Provided is a coating film that is less likely to be deteriorated even after exposure to hydrogen peroxide. The coating film is for use in an environment including exposure to hydrogen peroxide and includes a fluorine atom and a urethane bond.

The disclosure relates to an omniphobically coated fluid channel including a channel defining an interior channel surface and a flow volume, and a thermoset omniphobic composition as a coating on the interior channel surface. The thermoset omniphobic composition (such as an omniphobic polyurethane or epoxy composition) includes a thermoset polymer with first, second, and third backbone segments. The first, second, and third backbone segments can correspond to urethane or urea reaction products of polyisocyanate(s), amine-functional omniphobic polymer(s), and polyol(s), respectively, for omniphobic polyurethanes. Similarly, the first, second, and third backbone segments can correspond to urea or beta-hydroxy amine reaction products of polyamine(s), isocyanate-functional omniphobic polymer(s), and polyepoxide(s), respectively, for omniphobic epoxies. The thermoset omniphobic composition coating protects the underlying channel material (such as metal material) from corrosion, and it can further reduce the pressure drop of fluid flowing through the channel. The omniphobically coated fluid channel can be used as a component of a heat transfer apparatus.

Composite materials are made by impregnating a non-conductive material with a conducting monomer to form a monomer-impregnated non-conductive material, and polymerizing the monomer-impregnated non-conductive material to form the composite material. The composite materials are used in medical devices and implants.

A disposable toothbrush having a toothpaste composition distributed over the bristles of the toothbrush without the use of metal graft initiators and catalysts, and in which the toothpaste and the flavoring is maintained for an extended period of time.

Disclosed is a method for treating a grained material. A nonlimiting example of the method includes the operations of providing a workpiece having grains, exasperating a surface of the workpiece to open the grains, applying at least one coat of a base paint to the exasperated surface, applying at least one layer of clear coat on the base paint, applying at least one of a glaze and a paint on the clear coat, and surface treating to reveal grains of the workpiece. Disclosed also are items of furniture and sheet materials treated by the aforementioned process.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

An aqueous resin dispersion wherein a polymer (C) obtained by bonding a polyolefin (A) to a polyether resin (B) is dispersed in water; and the polyether resin (B) contains a polyether resin (B1) having an HLB of less than 8 and a polyether resin (B2) having an HLB of 8 to 20 according to calculation by the Griffin method.

In accordance with the present application, there is provided a release liner and method of preparing a liner for a label assembly. The release liner includes paper having a first side that does not have a machine finish or gloss finish or a coating; and a silicone treatment applied to the first side of the paper. The method of preparing a liner for a label assembly includes applying a coat of silicone to a paper at a side of the paper that does not have a machine finish or gloss finish and is otherwise uncoated; and curing the silicone. The release liner includes paper having a silicone coat weight of 0.5 lb/ream or less.

A drying method of a polyimide paste which can maintain a printing shape while maintaining productivity includes an organic solvent and a polyimide resin dissolved in the organic solvent, and which becomes cured polyimide by being cured as a result of being dried and heated, the drying method including a step of applying the polyimide paste to a surface of a base material, a step of applying a solvent including a polar material to a surface of the base material at least at a portion where the polyimide paste is applied, and a step of, after applying the solvent including the polar material, drying the polyimide paste and the solvent including the polar material.

An orthopaedic implant comprising a titanium substrate having silver deposited thereon, wherein the silver is operable to be eluted at a rate of at least 0.25 g/cm2 24h-1, for at least 14 consecutive days, in use. The invention also extends to a method of producing an orthopaedic implant and use of the same.
