A method of manufacturing a composite product, comprising: - applying a binder composition, notably in the form of an aqueous solution, to non or loosely assembled matter to provide resinated 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 matter to provide loosely arranged resinated matter; and - subjecting the loosely arranged resinated matter to heat and/or pressure to cure the binder composition and to form the composite product; - 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), the TPTA triprimary triamine(s) being organic compound(s) having three and only three amines, each of the amines being primary amines or salts thereof, selected from: a) triprimary triamine(s) having spacer groups between each of the three primary amines which consist of carbon chains; b) triprimary triamine(s) having spacer groups between each of the three primary amines wherein each spacer group has a spacer length which is less than or equal to 12 polyvalent atoms; and c) triprimary triamine(s) having a total number of polyvalent atoms which is less than or equal to 23. - applying a binder composition, notably in the form of an aqueous solution, to non or loosely assembled matter to provide resinated 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 matter to provide loosely arranged resinated matter; and - subjecting the loosely arranged resinated matter to heat and/or pressure to cure the binder composition and to form the composite product; - 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), the TPTA triprimary triamine(s) being organic compound(s) having three and only three amines, each of the amines being primary amines or salts thereof, selected from: a) triprimary triamine(s) having spacer groups between each of the three primary amines which consist of carbon chains; b) triprimary triamine(s) having spacer groups between each of the three primary amines wherein each spacer group has a spacer length which is less than or equal to 12 polyvalent atoms; and c) triprimary triamine(s) having a total number of polyvalent atoms which is less than or equal to 23. a) triprimary triamine(s) having spacer groups between each of the three primary amines which consist of carbon chains; b) triprimary triamine(s) having spacer groups between each of the three primary amines wherein each spacer group has a spacer length which is less than or equal to 12 polyvalent atoms; and c) triprimary triamine(s) having a total number of polyvalent atoms which is less than or equal to 23. <EOS>
