摘要

The aqueous reaction product of a composition, resin composition curable urea / formaldeu00ecdo, methods for manufacturing the same, and for the manufacture of a wood product reconstituu00ecda, wood panel, and reconstituu00ecda,Concentrate for the formation of an intensifier composition of an aqueous polymerization reaction product composition may consist essentially of a source of an acid having a pKa in water of about 2 to about 8, a source of a base having a PKB in water of about D. And 2 to about 6, and urea.A resin composition curable urea / formaldehyde resin may contain a curable urea / formaldehyde and the previous composition, and can be produced by the combination of the resin with the composition. A reconstituted wood product can be produced by combination of Particulate lignocellulosic material with the curable resin and curing the resin above.Optionally, a reconstituted wood panel may contain a particulate lignocellulosic material and a binder composition comprising the cured product of the resin curable reaction product and the aqueous mentioned previously.A concentrate to form a composition may consist essentially of polymerization intensifier of an acid source previously said, a source of base previously told, and urea.
