IMPROVED METHOD FOR APPLYING PROTECTIVE COVERING TO SURFACES

Coating of surgical devices

The invention provides a method for the coating of a surgical device, wherein the coating is carried out by electrostatic Powder deposition. The device may be a device used in a surgical or diagnostic procedure, including interventional devices as well as implantable devices. Because the coating is applied electrostatically, it is attracted to all parts of the device, not just those parts that are in the 'line of sight' of the spray, as is the case with conventional liquid spray coating. The process allows uniform and reproducible amounts to be deposited and thus drug-eluting coatings can be accurately applied to stents and other surgical devices, resulting in good control over drug release. Furthermore, drug-eluting coats can be applied in a single step, although multiple layers can easily be applied if desired to create a specific drug release profile.

Disclosed is a low volume, space-charge controlled electrostatic spraying which is particularly suitable for use in agriculture but is applicable to industrial and other settings as well. A substance is sprayed through a relatively low voltage nozzle producing finely divided, electrostatically charged particles of the substance.

As the charged particles are subsequently directed to target objects, such as plants, the space-charge density is monitored and the spraying and/or charging systems are controlled to maintain the established optimal level which corresponds to optimal deposition.

Polymer Coating System For Improved Tribological Performance

A novel Aromatic Thermosetting Copolyester (ATSP) can be processed into highly effective wear resistant coatings by blending with polytetrafluorethylene (PTFE) and other additives.

An electrosurgical device coated an epoxy modified rigid silicone powder coating which includes a solvent-free hydroxyl functional solid phenyl silicone resin in the range of about 40% to about 60% parts per weight of the coating; a calcium metasilicate in the range of about 20% to about 40% parts per weight of the coating; an epoxy cresol novalac resin in the range of about 5% to about 15% parts per weight of the coating; an ultra-fine air micronized muscovite mica in the range of about 0% to about 10% parts per weight of the coating; a 60% active powder version of a methyl alkyl polysiloxane in the range of about 3% to about 7% parts per weight of the coating; a high temperature calcination of coprecipitated compound with manganese-copper-iron in the range of about 0% to about 10% parts per weight of the coating; an o-cresol novolac resin in the range of about 0.5% to about 3% parts per weight of the coating; and an acrylate copolymer in the range of about 0.5% to about 3% parts per weight of the coating. This coating is applied to the surfaces of an electrosurgical device minimize the build-up of charred tissue (i.e., eschar) on the surfaces of the electrosurgical device.

Process for preparing coated articles

A process for preparing a coated article which includes the step of electromotively coating an article molded or extruded from a composition having a conductivity of at least about 10 -14 Siemens/cm (S/cm) comprising (a) a thermoplastic polymer, thermoset polymer, or mixture thereof and (b) an electronically conductive charge transfer complex or inherently semiconducting polymer different from (a). It has been discovered that the process of the invention provides a means by which electromotively coated polymer articles may be conveniently prepared.

Spray nozzle system using mask and method for fabricating touch screen for the same

The present invention relates to a spray nozzle system using a mask and a method for fabricating a touchscreen using the same. The spray nozzle system using a mask includes: a spray nozzle which discharges ink primarily atomized by collision with a gas; a substrate which is opposite to the spray nozzle, and onto which the ink discharged from the spray nozzle is shot; a mask which is arranged between the spray nozzle and the substrate and includes through parts on a moving path of the ink such that the ink discharged from the spray nozzle can pass through to be shot to the substrate; and a voltage apply unit which applies voltage to the spray nozzle such that the ink discharged from the spray nozzle can include electric charges, and which secondarily atomizes the ink discharged from the spray nozzle by generating an electric field between the substrate and the spray nozzle by the voltage applied to the spray nozzle. Therefore, the spray nozzle system using a mask can uniformly atomize ink to a fine size and can shot the atomized ink to the substrate accurately.

This invention provides a method of electrostatically applying a coating composition to dielectric materials that has a dielectric constant of less than 4.0. In this procedure, a positive charge is induced in a coating composition. The electrical material is electrically isolated, negatively charged, or both. The positively charged coating composition is sprayed onto the dielectric material. If the dielectric material is negatively charged, the method of the present invention further includes the phase of maintaining at least a portion of the negative charge on the dielectric material while the positively charged coating particles are sprayed onto it.
