  • Patent number: 10119034
    Abstract: A crosslinking polyvinyl acetate (XPVAc or X-PVAc) adhesive is applied as a primer (i.e., a basecoat) or an exterior coat (i.e., a top coat) on a wood preservation product which is mainly treated with a water-based preservative. By sealing the exterior wood surfaces, the new coating system not only effectively prevents the leaching of the preservative by bonding and chelating with the unfixed preservative compounds or complexes at the surface layer, but it also significantly reduces surface aging of wood, maintains effective preservation functions, and provides a longer service life to the wood preservation product.

  • Patent number: 7482057
    Abstract: The present invention is directed to a lithographic method and apparatus for creating micrometer sub-micrometer patterns in a thin film coated on a substrate. The invention utilizes the self-formation of periodic, supramolecular pillar arrays (49) in a melt to form the patterns. The self-formation is induced by placing a plate or mask (35) a distance above the polymer films (33). The pillars bridge the plate and the mask, having a height equal to the plate-mask separation and preferably 2-7 times that of the film's initial thickness. If the surface of the mask has a protruding pattern, the pillar array is formed with the edge of the pillar array aligned to the boundary of the mask pattern.

  • Patent number: 7335409
    Abstract: The invention relates to a manufacturing method of a heat-sealable packaging material, a polymer-coated packaging material manufactured using the method, and a sealed package to be manufactured of the material. The packaging material comprises a fibre base, such as a packaging board (5), and an inner, extruded water vapour barrier layer (2, 9) on both sides, containing high-density polyethylene (HDPE), and an outer heat sealing layer (1, 10), the material of which is, for example, low-density polyethylene (LDPE). Further, polymeric oxygen barrier layers (7) can be incorporated in the packaging material, the material of the oxygen barrier layers being, for example, ethyl vinyl alcohol copolymer (EVOH) or polyamide (PA). With the HDPE layer, the permeation of water vapour is prevented to both directions, and the location of the extruded layers on both sides of the fibre base reduces the curling of the material.
