Abstract
In some examples, a method for making a composite product can include combining a plurality of lignocellulose substrates, one or more complexed metal catalysts, one or more complexing agents, and one or more oxidants to produce a lignocellulose binder mixture and heating the lignocellulose binder mixture to produce a composite product. The lignocellulose binder mixture can have a molar ratio of the complexing agent to the complexed metal catalyst of about 0.1 or greater.

A method for making a composite product, comprising:
- combining a plurality of lignocellulose substrates, a complexed metal catalyst, a complexing agent, and an oxidant to produce a lignocellulose binder mixture, wherein the lignocellulose binder mixture has a molar ratio of the complexing agent to the complexed metal catalyst of about 0.1 or greater;
- and
- heating the lignocellulose binder mixture to produce a composite product.
A method for making a composite product, comprising:
- combining a plurality of lignocellulose substrates, a complexed metal catalyst, a complexing agent, a polyphenolic material, and an oxidant to produce a lignocellulose binder mixture, wherein the lignocellulose binder mixture has a molar ratio of the complexing agent to the complexed metal catalyst of about 0.1 or greater;
- maintaining the lignocellulose binder mixture at a temperature of less than 60° C. for at least 10 min;
- and subsequently
- heating the lignocellulose binder mixture to a temperature of at least 60° C. to produce a composite product.
A composite product, comprising an at least partially cured lignocellulose binder mixture, wherein the lignocellulose binder mixture, prior to curing, comprises a plurality of lignocellulose substrates, a polyphenolic material, a complexed metal catalyst, a complexing agent, and an oxidant, and wherein the lignocellulose binder mixture has a molar ratio of the complexing agent to the complexed metal catalyst of about 0.1 or greater.
