Adhesive Binders are binders for paper coating compositions. The modified soy protein has found extensive use as an adhesive binder in paper coating compositions. They are typically prepared from isolated soy protein extracted from oil free soybean flakes in an alkaline solution and recovered by is electric precipitation. The recovered soy protein is then typically modified by hydrolysis and other chemical treatment to prepare a protein adhesive material suitable for use as a binder in paper coating compositions. These binders find usage in the paper coating industry. These high solids adhesive binder solutions can be prepared both using cold water and using water which has been heated.
