Optionally, at least one solvent, such as tetrahydrofuran, pentane, or water, may also be employed in the compositions. The compositions impart protection to the treated wood products, especially damage caused by exposure to water and insects.

  • Patent number: 7258826
    Abstract: The manufacture of zinc borate and calcium borate powders in a water slurry and drying those powders in a controlled manner such as to leave a desired residual of moisture content uniformly dispersed throughout the product produces a low dust, flowable material. This low dust material results in environmental and economic benefits to users of these preservative borates. The preferred amount of residual moisture is from 2 to 10 percent.

  • Patent number: 7238654
    Abstract: The invention relates to a compatibilizing dispersant used in a slurry composition comprising a strongly cationic component and a strongly anionic component. More specifically, the invention relates to stable aqueous slurries comprising suspended particles of sparingly soluble salts, oxide, and/or hydroxides of copper and/or zinc. The slurry further comprises a quaternary amine compound present in a biocidally effective amount when the slurry is used in a manner that provides the sparingly soluble copper and/or zinc containing particles in a biocidally effective amount. The slurry further comprises an effective amount of a dispersant having a large non-ionic component.

  • Patent number: 7211293
    Abstract: A closed-loop system and process is used for applying fire retardant chemicals to fibers. Fibers are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. Recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.
