  • Binders containing an aldehyde-based resin and an isocyanate-based resin and methods for making composite lignocellulose products therefrom
    Patent number: 10889716
    Abstract: Binders, resinated furnishes, and methods for making composite lignocellulose products therefrom. The binder can include about 70 wt % to about 99.7 wt % of an aldehyde-based resin, about 0.3 wt % to about 30 wt % of an isocyanate-based resin, about 10 wt % to about 63 wt % of an extender, and about 145 wt % to about 230 wt % of water, where all weight percent values are based on a combined solids weight of the aldehyde-based resin and the isocyanate-based resin. The binder has a long pot life and can be used with lignocellulose substrates having a water content of 10 wt % or more.
