At present, formaldehydebased adhesives such as urea formaldehyde (UF), melamine formaldehyde (MF), melamineurea formaldehyde (MUF) etc. are mostly used in woodbased panel industry because of their high reactivity, chemical versatility and economic competitiveness. However, formaldehydebased wood adhesives are produced from nonrenewable resources. Hence, there has been a growing interest in the development of environment friendly, economically competitive, biobased wood adhesives in order to meet woodbased panel industry requirements. In this study, as formaldehyde free adhesive, tannin and starchbased wood adhesive was synthesized. Citric acid and tartaric acid were used as hardener for the resin system. Solid content, viscosity and gel time analyzes of the prepared adhesive were performed in order to evaluate the adhesive processability. FTIR characterization technique was used to elucidate chemical structures of the cured adhesive samples. In order to evaluate the performance of the prepared biobased resin formulation, particleboards were produced in laboratory scale and mechanical, physical properties of the boards were investigated. Besides, formaldehyde contents of the boards were determined by using perforator method. The obtained results revealed that the developed biobased wood adhesive formulation can be a good potential candidate to use in woodbased panel industry with some developments.
