Abstract:
The present invention relates to a method for applying hexagonal boron nitride to a rough surface, wherein it is intended for the boron nitride to be provided as a temperature-resistant lubricant of the surface. According to the invention, a pin composed of hexagonal boron nitride is rubbed with pressure over the rough surface, such that abraded boron nitride adheres to the surface.
Abstract:
A device for coating an exterior of an elongate object includes a housing structure with an elongate chamber having first and second opposite ends. A port communicates with the first end for receiving the elongate object and an outlet is located at the second end. An air supply passage and a coating material supply passage communicate with the elongate chamber. Pressurized air and coating material are adapted to enter the elongate chamber through the air supply passage and the coating material supply passage, respectively, to form a mist in the elongate chamber moving toward the outlet while coating the exterior of the object. A method of coating an exterior surface of the elongate object with the coating material includes holding the elongate object lengthwise in the elongate chamber, mixing the pressurized air and the coating material to form a mist, and coating the exterior surface while directing the mist around the exterior surface and toward the outlet of the elongate chamber.
Abstract:
A coating method for producing an electrically insulating coating on a bearing component, wherein, in a first step, a substance mixture comprising at least a) a silane and/or siloxane compound, b) a metal alcoholate, and c) PEEK and/or PTFE in the form of a dispersion is applied to the bearing component and, in a second step, is solidified on the component surface by means of a laser beam.
Abstract:
Disclosed is a method of manufacturing a finished cable by a process directed to reduce the amount of force required to install the cable. The process involves the extrusion of the cable's outer sheath and the incorporation of a pulling lubricant in connection with, and prior to the completion of, the extrusion to reduce the sheath's surface coefficient of friction as well as reduce the required force to pull the cable for installation. The conductor core is coated with an extruded plastic material with which an appropriate (in amount and type) pulling lubricant is initially combined with the plastic material prior to the formation of the sheath and in which the sheathed conductor core is thereafter cooled, the lubricant either migrating to and/or permeating the sheath to be available at the surface of the sheath at the time of the cable's installation. The preselected lubricant is disclosed as either combined with the plastic material during initial pelletization, or mixed with the plastic pellets prior to introduction of the mixture into the extruding head, or introduced into the extruding head at a separate location downstream from where the plastic material is introduced into the extruding head.
Abstract:
A superhydrophobic electromagnetic field shielding material includes a curable resin and a carbon material, the superhydrophobic electromagnetic field shielding material including at least two depression patterns on an exposed surface. The at least two depression patterns may include a first depression pattern including a plurality of grooves having a same shape and a second depression pattern including a plurality of grooves having a same shape. The carbon material may be about 3 wt % to about 20 wt % based on the total weight of the superhydrophobic electromagnetic field shielding material.
Abstract:
A process for fabricating oleophobic surface coatings to be deposited on a metal surface, such as the front-face or aperture plate of piezoelectric print heads and transfix rolls. The surface coatings are applied to the surface by electrochemical polymerization.
Abstract:
The present invention provides a method for the production of a superhydrophobic film, surface or material comprising the steps of: (i) providing a composition comprising a hydrophobic substance and a hydrophilic solvent, the hydrophilic solvent being a liquid at a temperature of 25° C. and atmospheric pressure; and (ii) spraying the composition towards a substrate for deposition of a solid residue onto the surface of the substrate for generation of the superhydrophobic film, surface or material; wherein the temperature of the composition is higher that the temperature of the substrate when carrying out step (ii). A composition, use of the composition and a substrate is also provided.
Abstract:
The present invention relates to the technical field of treated mineral filler products. The invention further relates to a process for preparing such treated mineral filler products, and to its preferred use in the field of plastic applications, and in particular polypropylene (PP)- or polyethylene (PE)-based breathable or extrusion coating film applications.
Abstract:
Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability, and are readily applied in coating processes. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.
Abstract:
A medical electrical lead body having an outer surface and including at least one lumen having an inner surface treated with a silane surface modifying agent to form a three-dimensional, densely cross-linked lubricious coating over at least a portion of the inner surface of the lumen. The outer surface of the lead body also may be similarly treated. The lubricious silane coating may reduce the coefficient of friction of the coated surface of the lead body by as much as 80% when compared to an uncoated surface. A reduction in the coefficient of friction may enhance the stringing efficiency of a conductor through the lead body lumen and may enhance its abrasion resistance.
