Abstract

The fact that formaldehyde-based resins used as adhesives in the wood-based panel industry are produced from fossil sources and formaldehyde limits that are becoming more restrictive day by day have increased the focus on bio-based resin studies. Starch is one of the most preferred bioresources in biobased resin studies, thanks to its availability and suitable chemical structure. However, starch's poor water resistance, short shelf life, and high viscosity limit the use of starch-based resins. Many physical and chemical modification techniques have been studied to overcome starch's disadvantages, and the results have been reported. In this review, chemical modification techniques that will facilitate the use of starch as a resin in the wood-based panel industry are examined. Improved weaknesses of starch with applied chemical modifications have been reported. The results showed that with chemical modification techniques, starch is a potential candidate to compete with petrochemical-based adhesives and can play an important role in biobased wood resin development studies.
