Abstract
This invention discloses adhesive compositions useful for providing cohesive strength to particles, for example a mat of wood particles produced while making particleboard prior to curing. The adhesive compositions has a) one or more biopolymers and b) one or more monomers or oligomers. An oligomer may have a degree of polymerization of 4 or less. The weight ratio of the monomer/oligomer to the biopolymer is optionally between 30:70 and 80:20. Optionally, the adhesive compositions may be combined with an isocyanate. The adhesive composition may be used to make no added formaldehyde wood composites such as particleboard.
