Methods for making lignocellulose containing composite products

A method for making a composite product, comprising:

• combining a plurality of lignocellulose substrates, a free radical precursor, and a polyphenolic material to produce a mixture, wherein the polyphenolic material is in a solid form when combined to produce the mixture;
• and
• heating the mixture to produce a composite product.

The method of claim 15, further comprising:

• 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;
• and then
• 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.

A composite product, comprising:

• an at least partially cured composition having a density of less than 1 g/cm3 and an internal bond strength of at least 0.35 MPa, wherein the composition, prior to curing, comprises a plurality of lignocellulose substrates, a free radical precursor, and a polyphenolic material, wherein the polyphenolic material is in a liquid form, a solid form, or both when combined with the plurality of lignocellulose substrates and the free radical precursor.
