The invention relates to a coating agent for spray coating an object with at least one alkylsilane used for creating a hydrophobic and/or oleophobic coating and additives used for facilitating application. The alkylsilane is provided at a concentration of less than 10 percent while the additives comprise a solvent and/or a diluted solvent which is selected at a low viscosity such that the coating agent can be sprayed in droplets having an average diameter of less than 100 µm, preferably less than 50 µm.

The invention relates to a method for coating a substrate with a layer of a material, such as a metal, in which a quantity of electrically conductive material is vaporized in a space with a low background pressure and energy is supplied to the material which is to be vaporized in order to vaporize this material. According to the invention, the material which is to be vaporized, while it is being vaporized, is kept floating, without support, in the space and is enclosed in an alternating electromagnetic field, the alternating electromagnetic field being generated with the aid of a high-frequency alternating current. The invention also relates to a device for coating a substrate and to a substrate.

Coatings are formed by applying to article a copolymer of a water soluble base polymer having graft polymerized thereto an organic moiety that includes a group that reacts with water to form a silanol group, and then curing the copolymer to form a crosslinked hydrogel coating that is absorbent, lubricious and substantially non-water soluble. Coating compositions, coated articles the subject coatings are also described.

The invention provides a coating implement for applying a nonvolatile liquid for protection treatment, which does not dissolve a coloring material, to a recorded product which is provided with a porous layer as an ink-receiving layer on the surface of a substrate, and on which an image has been formed with the coloring material adsorbed on at least the porous layer, thereby protecting the image, wherein a coating surface for applying the liquid to the porous layer having the image is supported by a supporting member, and the coating surface can hold the liquid.

The invention relates to a composition for producing a heat-insulating coating comprising at least one radiation-absorbing compound and at least one IR-reflector component, to a heat-insulating coating comprising this oriented, cured composition, and to a process for producing said coating.

In one embodiment, a composition (10) to be mixed with a molten metal to make a metal matrix composite, the composition characterized by: a ceramic reinforcing filler (12), the ceramic reinforcing filler not being wettable by molten aluminum and/or not being chemically stable in molten aluminum, the ceramic reinforcing filler being coated with a ceramic material, the ceramic material being wettable by and chemically stable in molten aluminum. In a related embodiment, a composition (20) to make a porous preform to be infiltrated by molten metal to make a metal matrix composite, the composition characterized by: a ceramic reinforcing filler (23), the ceramic reinforcing filler not being wettable by molten aluminum, the ceramic reinforcing filler being coated with a ceramic material (22) and optionally with a metal (21) such as nickel, the ceramic material being wettable by molten aluminum. The ceramic material can be coated on the ceramic reinforcing filler by a vacuum deposition technique such as vacuum sputtering.

A method of treating a domestic, institutional, industrial, and/or commercial surface, the method comprising the step of contacting a surface with a surface-treating composition containing a water-soluble, sulfonated/carboxylated polymer, is provided.

A coating apparatus (100) and coating method include a device for conveying an object (W) to be coated; a coating device (4) which is disposed in a vicinity of a conveyed surface of the object (W), and which discharges a coating liquid, and which forms a bridge of the liquid between the device (4) and the object (W) which is conveyed by the device for conveying an object to be coated, and which coats the liquid on at least one surface of the object (W); and a gas stream blowing device which, immediately after starting of coating, blows out a gas from a direction substantially opposite to a object conveying direction, toward a portion of the object where coating starts.
