Abstract:
Binders, methods for making same, and methods for making composite lignocellulose products therefrom. The binder can include about 30 wt % to about 40 wt % of solids that include a urea-modified aldehyde-based resin; about 0.1 wt % to about 3 wt % of solids that include an isocyanate-based resin; about 0.1 wt % to about 12 wt % of an extender; and about 50 wt % to about 62 wt % of water, where all weight percent values are based on a total weight of the binder. The binder can have a sodium hydroxide equivalent weight alkalinity of about 3 wt % to about 9 wt %.
