  • Publication number: 20150051386
    Abstract: The invention is directed to a process for the continuous acetylation of wood elements. The process particularly combines a batchwise impregnation step, with a continuous reaction step. In order to realize this, a collection step is built-in, so as to allow batches of impregnated wood elements to be fed into a reactor in a continuous manner. Very high acetylation contents can be obtained, at a level that had not been achievable before in a continuous and non-catalyzed acetylation process.

  • Patent number: 8445072
    Abstract: A method of treating wooden parts is described in which a) the wooden parts are impregnated with an aqueous cyanamide solution and subsequently b) the impregnated wooden parts, where appropriate after drying, are subjected to a heat treatment of 130 to 250° C. Here it has surprisingly emerged that impregnation with cyanamide even in small amounts has a significantly positive influence on the performance properties of the treated wooden parts, such as high hardness, low water absorption and very good weathering stability, for example. Moreover, only small amounts of a toxicologically and environmentally unobjectionable impregnating agent are needed in order to obtain these advantageous properties.

  • Patent number: 8105635
    Abstract: The present invention relates to post-treatment compositions and methods useful for modifying the distribution of metal biocide(s) in biodegradable substrates such as wood, other cellulosic products, starch-based products, and the like that are vulnerable to decay due to insects, fungi, microbes, and the like. The compositions include complexing agents of moderate strength that are able to facilitate mobilization and redistribution of metal biocide(s) in substrates without undue leaching. The compositions can be used, for example, to redistribute the metal biocide(s) into depleted regions of a substrate by redistribution of metal biocide from other regions of the substrate. Post-treatment compositions that include additional metal biocide can also replenish these regions with the freshly supplied, additional biocide. Thus, the depleted regions can be restored by redistribution and/or replenishment mechanisms. Service life of substrates in the field benefits by these post-treatments as a consequence.

    Abstract: Preservative compositions for wood products are described. The compositions include at least one boron-containing material, such as but not limited to boric anhydride, and at least one silane-containing material, such as but not limited to methyltrichlorosilane. 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.

  • Publication number: 20110039110
    Abstract: A method of enhancing visual aspect stability in wooden substrates comprised of the steps of preparing a sealing composition by mixing thermosetting resins and hardener, applying said sealing composition onto the surface of a wooden substrate; and curing said polymer. The method may additionally comprise further steps of: scuffing or sanding the cured sealing layer, applying one or more topcoat composition, and curing said topcoat composition. Interior that comprises sealed wooden substrates with enhanced visual aspect stability produced by methods of the invention are also provided.
