  • Patent number: 9682493
    Abstract: A method for treating a piece of wood impregnates the piece of wood with a water repellent, wherein the water repellent is solid at ambient temperatures. The method includes the steps of providing a piece of wood to be treated; heating the piece of wood for a predetermined period of time, the piece of wood being heated at a temperature A; subsequently immersing at least a portion of the piece of wood in a bath of liquefied water repellent, the bath being at a temperature B, for a predetermined period of time. Thereafter the piece of wood is removed from the bath and allowed to cool. The temperature A is above 100° C. and the temperature B is below 100° C. but above a liquefying point for the water repellent, and a differential between temperatures A and B is at least 60° C.

  • Publication number: 20130174758
    Abstract: A binder comprising a polymeric binder comprising the products of a carbohydrate reactant and organic acid is disclosed. The binder is useful for consolidating loosely assembled matter, such as fibers. Fibrous products comprising fibers in contact with a carbohydrate reactant and an organic acid are also disclosed. The binder composition may be cured to yield a fibrous product comprising fibers bound by a cross-linked polymer. Further disclosed are methods for binding fibers with the carbohydrate based binder using an organic acid.

  • Publication number: 20130149456
    Abstract: The present invention provides aqueous self-inspecting wet coatings or films that dry to form translucent to clear weather-resistive barriers on a substrate, preferably a building substrate such as sheathing. The coatings comprise, as a wet film, one or more aqueous emulsion or dispersion polymer that can form a film in use conditions and less than 6% pigment volume concentration (% PVC), of one or more opacifier, one or more extender in amounts up to critical % pigment volume concentration (CPVC), optionally, one or more pigment, and substantially no void, hollow core, or hollow sphere containing pigment. The coatings or films enable one to apply the correct amount of coating to make a weather barrier that dries to a see-through coating or film.

  • Patent number: 8460758
    Abstract: This invention is directed to a process for the preparation of a crosslinker composition, comprising the steps of providing a mixture of an aliphatic alcohol A having at least one hydroxyl group and from 1 to 10 carbon atoms, with at least one multifunctional aldehyde C having at least two aldehyde groups —CHO to form a mixture AC, heating the mixture AC to convert at least a part of the multifunctional aldehyde C to its hemiacetal or to its acetal to form a mixture (AC)?, adding to the mixture (AC)? least one cyclic urea U or the educts to produce the said cyclic urea U in situ, which cyclic urea U has at least one unsubstituted >NH group, and reacting the mixture thus obtained to form a chemical bond between the nitrogen atom of the at least one unsubstituted >NH group of the at least one cyclic urea U5 and the carbon atom of the least one aldehyde group —CHO of the multifunctional aldehyde C, and coating compositions comprising the said crosslinker composition.

  • Patent number: 8460759
    Abstract: The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.
