Abstract
An adhesive suitable for bonding wood is both heat curable and radio frequency (RF) curable. This adhesive is composed of an isocyanate-terminated prepolymer and hydrolyzed soy protein having a pH of at least about 9 and advantageously from about 9 to 11.5. The weight ratio of prepolymer to soy protein hydrolyzate ranges from about 70:30 to 90:10.
