  • Publication number: 20070074831
    Abstract: Systems and methods for treating raw materials for formation into a wood product are provided. The raw materials may be, for example, strands, flakes, particles, wafers, or the like. In an embodiment, a first dispensing device dispenses a first liquid component onto raw materials within a chamber. A second dispensing device dispenses a second liquid component onto the raw materials. When the raw materials are mixed together, the first and second liquid components interact to form a bonding agent.

  • Publication number: 20070022709
    Abstract: Systems for attaching a plurality of wood products are provided. In a first type of system, a first wood product has a first chemical compound applied to a surface of the first wood product. A second wood product has a second chemical compound applied to a surface of the second wood product. An adduct is formed when the first chemical compound contacts the second chemical compound wherein the first wood product becomes adhered to the second wood product. In a second type of system, a pressure sensitive and/or anaerobic adhesive is placed on at least one of the wood products prior to assembly. The compounds/adhesives have an open assembly time greater than or approximately equal to 24 hours.

  • Publication number: 20060286367
    Abstract: The barrier properties of a water soluble gas barrier material are improved if the material is blended with a nanoparticle calcium carbonate having a size of from 10 to 250 nanometers. The barrier material is on a substrate to provide a substrate with gas barrier properties. A layer of heat sealable material may be applied to the exposed surface of the barrier material. A method for making the barrier coated substrate is disclosed.
