POLYMERIZATION-ENHANCING COMPOSITION FOR UREA-FORMALDEHYDE RESINS, METHOD OF MANUFACTURE, METHOD OF USE, AND ARTICLES FORMED THEREFROM |
摘要 |
<p>An aqueous reaction product of a composition that 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 2 to about 6, and urea. A curable urea/formaldehyde resin composition may contain a curable urea/formaldehyde resin and the foregoing composition, and may be made by combining the resin with the composition. A reconstituted wood product may be made by combining particulate lignocellulosic material with the foregoing curable resin, and curing the resin. Optionally, a reconstituted wood panel may contain a particulate lignocellulosic material and a binder composition comprising the cured product of curable resin and the aforesaid aqueous reaction product. A concentrate for forming a polymerization enhancing composition is also disclosed.</p> |
