Biobased adhesives and non-conventional bonding

Abstract

Biobased adhesives fall into several major classes based upon their chemical structures. Starches are used in large volume, especially in the paper products industries, but cellulosics generally do not have the strength and water resistance needed for most wood products. Several authors have covered cellulosics adhesives (Baumann and Conner 2002, Pizzi 2006). However carbohydrate adhesives have not been used in wood bonding and they will not be discussed further here. Biobased adhesive bonding methods covered in this section, include proteins, lignins, tannins, as well as no added adhesive systems. Also not covered are biomass-based adhesive modifiers including fillers like nut shell flours and extenders like wheat gluten.
