In some embodiments, the water-repelling agent has an average molecular weight of about 220 to about 350 Daltons (solids portion). The water-repelling agent may be applied as a wax emulsion or in neat wax form. The present disclosure also relates to a method for manufacturing a wood composite as described above.Type: GrantFiled: March 31, 2009Date of Patent: June 10, 2014Assignee: Weyerhaeuser NR CompanyInventors: Jack G Winterowd, Travis E. Bjorkman, Erik M Parker

Patent number: 8722092Abstract: The present invention provides novel nanoscale cellulose particles and also a process for their production. The cellulose-based particles obtained have volume-averaged particle sizes of less than 300 nm. These nanoparticles are produced from amorphous cellulose or by amorphization of cellulose, optional subsequent hydrolysis and by input of energy into a water-containing medium after or during dispersion.Type: GrantFiled: August 8, 2008Date of Patent: May 13, 2014Assignee: Dow Global Technologies LLCInventors: Klaus Nachtkamp, Jürgen Engelhardt, Christa Krüger, Steffen Fischer, Manfred Pinnow, Kay Hettrich

Patent number: 8703847Abstract: The present invention is directed to a method for preparing a cellulose reactive adduct of polyvinylamide and a composition resulting from the method. The preparation of the cellulose reactive adduct is carried out close to a Critical Concentration defined herein. When the reaction is run close to this Critical Concentration, the risk of gelation is minimized, consumed glyoxal is maximized, and shelf live is enhanced. Additionally, the glyoxalated vinylamides of the present invention impart improved wet and dry strengthening efficiency to paper and paperboard when compared to adducts disclosed in previously described art.Type: GrantFiled: June 15, 2012Date of Patent: April 22, 2014Assignee: BASF SEInventor: Matthew D. Wright

Publication number: 20140107257Abstract: A flame retardant composition is produced by mixing a flammable organic material with an inorganic phosphorus-inorganic phosphoric oxyacid compound or its salts. The inorganic phosphorus-inorganic phosphoric oxyacid compounds are produced by reacting an inorganic phosphorus compound having a valence of 3-4 with an inorganic phosphorus oxyacid with a valence of 5. Carbonization auxiliaries, metal-containing compound having a carbonization acceleration effect, a comb-like polymer and a filler may be added with the flame retardant composition.Type: ApplicationFiled: October 12, 2012Publication date: April 17, 2014Inventor: David H.
