  • Publication number: 20090191401
    Abstract: Magnetic receptive Paints and coatings have been developed to allow one to paint a wall with this coating and apply magnets to this surface. The further development of magnetic receptive coatings incorporates the use of multiple size particles giving the finished surface a smoother appearance and increasing the particle load in the dry mill surface. This is useful in the coating of substrates where the need to coat the thinnest possible coating on the surface of a substrate such as papers and films as well as painting on walls, gives you the highest magnetic receptive surface possible at the thinnest mill thickness of applied coating.

  • Patent number: 7473457
    Abstract: Disclosed herein is a back-grooved laminate wood flooring in which a wood veneer of high pressure resin impregnation laminate (WPL) is laminated on a base selected from a vinyl chloride (PVC) resin layer, on oriented strand board (OSB), a high-density fiberboard (HDF) and a waterproof plywood. More specifically, the back-grooved laminate wood flooring comprises a WPL (20), an adhesive layer (40) and a base (10) (a polyvinyl chloride resin layer, OSB, HDF or waterproof plywood) wherein the WPL (20) includes a base-reinforcing layer (24), a natural veneer layer (23), a resin-impregnated overlay layer (22) and a surface UV coating layer (21) layered in this order from the bottom. The back-grooved laminate wood flooring further exhibits excellent soundproofing performance.

  • Publication number: 20080311416
    Abstract: Embodiments of the present disclosure include paper coating compositions, coated paper and/or paperboard, and methods of forming coated paper and/or paperboard with the paper coating compositions. The embodiments of the paper coating compositions contain high levels of hollow polymeric pigment relative to other pigments used in the paper coating composition (e.g., inorganic pigments). The paper coating compositions can provide the coated paper and/or paperboard with a wide variety of desirable features (e.g., high gloss, good smoothness, improved stiffness), while minimizing compaction (i.e., permanent deformation) of the underlying base paper.

  • Patent number: 7452601
    Abstract: An oxygen scavenger composition includes mer units that have at least one cycloalkenyl group or functionality and, further, has mer units derived from isophthalic acid or terephthalic acid or certain derivatives thereof. The oxygen scavenger composition has been found to act as an oxygen scavenger under both ambient and refrigeration conditions, to be compatible with conventional film forming packaging materials, to inhibit undesirable oligomer formation and oxidation by-product formation, and to be readily formable and processable using conventional film forming equipment. A film and laminated product having said oxygen scavenger composition are also disclosed.

  • Patent number: 7449231
    Abstract: Disclosed herein is a UV surface-coated laminate wood flooring for an under-floor heating system comprising a back-grooved base, an adhesive layer and a printed wood veneer layer wherein the printed wood veneer layer is produced by impregnating and coating a low-basis weight printed paper with a thermoplastic or thermosetting resin, integrally forming the paper layer with a low-price reinforcing layer by pressing under high pressure, treating the surface of the paper layer with an acryl based primer, and coating the primer-treated paper layer with a solvent-free type UV coating paint, and wherein the back-grooved base and the printed wood veneer layer are adhered to each other by the adhesive layer.

  • Publication number: 20080261021
    Abstract: The specification pertains to a single or multiple coated printing sheet in particular but not exclusively for sheet-fed offset printing with an image receptive coating layer on a paper substrate. The printing sheet has the property that it can be printed in an offset printing process without spraying a fine powder, usually called offset powder or dust powder, on the sheet as it comes off the press to prevent the ink from transferring to the back side of the next sheet. Also irradiative (UV or IR) drying on the sheet fed press is not necessary and/or the use of overprint varnish is not required. In addition to that, unexpectedly short times until reprinting and converting can be achieved. Furthermore methods for making such a printing sheet and uses of such a printing sheet are disclosed.
