In one example, a print medium includes pigment particles sized less than a hundred nanometers and frictional control additives. An undercoating is disposed between the base material and top coating. The undercoat includes a first sub-layer comprising a pigment fixative agent and a second sub-layer comprising a dye fixative agent. The top coating forms a protective and low friction coating over the undercoating.

This invention provides a method for manufacturing a decorative-part that makes it surely and easily possible to provide fine hairline-patterns that are similar to real texture by a laser-drawing process. By the method for manufacturing the decorative part, a laser-drawing process is done onto the coating-film 21 that has been formed on the surface 13 of the three-dimensional part-material 12. In this process a laser-processed groove-group 23 consists of a number of laser-processed grooves 24, 25, thus providing the hairline-pattern 22 on the coating-film 21. The laser processed groove-group 23 consists of various types of arc-like laser-processed grooves 24, 25 that comprise different curvature radii R of 1,000 mm or more. The arc-like laser-processed grooves 24, 25 are arranged extending appropriately in the same direction and of which each groove crosses at three degrees or less in irregular overlaps that show the line of each groove being wider than any other part.

The present invention provides a surface treatment method. The method comprises an anti-static treatment step of coating a treatment target with an anti-static agent comprising an electrolyte (e1), a hydrophilic polymer (a) and water, and having electrical conductivity of 15 mS/m or more to obtain a coated film (A), drying the coated film (A) to obtain an anti-static layer, and a hydrophilizing treatment step of coating the anti-static layer with a hydrophilizing treatment agent comprising a hydrophilic polymer (b) and an alcohol to obtain a coated film (B), and drying the coated film (B), followed by rinsing thereof.

Processes are described herein for preparing medical devices and other articles having a low-fouling surface on a substrate comprising a polymeric surface. The polymeric surface material may possess a range of polymeric backbones and substituents while providing the articles with a highly efficient, biocompatible, and non-fouling surface. The processes involve treating the substrate to reduce the concentration of chemical species on the surface of or in the substrate without altering the bulk physical properties of the device or article, and thereafter forming a grafted polymer layer on the treated substrate surface.

An applicator making it possible to apply a coating product on a surface to be coated, including at least one row of nozzles, among which at least the first nozzle in the row includes a valve, the applicator further including at least one distance sensor, to measure an application distance of the first nozzle from a point in front of the latter on a path of the applicator, and an electronic control unit of the valve, which is programmed to collect the distance measured by the distance sensor and, based on the collected distance value, to open or close the valve.

Optical products and methods of making them are disclosed, the optical products comprising a polymeric substrate and a composite coating. The composite coating, in turn, comprises: a first layer comprising a polyionic binder, and a second layer comprising insoluble particles that absorb electromagnetic energy and insoluble particles that absorb relatively little visible light. Each of the first layer and the second layer includes a binding group component which together form a complimentary binding group pair.

A method for applying a waterproof coating to a transducer component includes the steps of cleaning and promoting bonding on the transducer component by immersing the component in a mixture of isopropyl alcohol, deionized water, and siline. The component is then air dried and rinsed in pure isopropyl alcohol. After drying, the component is vacuum baked and subjected to a vacuum for twelve hours. A parylene coating is provided to the component surface. The parylene coating is abraded, and the surface is rinsed with pure isopropyl alcohol. After drying, polyurethane is provided on the abraded parylene surface. The polyurethane is cured to form a waterproof coating on the transducer component. In further embodiments, a second parylene coating can be provided outside the polyurethane.

A method for producing a coated proppant having an intermediate cross-linked terpolymer layer includes mixing a monomers solution including a first monomer, a second monomer that is different from the first monomer, a cross-linking agent, and an initiator. The proppant particle is combined with the monomers solution, and the monomer solution on the surface of the at least one proppant particle is polymerized to form at least one proppant particle having the intermediate cross-linked terpolymer layer on a surface of the at least one proppant particle. A resin solution including an epoxy resin, a curing agent, and graphene is mixed, and combined with the at least one proppant particle having the intermediate cross-linked terpolymer layer on a surface of the at least one proppant particle. The resin solution is cured to form the coated proppant comprising an intermediate cross-linked terpolymer layer.

A multi-layer coating includes: a first basecoat layer applied over at least a portion of a substrate; and a second basecoat layer applied over the first basecoat layer. The first basecoat layer and second basecoat layer are formed from compositions having a polyhydrazide and core-shell particles dispersed in aqueous mediums. The core-shell particles of the first basecoat composition includes (1) a polymeric core at least partially encapsulated by (2) a polymeric shell comprising urea linkages, and keto and/or aldo functional groups. The polymeric core of the core-shell particles of the first basecoat composition and the second basecoat composition are each independently covalently bonded to at least a portion of the polymeric shell of the core-shell particles.
