b) forming a resinated mat comprising the resinated wood particles arranged in the form of a mat of loosely arranged resinated wood particles; and c) forming a wood particle board by curing the binder composition while subjecting the resinated mat to pressure; wherein the binder composition comprises 0.1-25 wt. % of at least one non-carbohydrate polyhydroxy component comprising a viscosity at 20° C. of 10-10,000 cP for reducing or eliminating resinated wood particle clumping. ### Claim 2 (depends on 1) The method of claim 1, wherein the at least one non-carbohydrate polyhydroxy component is selected from the group consisting of glycerol, a polyalkylene glycol, polyethylene glycol, polypropylene glycol, trimethylolpropane, pentaerythritol, polyvinyl alcohol, partially hydrolyzed polyvinyl acetate, fully hydrolyzed polyvinyl acetate and mixtures thereof. ### Claim 3 (depends on 1) The method of claim 1, wherein the binder composition comprises an aqueous binder composition selected from an aqueous solution or dispersion comprising 40-95 wt. % solids, based on the total weight of the aqueous binder composition. ### Claim 4 (depends on 1) The method of claim 1, wherein the at least one non-carbohydrate polyhydroxy component comprises 1-20 wt. % of the binder composition. ### Claim 5 (depends on 1) The method of claim 1, wherein the binder composition comprises at least 30% by dry weight of a carbohydrate reactant. ### Claim 6 (depends on 1) The method of claim 1, wherein the binder composition comprises (a) at least one reducing sugar reactant and at least one nitrogen-containing reactant; and/or (b) at least one curable reaction product of at least one reducing sugar reactant and at least one nitrogen-containing reactant; wherein the combined weight of (a) and (b) comprises at least 30% by dry weight of the binder composition. ### Claim 7 (depends on 6) The method of claim 6, wherein the at least one reducing sugar reactant is selected from the group consisting of monosaccharides, disaccharides, polysaccharides and combinations thereof. ### Claim 8 (depends on 6) The method of claim 6, wherein the at least one nitrogen-containing reactant is selected from the group consisting of NH3, an inorganic amine, an organic amine comprising at least one primary amine group, a salt thereof and combinations thereof. ### Claim 9 (depends on 6) The method of claim 6, wherein the at least one nitrogen-containing reactant comprises a polyamine having the general chemical structure H2N—Q—NH2, wherein Q is an alkanediyl selected from the group consisting of a —C2—C24— group, a C6 alkanediyl group, a cycloalkanediyl group, a cyclohexanediyl group, a cyclopentanediyl group, a cyclobutanediyl group, a heteroalkanediyl group, a cycloheteroalkanediyl group, chemically substituted variants thereof and combinations thereof. ### Claim 10 (depends on 9) The method of claim 9, wherein the polyamine is selected from a polyether-polyamine, a polymeric polyamine and combinations thereof. ### Claim 11 (depends on 1) A wood particle board produced in accordance with the method of claim 1. ### Claim 12 (depends on 11) The wood particle board of claim 11, comprising wood particles held together by a cured, thermoset binder, wherein the wood particle board comprises at least 1-20 wt. % of at least one non-carbohydrate polyhydroxy component. ### Claim 13 (depends on 11) The wood particle board of claim 11, comprising a multilayer wood particle board comprising wood particles held together by a cured, thermoset binder, wherein at least one layer of the wood particle board comprises at least 1-20 wt. % of at least one non-carbohydrate polyhydroxy component. ### Claim 14 (depends on 1) The method of claim 1, wherein the at least one non-carbohydrate polyhydroxy component comprises 2-18 wt. % of the binder composition. ### Claim 15 (depends on 1) The method of claim 1, wherein the at least one non-carbohydrate polyhydroxy component comprises 5-10 wt. % of the binder composition. ### Claim 16 (depends on 6) The method of claim 6, wherein the polyamine is selected from 1,6-diaminohexane (hexamethylenediamine (HMDA)), 1,5-diamino-2-methylpentane (2-methyl-pentamethylenediamine) and combinations thereof. ### Claim 17 (depends on 6) The method of claim 6, wherein the at least one nitrogen-containing reactant comprises a polyamine having the general chemical structure H2N—Q—NH2, wherein Q is a divalent benzyl radical. ### Claim 18 (depends on 1) The method of claim 1, wherein the at least one non-carbohydrate polyhydroxy component comprises a viscosity at 20° C. of 100-5,000 cP.
