A method for making a composite product can include combining a plurality of lignocellulose substrates and a binder to produce a resinated furnish. The binder can be or include a polyphenolic compound, a free radical precursor, and an unsaturated compound having two or more unsaturated carbon-carbon bonds. At least one of the unsaturated carbon-carbon bonds is a pi-bond that is not conjugated with an aromatic moiety and is capable of free radical addition. The method can also include pressing the resinated furnish between at least two surfaces in a press, where at least one of the at least two surfaces can be a porous surface, and at least partially curing the binder in the resinated furnish to produce a composite product.
