Abstract:
Methods for supplying one or more vapors, under reduced pressure, to an environment are provided. The vapor may comprise at least one polymerizable component. In some cases, at least two components may be combined to form the vapor. The components may be provided as separate vapor streams, which may be combined and homogenized. Methods of the invention may also be useful in the deposition of materials on the surface of a substrate. In some cases, the material may form a layer, such as a polymer layer, on the surface of a substrate. The present invention may be useful in applications that require the formation of homogeneous films on the surface of a substrate.
Abstract:
The present invention relates to a process for making electrostatic charge dissipative material comprising the following steps: (a) optionally pretreating a substrate in a plasma field; (b) flash evaporating at least one monomer and at least one hygroscopic additive into a vacuum chamber to produce a vapor; (c) condensing the vapor on the substrate to produce a film of the monomer and the hygroscopic additive coating on the substrate; and (d) curing the monomer of the film to produce a polymeric layer containing hygroscopic additive on the substrate; wherein the condensing step is carried out under vapor-density and residence-time conditions that limit the polymeric layer to a maximum thickness of about 3.0 μm. The electrostatic charge dissipative material can be used to protect electrostatic sensitive electronic components.
Abstract:
The present disclosure features processes and equipment for forming a variety of textured materials, including both release webs, and finished products such as flooring materials, wall coverings, textured laminates and the like. The processes described herein allow curing radiation to be passed through a texturing medium, rather than through the substrate to which the curable material is applied.
Abstract:
A method of creating a pigmented image on a monument stone substrate includes positioning the stone relative to a laser engraving apparatus, masking the stone substrate in an image area in which the image is to be created with a first mask layer, operating the laser engraving apparatus in a pattern over the masked area at a sufficient power level to burn through the mask and pit the stone substrate with a first set of pits, applying a first layer of pigment over the image area to any remaining first mask layer in the image area and to the first set of pits, curing the first layer of pigment and removing any remaining first mask layer. Additional colors or pigment layers can be added by repeating the masking, burning and applying steps, and the final such step can be a dithered image, followed by an edge defining cutting step in which the border of the image is defined. All pigment layers are rooted in the stone. The final pigmented image is preserved with protective coatings.

[Object] There are provided a fluorocarbon resin composite having improved abrasion resistance while nonadhesiveness, which is a feature of a fluorocarbon resin, is maintained, cookware, and a roller and a belt for use in office automation equipment.[Solving Means] A fluorocarbon resin composite includes a fluorocarbon resin layer on a base, in which a fluorocarbon resin constituting the fluorocarbon resin layer is crosslinked by electron beam irradiation, and the base has a desired shape obtained by machining. The fluorocarbon resin is composed of a tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer, polytetrafluoroethylene, or a mixture of the tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer and polytetrafluoroethylene. A fluorocarbon resin composite, cookware, and a roller and a belt for use in office automation equipment are each produced by applying an uncrosslinked fluorocarbon resin on a base, subjecting the fluorocarbon resin to electron beam irradiation in a low-oxygen atmosphere to crosslink the fluorocarbon resin while the temperature of the fluorocarbon resin is maintained at a temperature equal to or higher than the melting point of the fluorocarbon resin, and machining the base into a desired shape. There is also provided methods for producing them.

Abstract:
Surface covering components that include a topcoat layer with different gloss levels in various regions on the top coat layer, and methods of manufacturing such surface covering components, are disclosed. The surface covering components include a coating layer that includes regions that have a relatively higher gloss, and regions with a relatively lower gloss. The differential gloss is provided by coating a substrate with a UV-curable coating composition, subjecting a first region of the surface coating to polymerization under a first set of conditions, and subjecting a second region of the surface coating to polymerization under a second set of conditions. The UV-curable coating compositions include UV-curable components and one or more flatting agents. The different polymerization conditions involve applying various photoinitiators, thermal initiators and/or cure altering agents to some regions of the coated substrate, and not applying these components to other regions of the substrate. The components are applied in the form of a pattern. Regions in contact with these components are cured at different rates in one step or in different steps, for example, sequential UV and EB irradiation or UV irradiation at different wavelengths and/or exposure times. The resulting surface coverings and surface covering substrates have differential gloss in register with the printed and/or sprayed patterns.

A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder is described. The process in accordance with one aspect of the invention includes introducing primary raw materials including a non-thermoplastic elastomer into a feeding section of the modified planetary roller extruder, conveying the raw materials from the feeding section to a compounding section of the modified planetary roller extruder, continuously mixing the primary raw materials in the compounding section to produce a homogeneous adhesive composition. The adhesive composition may be applied to a web-form material. The compounding section of the modified planetary roller extruder includes a main spindle surrounded by and intermeshed with a plurality of planetary spindles at least one of which is a double transversal mixing spindle having a plurality of back-cut helical flights.
