A coating for a medical device or appliance may include a fluoropolymer and a polyimide. Such coatings may provide a lubricious exterior surface that facilitates insertion or displacement of a medical device in a body lumen. Some coatings that include a fluoropolymer and a polyimide may, among other functions and characteristics, provide increased strength and/or durability relative to some other coatings.

The present disclosure relates to a method for coating a coiled sucker rod, the method comprising: (a) transferring the coiled sucker rod from a first reel to a thermal spray metal gun system with a conveyance system; and (b) applying a thermal spray metal coating on the coiled sucker rod with a thermal spray metal gun system to form a thermal spray metal coated coiled sucker rod.

A liquid repellent composition which can provide an article with good alcohol repellency is provided. A liquid repellent composition comprising a fluorinated polymer and an aqueous medium, wherein the fluorinated polymer comprises units based on a monomer a, units based on a monomer b and units based on a monomer c. Monomer a: a compound represented by CH.sub.2═CH—R.sup.f (wherein R.sup.f is a C.sub.1-8 perfluoroalkyl group). Monomer b: a fluorine-free nonionic surfactant having a polymerizable carbon-carbon double bond. Monomer c: another monomer copolymerizable with the monomer a and the monomer b.

Described herein is a building panel comprising: a substrate, and a coating applied to the substrate, the coating comprising a blend of an antimicrobial composition, a binder, and a pigment, wherein the antimicrobial composition consists essentially of zinc borate.

A wire coating device and method are provided. The wire coating device includes a wire holder unit fixing both ends of a wire, a fiber forming unit including a first fiber forming module and a second fiber forming module that are applied with a polymer solution, face each other, and form fibers while approaching each other and retreating from each other, and a control unit adjusting a tension of the wire by controlling the wire holder unit and crossing the wire and the fibers by controlling the fiber forming unit. The fiber forming unit spins the wire using a longitudinal direction of the wire as an axis. The fibers are attached and coated on the wire when the wire and the fibers cross each other. The wire coating method can improve an adsorption state of coated fibers by including a post-processing step.

Compositions including a filler, an emissivity agent, a crosslinking facilitator, and a metal silicate binder are disclosed. The compositions can be curable at ambient conditions. Methods of coating overhead conductor and power transmission line accessories with such coating compositions are also disclosed.

A geosynthetic clay liner (GCL). The GCL may include a substrate layer, a bentonite layer applied onto the substrate layer, and a water-soluble polymer suspended in a non-aqueous medium and spray-applied over the bentonite layer.

A device for coating a wire with polymer fibers and method thereof are provided. The device includes a wire holder unit fixing both ends of a wire, a fiber forming unit including a first fiber forming module and a second fiber forming module that receive a polymer solution, face each other, and form fibers while approaching each other and retreating from each other, and a control unit adjusting a tension of the wire by controlling the wire holder unit and crossing the wire and the fibers by controlling the fiber forming unit. The fiber forming unit rotates the wire along an axis which extends in a longitudinal direction of the wire. The fibers are attached and coated on the wire when the wire and the fibers cross each other. The wire coating method can improve an adsorption state of coated fibers by including a post-processing step.

Provided are methods for extending the life of in-service electrical cable having polymeric insulation, comprising injecting a dielectric enhancement fluid composition into the cable, wherein the composition comprises: (a) one or more organoalkoxysilane functional additives (voltage stabilizer-based, hindered amine light stabilizer (HALS)-based, and/or UV absorber-based); and (b) a catalyst suitable to catalyze hydrolysis and condensation of (a), the injected composition providing for rapid initial permeation of (a) into the insulation, and extended retention of subsequent condensation products of (a) in the insulation. Additionally provided are innovative silyl functional ferrocenes (e.g., containing a ferrocene moiety and a silyl function hydrolysable to silanol) having utility as functional voltage stabilizing additives in the methods.

A water-repellent structure includes: a base material; and a water-repellent layer located on a surface of the base material. The water-repellent layer contains water-repellent particles and filler particles having an average particle size that is 20 times or more as large as an average particle size of the water-repellent particles.
