UNITARY MAT HAVING INCREASED GREEN STRENGTH AND METHOD OF FORMING THE SAME

A unitary mat includes a plurality of lignocellulosic particles and an adhesive chosen from an isocyanate， phenol formaldehyde， polyamino amido epichlorohydrin， and combinations thereof. The adhesive is present in an amount of from about 1 to about 10 percent by weight based on 100 parts by weight of dry lignocellulosic particles. The unitary mat also includes a proteinaceous powder having a protein dispersibility index of from about 1 to about 90 and present in an amount of from about 0.5 to about 10 percent by weight based on 100 parts by weight of dry lignocellulosic particles， and an aqueous diluent present in an amount of from about 0.5 to about 10 percent by weight based on 100 parts by weight of dry lignocellulosic particles. The unitary mat may also have a green strength tack test result of greater than 3 inches.
