A method is provided that forms a solid film on a bearing component of a rolling bearing. A solution containing a fluorine compound and a lubricant having no functional group is allowed to adhere to the bearing component as a liquid film, the fluorine compound containing 3-(trimethoxysilyl) propyl methacrylate, hexafluoropropene, and methyl methacrylate as components. The solid film is formed on the at least one of the bearing components by hardening the adhering liquid film.

The invention relates to the use of an O/W emulsion, in particular a PIT emulsion, for lubricating conveyor belt systems in food industries as well as a lubricant concentrate based on an O/W emulsion, in particular a PIT emulsion, of wax esters.

Provided is a thermally conductive silicone grease composition that comprises: (A) an organopolysiloxane having a specific kinematic viscosity; (B) an organopolysiloxane having a specific kinematic viscosity; (C) a spherical aluminum oxide powder which has a specific average sphericity, a specific number of surface hydroxyl groups, and a specific average particle size, and for which the proportion of coarse particles in a laser diffraction type particle size distribution of 25 to 45 μm is within a specific range; and (D) a spherical and/or amorphous zinc oxide powder which has a specific average particle size, and for which the proportion of coarse particles in a laser diffraction type particle size distribution of 25 to 45 μm is within a specific range. The composition has a thermal conductivity measured by the hot disk method conforming to ISO 22007-2 of 2 W/m.Math.K or more and less than 5.5 W/m.Math.K, has a coefficient of viscosity measured by a spiral viscometer at a rotation frequency of 10 rpm of 5 to 800 Pa.Math.s, has insulation properties and high thermal conductivity, and has excellent flowability, workability, and heat dissipation properties.

The present invention relates to compositions in the form of silicone oil emulsions intended to be applied to curing bladders as a mould-release agent during tyre production.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

Coating compositions, coatings, and coated articles are provided exhibiting drag-reducing properties. The drag reduction can lead to improved flow, e.g. an improved measure of slip length, over both laminar and turbulent flow conditions, e.g. for Reynolds numbers less than 2,000 to as much as about 500,000. The coating compositions include abase matrix and an effluent polymer dispersed in the base resin in such a way that, when an exposed surface of the drag-reducing coating is exposed to an aqueous medium, the effluent polymer migrates to the exposed surface of the drag-reducing coating and into the aqueous medium at or near the exposed surface to create a diluted effluent polymer solution in the aqueous medium at or near the exposed surface; wherein the diluted effluent polymer solution reduces a drag of the surface moving through the aqueous medium.
