Abstract: A method of manufacturing a wood board, comprising: applying a binder composition, notably in the form of an aqueous solution, to loose wood matter to provide resinated loose wood matter, wherein the binder composition consists of a binder composition prepared by combining reactants comprising at least 50% by dry weight reducing sugar reactant(s) and at least 5% by dry weight nitrogen-containing reactant(s); and arranging the resinated wood matter as a sheet of loosely arranged resinated wood matter; and subjecting the sheet of loosely arranged resinated wood matter to heat and pressure to cure the binder composition and to form the wood board from the sheet of loosely arranged resinated wood; wherein the nitrogen-containing reactant(s) comprise TPTA triprimary triamine(s), notably wherein the nitrogen-containing reactant(s) comprise at least 5% by dry weight of TPTA triprimary triamine(s).

Abstract: A method of manufacturing a wood board, comprising:



applying a binder composition, notably in the form of an aqueous solution, to loose wood matter to provide resinated loose wood matter, wherein the binder composition consists of a binder composition prepared by combining reactants comprising at least 50% by dry weight reducing sugar reactant(s) and at least 5% by dry weight nitrogen-containing reactant(s); and
arranging the resinated wood matter as a sheet of loosely arranged resinated wood matter; and
subjecting the sheet of loosely arranged resinated wood matter to heat and pressure to cure the binder composition and to form the wood board from the sheet of loosely arranged resinated wood;
wherein the nitrogen-containing reactant(s) comprise TPTA triprimary triamine(s), notably wherein the nitrogen-containing reactant(s) comprise at least 5% by dry weight of TPTA triprimary triamine(s).
