The present invention provides a lubricant composition which can be washed off cold and the use thereof for application to a metal strip as anti-corrosion, wash and/or forming lubricant. The composition is 50 to 90 wt % base fluid, 3 to 15 wt % sulfonate-based corrosion inhibitor, 1 to 20 wt % ester component, 0.5 to 3 wt % phosphorus source component or 1 to 10 wt % sulfur source component as high-pressure/anti-wear additive, 1 to 15 wt % emulsifier, 0.05 to 1 wt % carboxylic acid component, 0.05 to 1 wt % aminic and/or phenolic antioxidant, 0.5 to 5 wt % wax and/or thickener component, based in each case on the total weight of the composition. Further disclosed is a dry lubricant composition which can be washed off cold.

A water-soluble quenching fluid composition prepared by blending: water, at least one kind selected from a polyoxyalkylene glycol and a derivative thereof (A), and at least one kind selected from an alkylene glycol ether (B) and a monocarboxylic acid (C), the polyoxyalkylene glycol or a derivative thereof (A) having a mass average molecular weight of 10,000 or more and 100,000 or less, the alkylene glycol ether (B) having a boiling point of 200 C. or more and a molecular weight per 1 mol of 1,000 g/mol or less.

The present invention concerns a coolant, present as an emulsion in the form of a concentrate, for machining fiber-reinforced plastics and material combinations containing fiber-reinforced plastics and metals; furthermore, the present invention also concerns a coolant, present as a solution in the form of concentrate, for machining fiber-reinforced plastics.

Stable water-in-oil emulsions suitable for use as fire-resistant aerosol multipurpose lubricants. The water-in-oil emulsion comprises a synthetic ester base oil, compatible invert emulsifier, water, and a preservative. The aerosol apparatus employs a larger than standard stem orifice to produce a non-flammable aerosol.

A water-soluble lubricant composition for warm and hot plastically working of an aluminum material comprising (A) hydrophilic polyester resin, (B) alkali metal salt of a polymaleic acid resin, (C) alkali metal salt of carboxylic acid and (D) water, and optionally (E) a wax.

The present invention provides a lubricant material for assisting machining process comprising a high molecular weight compound (A) having a weight average molecular weight of 5?10.sup.4 or higher and 1?10.sup.6 or lower, a medium molecular weight compound (B) having a weight average molecular weight of 1?10.sup.3 or higher and lower than 5?10.sup.4, and a carbon (C) having an average particle size of 100 ?m or larger.

The present invention is a lubricating agent containing a compound represented by the following formula 1: ##STR00001## wherein R.sup.1 and R.sup.2 each represent a hydrocarbon group with 6 or more and 24 or less carbons; A.sup.1O and A.sup.2O each represent an alkyleneoxy group with 2 or more and 4 or less carbons; x1 and x2 are average numbers of added moles, and each represent a number of 0 or more and 10 or less; and M is a cationic ion.

A lubricant composition fed to an intermediate transfer belt in an intermediate transfer-type electrophotographic image forming method includes solid lubricant particles that are inorganic compound particles having an average size of 120 nm or less and a binder disposed on surfaces of the solid lubricant particles. The content of the binder is 0.01% by mass or more and 20.00% by mass or less of the amount of the lubricant composition.

A method for reducing aqueous phase separation of an emulsion comprising ethanol-based fuel and a lubricating oil comprising molybdenum ester amide complex, comprising the step of adding to the lubricating oil a dispersant polyalkyl (meth) acrylate (DPMA) in an amount from about 0.01 to about 0.5% by weight of the lubricating oil, such that the weight ratio of molybdenum to DPMA is about 2.05 or less.

Problems addressed by the present invention are to provide a lubricant composition that is capable of being used as an alternative to chemical conversion treatment by means of phosphate, to provide a lubricant composition having practical stable lubricative performance without the need for additional unwanted operations, and to provide a method for using this to form a lubrication coating, and a metal workpiece at which a lubrication coating is formed on a surface thereof. Provided as a means for solving such problems is a lubricant composition for causing formation of a hemimorphite-containing lubrication coating that contains a silicate compound (e.g., colloidal silica) and water-soluble zinc in solution.
