  • Publication number: 20110048280
    Abstract: The present invention provides an improved method of producing a stable acid denatured soy/urea adhesive having improved wet and dry strengths, with more efficient production and lower production costs. The method comprises combining urea with soy flour that has been acid treated until denatured and substantially free from urease activity. The soy flour is preferably lowered to a pH of 2.0 to 4.0 for at least 1 minute. Optionally, the method may also include adding a crosslinking agent, diluent or both to the soy flour/urea adhesive and/or adding an emulsified or dispersed polymer. Adhesives and dispersions prepared according to the methods of this invention offer increased stability and strength properties.
