Abstract
A binder used for manufacturing a composite product is prepared by combining i) Maillard reactants selected from: reducing sugar reactant(s) and nitrogen-containing reactant(s); curable reaction product(s) of reducing sugar reactant(s) and nitrogen-containing reactant(s); and combinations thereof; and ii) a resin; reactants of a resin; and combinations thereof.
Claims12
A method of manufacturing a composite product comprising:
- preparing a binder composition in the form of an aqueous solution, which comprises combining:
- i) Maillard reactants;
- ii) a composition selected from a resin, reactants of the resin, and combinations thereof;
- and water;
- wherein the i) Maillard reactants are selected from:
- one or more reducing sugar reactants and one or more nitrogen-containing reactants;
- one or more curable reaction products of the one or more reducing sugar reactants and the one or more nitrogen-containing reactants;
- and combinations thereof;
- wherein the one or more nitrogen-containing reactants are polyprimary polyamines which are organic compounds having two or more primary amines;
- wherein the binder composition comprises at least 50 wt % by dry weight of ii) the composition selected from a resin, reactants of a resin, and combinations thereof;
- applying the binder composition to non-assembled or loosely assembled matter to provide resinated matter;
- arranging the resinated matter to provide loosely arranged resinated matter;
- and
- subjecting the loosely arranged resinated matter to heat and/or pressure to cure the binder composition and to form the composite product.
