Abstract
Methods for making composite products are provided. In at least one specific embodiment, the method can include combining a plurality of lignocellulose substrates, a free radical precursor, and a polyphenolic material to produce a mixture. The polyphenolic material can be in a liquid form, a solid form, or both when combined to produce the mixture. The method can also include maintaining the mixture at a temperature of less than 60° C. for at least 10 minutes while retaining at least 11 wt % of the free radical precursor charged to the mixture. The mixture can also include heating the mixture comprising at least 11 wt % of the free radical precursors charged to the mixture to a temperature of at least 60° C. to about 300° C. to produce a composite product.
