  • Patent number: 8969471
    Abstract: A process for the preparation of stable aqueous polycarbodiimide dispersions to be used as cross-linking agents, in which initially an isocyanate functional polycarbodiimide is prepared from a polyisocyanate and a mono- or polyisocyanate which contains a hydrophobic group. Thereafter the polycarbodiimide chain is capped and/or extended by reaction of the isocyanate functions or a part thereof with a hydrophilic amine- or hydroxy functional compound and of the remaining isocyanate functions with an amine- or hydroxy functional compound which contains hydrophobic groups, after which the obtained product is dispersed in water and the pH is adjusted to 9-14. The hydrophobic groups are hydrocarbons with 4-25 carbon atoms, fluorinated hydrocarbons, silicone functional hydrocarbons or polysilicones. Further, the invention relates to a coating mixture in which the polycarbodiimide dispersion is used as cross-linking agent and to the cured material obtained with the coating mixture.

  • Patent number: 7223455
    Abstract: A duct board or duct liner comprises: an insulating layer formed from fibrous material bound with a resin binder, an outer facing layer adhered to an outer surface of the insulating layer, and a water repellant mat facing adhered to an interior surface of the insulating layer opposite the outer surface to form a duct board material. The mat facing provides sufficient water repellency to repel a mixture of about 40% isopropanol and about 60% water. The duct board or duct liner material may be formed into a tubular shape capable of conducting air, with the mat facing on the interior of the tubular shape.

  • Patent number: 7008887
    Abstract: The present invention relates to cellulosic substrates with reduced absorbent capacity having the capability to wick liquids, as well as to methods of manufacturing such cellulosic substrates. The cellulosic substrates provided by the present invention comprise an inside and an outside connected to the inside. The inside comprises cellulosic fibers and has a reduced absorbent capacity, and the outside comprises cellulosic fibers. The outside may have a reduced absorbent capacity and may have an absorbent capacity higher than the inside. The cellulosic substrate is capable of wicking liquid contacting the inside of the substrate to the outside of the substrate.

  • Patent number: 6972145
    Abstract: The present invention provides coating materials (14), insulation-containing building material products bearing the materials and methods for applying the coatings to the building material products. The coating materials (14) possess one-way “breathability” characteristics with respect to water and aqueous solutions. That is, the coatings are essentially impermeable to liquid water and permeable to water vapor. Vapor from water insulation coated by the material may thus pass through the coating, whereas liquid water is effectively prevented from passing through the coating and entering the insulation.

  • Patent number: 6924329
    Abstract: A water- and oil-repellent, antistatic composition comprises (a) at least one polymeric salt consisting of (i) at least one cation having at least one polyoxyalkylene moiety bonded to a cationic nitrogen center, and (ii) at least one weakly coordinating anion, the conjugate acid of the anion having an acidity greater than or equal to that of a hydrocarbon sulfonic acid; (b) at least one fluorochemical repellent; and (c) at least one insulating material. The composition exhibits good antistatic and repellency characteristics.

  • Patent number: 6897167
    Abstract: The thermal foot cover is an article of footwear to be worn when the wearer's foot is subjected to cold temperatures. The thermal foot cover has an upper cover portion attached to a bottom panel to define a cavity for insertion of a wearer's shoe-encased or boot-encased foot or a wearer's foot. The upper cover portion and the bottom panel are made from a material comprising an outer covering, a radiant barrier and a inner covering where the radiant barrier is sandwiched between the outer cover and the inner cover. The radiant barrier is the insulation system of the thermal foot cover, which reflects the wearer's body heat back inside the footwear and keeps the wearer's feet warm. The thermal foot cover is flexible, lightweight and readily washable due to the use of the radiant barrier as the insulation system.

  • Patent number: 6833335
    Abstract: A fabric having a unique combination of stain resistance, fluid barrier properties, aesthetic characteristics and drape ability is described, and a method of making such fabrics. The fabric includes a fabric substrate that has been treated with a low surface energy stain resist compound on at least one of its surfaces, and one or more layers secured to the other of its surfaces, with the layers providing the fabric with the unique combination of characteristics. In addition, the fabric is desirably provided with flame resisting and ultraviolet resisting characteristics, to enable it to be used as a seating material for transportation vehicles. Methods for making the fabric are also described.

  • Patent number: 6818253
    Abstract: A process for imparting durable water and oil repellency and durable soil release characteristics comprises the application of an aqueous mixture having a water repellent component such as a fluorocarbon polymer and a separate hydrophilic soil release polymer to a textile substrate, followed by a drying step. Optionally, a curing or thermosetting step may also be employed, if desired. This process is carried out in a preferred embodiment in a generally mild pH, which allows the process to be performed on a wide variety of textile substrates that may not be capable of withstanding more extreme pH values. Polyamides, aramids, polyesters, and poly/cotton substrates, when treated according to the present process, have all yielded improved performance with respect to durable water and oil repellency and durable soil release characteristics. A novel mixture or bath and novel treated substrates are also disclosed.
