Methods and processes for depositing a fire resistant barrier on a construction material involve coating exposed webbing of, for instance, an I-joist with a fire-resistant material using a wetting layer and a thickening layer. A time period between depositing the wetting layer and thickening layer is controlled to facilitate complete wetting of the exposed webbing. Filler such as fiberglass may be included in the thickening layer. The wetting and thickening layers may be deposited on the webbing in the same application. The construction material, such as the I-joist, may then be subjected to a curing treatment and additional curing period followed by coating the second side using a similar methodology.

A system for inspecting an interior surface of a girth weld region of a pipeline includes a robot that includes a scanner mounted on a carriage for scanning the interior surface of the girth weld region to generate surface profile data. A profile analyzer receives the surface profile data and outputs an indication of whether the interior surface of the girth weld region is suitable for being coated. In some embodiments, an imaging system captures images of the girth weld region as it is being scanned. In a method of coating the girth weld regions of a pipeline, the images of a girth weld region found to be unsuitable for being coated based on the scanning data are used to certify whether the girth weld region is suitable for being coated.

A method for applying a polymer coating to a substrate wherein the resultant layer of polymer on the substrate has a substantial thickness. A mixture of polymer material, including reactor bead polymer and ground polymer, may be used in a powder coating process to achieve thicker polymer layers.

A textured release sheet includes a substrate, which has been electron beam treated, including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

A method of providing an anticorrosive coating includes applying a first curable liquid layer to the associated substrate, the first layer having a thickness of at least about 100 micrometers, wherein the first layer includes at least one polymer or at least one monomer, quasi-one-dimensional particles or quasi-two-dimensional particles, sacrificial metal particles, and a solvent, wherein a percolation threshold of the particles is not reached in the presence of the solvent, wherein the percolation threshold of the particles is reached when between about 1% and about 20% of the solvent evaporates, applying a second curable liquid layer having a thickness of at least 100 micrometers on the top of the first layer after the percolation threshold of the particles is reached and viscosity of the first layer increases more than 50%, and allowing the first layer and the second layer to cure simultaneously.

A method for processing a raw workpiece into a final workpiece is described, wherein the raw workpiece includes a metallic structure including silicon particles dispersed therein. The raw workpiece is fabricated employing an additive manufacturing process, in one embodiment. The method includes heat-treating the raw workpiece to produce an intermediate workpiece, wherein the heat-treating includes subjecting the raw workpiece to a first temperature environment for a time period to produce an intermediate workpiece to form agglomerated silicon particles, wherein the agglomerated silicon particles are disposed on a surface of the raw workpiece. The method further includes removing the agglomerated silicon particles that are disposed on the surface of the intermediate workpiece.

Methods for producing layered structures that include a conductive polymeric layer and a dielectric polymeric layer. The dielectric polymeric layer can be formed by curing a first volume of a dielectric polymeric material. A second volume of the dielectric polymeric material is doped with conductive particulates to yield a conductive polymeric material, which is then partially cured and solvated to create a conductive polymeric paste. The paste is applied to a surface of the dielectric polymeric layer, dried, and cured to form a conductive polymeric layer on the pre-strained dielectric polymeric layer yielding a layered structure that includes the conductive polymeric layer and the dielectric polymeric layer. A pre-strain is induced in the dielectric polymeric material by contacting a chemical thereto that causes swelling therein.

In a method and a device for producing a powder coating melt, firstly a first powder coating melt is produced from a powder coating premix by means of a screw machine. Powder coating particles are supplied to the first powder coating melt. Then a second powder coating melt is produced by mixing the first powder coating melt and the powder coating particles by means of the screw machine. This allows a simple, gentle and efficient recycling of powder coating particles, in particular of so-called off-spec powder coating particles.
