Development of Cassava-Based Bio-Adhesive Using Polyvinyl Acetate (P.V.A.) for Engineered Wood Products Manufacturing

Adhesives are glue substances that serve as a binder which holds up materials together that is are able to make things adhere or stick together without deformation or failure through a process called adhesion (Baumann and Conner, 2003). Adhesives are categorized as either natural or synthetic. Natural adhesives include animal glues, casein glues, natural gums and resins, sodium silicates and vegetable glues. Vegetable glues are starch-based and are made from starches and dextrin (Kennedy, 2013). Starch has several advantages as a raw material in the production of adhesives, including: renewability, biodegradability, abundance, relatively cheap and affordability (Agboola, et al., 2010) and can also be used to produce diverse products as food, paper, textiles, beverages, confectionery, pharmaceuticals, and building materials (FAO, 2010).
