and can withstand extreme high or low temperatures and precipitous temperature fluctuations. The compound has been found to exhibit an inverse pressure to leak rate phenomena.

Provided is a one-pack type ultraviolet-thickable thermally conductive silicone grease composition which, at the initial stage, has a low viscosity (is easy to apply) but has high shape retentivity and which, after curing, is pliable (has low hardness). The ultraviolet-thickable thermally conductive silicone grease composition comprises, as essential components, (A) an organopolysiloxane having a viscosity at 25° C. of 50-100,000 mPa.Math.s and containing at least one alkenyl group in the molecule, (B) a liquid organohydrogenpolysiloxane which has a viscosity at 25° C. of 100 mPa.Math.s or less, contains 2-10 silicon-atom-bonded hydrogen atoms in the molecule and contains at least one alkoxy and/or epoxy group bonded to a silicon atom through an alkylene group and in which the polysiloxane has a degree of polymerization of 15 or less and the skeleton of the polysiloxane includes a cyclic structure, (C) a photoactivable platinum complex curing catalyst, and (D) a thermally conductive filler having a thermal conductivity of 10 W/m.Math.° C. or greater.

A method for producing a lubricant in producing an overbased calcium sulfonate, which is converted from the vaterite form into the calcite form and, finally, a calcium sulfonate grease is produced by heating the mixture. A lubricant may comprise at least one ester composition, calcium carbonate and at least one overbased alkylbenzene sulfonate. The basicity of the mixture is limited during the preparation of the overbased calcium sulfonate to a TBN of at most 550 mg KOH/g and during the conversion of the calcium sulfonate to a TBN of at most 450 mg KOH/g. Both the calcium sulfonate and the grease containing said calcium sulfonate may be produced exclusively on an ester basis, so that the end product does not contain any mineral oil and is therefore easily and completely biodegradable.
