Abstract:
The present invention relates to a method for fabricating a new silver coating/nanoparticle scaffold that significantly enhances the luminescence of near-field fluorophores via the metal enhanced fluorescence phenomenon. The silver coating/nanoparticle scaffold can be used for numerous applications in metal-enhanced fluorescence.
Abstract:
A method for the application of at least two different powder coating layers to a substrate comprising the steps of application of a first powder coating layer followed by the application of a second powder coating layer, without any substantial curing of the first powder coating layer prior to the application of the second powder coating layer, followed by the simultaneous curing of the first powder coating layer and the second powder coating layer, wherein the first powder coating layer or the second powder coating layer comprises 1 to 10 weight % of a conductive component having a resistivity of below 5 Ωcm at a packing volume of ≦70%.
Abstract:
An electrostatic coating device comprising a nozzle section that discharges a liquid to a substrate, a counter electrode that is disposed in such a way as to face the nozzle section and supports the substrate and a power source device that applies a voltage between the nozzle section and the counter electrode further comprises an instantaneous stop circuit that selectively grounds the nozzle section. When the nozzle section is grounded by the instantaneous stop circuit, a charge remaining in the nozzle section goes to the ground and the charge remaining in the nozzle section disappears. For this reason, after the power source device is turned off, dripping of the liquid from the nozzle section can be completed as quickly as possible.
Abstract:
A process for coating a preform with a flux is provided, which comprises: preform pretreatment, powder preparation, coating, curing, and post treatment. The process has the advantages of uniform and stable coating, highly controllable coating thickness, strong binding force, being efficient and environmentally friendly, and low cost, thus being suitable for coating the surface of various preforms with a flux.

Abstract:
A light metal workpiece with enhanced surface protection. The workpiece comprises a metal or alloy matrix having an exposed surface. A corrosion resistant oxide layer is formed in at least a portion of the exposed surface using a micro-arc oxidation technique. A first coating is applied onto at least a portion of the oxide layer using an electro-coating technique and is configured to seal the oxide layer. A second coating is applied onto at least a portion of the first coating, the second coating comprising a powder coating material. An appearance coating may optionally be applied onto at least a portion of the second coating, wherein the appearance coating includes at least one of a base coat, a color coat, and a clear coat.
Abstract:
A novel Aromatic Thermosetting Copolyester (ATSP) can be processed into highly effective wear resistant coatings by blending with polytetrafluorethylene (PTFE) and other additives. Surface treatments/coatings are key to improving wear performance and durability in a wide array of applications. The problems associated with use of liquid lubricants, hard/soft coatings are well known but only modest progress has been achieved due to lack of research on new material systems. These coatings were fabricated and tested as highly effective wear resistant coatings by blending ATSP with PTFE and other tribologically beneficial additives. The main advantages of these polymeric-based coatings are their relatively low cost and simple substrate surface conditioning (i.e., no need for expensive surface preparation before coating).
Abstract:
The present disclosure describes compositions comprising an acrylic polymer binder and nano-particles less than about 100 nm that provide a hydrophobic or superhydrophobic coating that may also display oleophobicity. The coating composition may advantageously be prepared using VOC exempt compounds that are compatible with a variety of surface materials including many electronic components. In addition, the coating composition may also be rapidly dried rendering it useful for the rapid preparation of coated objects and surfaces in manufacturing/assembly line environments.
