DEVELOPMENT OF DEFATTED SOY FLOUR AND CASEINBASED BIO ADHESIVES FOR WOOD JOINT

Abstract

Wood adhesives were made using defatted soy flour, casein, sodium hydroxide (NaOH) and ethylene diamine. These eco-friendly wood adhesives are used to substitute formaldehyde-derived adhesives in order to decrease formaldehyde and volatile organic compounds emissions from the adhesives that are utilised in plywood. The features of adhesively-glued wood joints in terms of performance such as tensile strength, water resistance and chemical resistance were gauged in this study. The results revealed that adhesives showing good performance and eco-friendly adhesive system was prepared for wood joints.
