Wood particle boards

A method of manufacturing a wood particle board comprising wood particles bound by a cured thermoset binder comprising:

• a) mixing wood particles with a binder composition having a dry weight comprising at least 40% by weight (wt. %) of the binder composition to produce resinated wood particles comprising wood particles coated with the binder composition;
• 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.
