  • Patent number: 7728096
    Abstract: The present invention is an adhesive suitable for use in the production of engineered wood products, said adhesive comprised of an aromatic diisocyanate (99.0-10.0 parts by mass) and an aromatic petroleum distillate (1.0-90.0 parts by mass) with low volatility. The adhesive composition may result in improved coverage or distribution on the outer surface of raw materials, such as strands, particles, flakes, fibers, or veneer.

  • Publication number: 20100104746
    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: 20030145541
    Abstract: A protective end cap adapted to engage the distal end of a wood plank. The protective end cap may include a spine and tapered sides extending from either side of the spine. Alternatively or additionally, the protective end cap may have a generally concave curvature along a lengthwise axis of the elongate body. The protective end cap may include an internal surface formed to contiguously engage the external surface of the distal end of the wood planks. Furthermore, the protective end cap may have an internal diameter that gradually increases as the sides extend from the spine. A wood plank including a protective end cap and a method for protecting a wood plank from damage by securing an end cap to the wood plank are likewise disclosed.

  • Patent number: 6429257
    Abstract: A mixture, casting system and method for forming a polyurethane product. The mixture typically includes a slurry including an alcohol containing at least two hydroxyl groups, and calcium carbonate. Typically, the calcium carbonate is present in the slurry in a range of between about 40% and 70% by weight. The mixture also includes an isocyanate mixed into the slurry such that isocyanate forms between about 10% and 50% by weight of the resulting mixture, the remainder of the resulting mixture being slurry. The mixture also may include a chain extender, cross-linking agent, or polymerization catalyst.

  • Patent number: 6245842
    Abstract: A flame-intumescent coating is provided for a wood-based building product, the coating being adapted to expand to form an expanded coating when exposed to heat from a fire. The coating comprises a polymeric binder, at least one blowing agent dispersed in the binder, and at least one intumescent compound dispersed in the binder. The blowing agent and intumescent compound are adapted to expand the coating when the coating is exposed to heat from a fire. The polymeric binder is formed from a mixture including castor oil and an isocyanate, wherein the castor oil is present in the mixture in a quantity of 9-36% of the total weight of the coating. A flame-retardant building product is also provided.
