[Problem] To provide an aqueous coating agent composition (in particular, an aqueous coating composition for lubricating films that contains a solid lubricant) which as a whole is excellent in terms of flowability, applicability, and storage stability and which is capable of forming satisfactory and smooth coating films effective in stick-slip inhibition. [Solution] The problem can be solved with an aqueous coating agent composition which comprises (A) a curable resin in an aqueous emulsion form, (B) a surfactant, (C) solid particles, (D) one or more nitrogenous heterocyclic compounds, (E) a film-forming silicone in an aqueous emulsion form, and (F) water. In particular, it is preferable that the (C) component comprise a solid lubricant. In view of the environmental regulations, it is especially preferable that the (D) component be 1,3-dimethyl-2-imidazolidinone.

The present invention relates to a lubricating mixture, which contains glycerides of natural origin and fatty acid alkyl esters. The glycerides are at least partly mono and/or diglycerides which form a mass fraction of 10% in the mixture. In a temperature range from 10 C. to at least 15 C. the mixture has a liquid phase with a solid fraction of 1 vol. %, which is formed from a fraction of glycerides and/or fatty acid alkyl esters. The mixture can be formed entirely from renewable raw materials, has a high viscosity index and is particularly suitable as a lubricant for use in gearings, electric motors or internal combustion engines.

In a threaded joint for pipes constituted by a pin and a box, each having a contact surface comprising a threaded portion and an unthreaded metal contact portion, the contact surface of the pin has a solid corrosion protective, preferably transparent coating based on a UV-curable resin and the contact surface of the box has a solid lubricating coating having plastic or viscoplastic rheological behavior which is preferably formed by the hot melt technique from a composition comprising a thermoplastic polymer, a wax, a metal soap, a corrosion inhibitor, a water-insoluble liquid resin, and a solid lubricant.

The present invention relates to a gear oil composition containing a base stock and at least 0.01 wt % of a friction reducing additive which comprises a glycerol and/or polyglycerol C.sub.12 to C.sub.24 saturated fatty ester. The gear oil composition is suitable for use in gear boxes in automotive, industrial and marine applications.

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.

The invention provides a lubricating composition containing an oil of lubricating viscosity and an ashless ketone compound with at least one of a hydroxy group and an ether linkage attached to the carbon atom adjacent to the carbonyl carbon of the ketone, especially -hydroxyketone. The invention further relates to methods of lubricating an internal combustion engine by supplying the described lubricating composition to the internal combustion engine. The invention further relates to the use of the -hydroxyketone compound as a friction modifier and an antiwear agent.

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.

The present invention provides a cutting method comprising a cutting step of cutting a workpiece material with a cutting tool to thereby form a through-groove in the workpiece material, wherein in the cutting step, the through-groove is formed in the workpiece material by cutting the workpiece material with the cutting tool while contacting a cut-assisting lubricant with the contact portion of the cutting tool with the workpiece material and/or the contact portion of the workpiece material with the cutting tool, and the workpiece material comprises a fiber reinforced composite material.

The present disclosure provides processes for producing alkylated fatty acids and derivatives thereof. In at least one embodiment, a process includes introducing a terminal alkyl transferase and a fatty acid into a bioreactor. The process includes introducing an internal methyl transferase and internal methyl reductase into the bioreactor or a second bioreactor. The process includes obtaining an alkylated fatty acid having a methyl substituent located at an internal carbon atom of the fatty acid and a methyl substituent or ethyl substituent located at a carbon atom alpha to the terminal carbon atom of the fatty acid.

The invention relates to rice bran wax oxidates that have optionally been derivatized and to micronized wax additives (MWAs) comprising optionally derivatized rice bran wax oxidate, having a volume-average particle size d.sub.50 of between 1 and 50 m, and to the production thereof and use thereof in printing inks, paints and coatings.
