ENGINEERED WOOD ADHESIVES AND ENGINEERED WOOD THEREFROM

According to various examples of the present disclosure, an engineered wood precursor mixture includes a plurality of wood substrates and a binder reaction mixture present in a range of from 3 parts to 25 parts per 100 parts of the dry weight of the plurality of wood substrates. The binder composition includes an aqueous portion. The aqueous portion includes a carbohydrate-containing component in a range of from 2 wt% to 85 wt% based on a dry weight of the binder reaction mixture. The carbohydrate-containing component includes glucose, fructose, or a mixture thereof. The combined wt% of glucose, fructose, or mixture thereof in the carbohydrate-containing component is at least 60 wt%. The aqueous portion further includes 0.1 wt% to 10 wt% sodium trimetaphosphate based on a dry weight of the binder reaction mixture.
