Abstract

Adhesives are used all over the world to combine the materials together. Due to its extended usage environment conservation authorities emphasize the importance of reducing the volatile organic content in adhesive manufacturing processes. As a solution, researchers are focusing on water-based adhesives instead of adhesives based on organic solvents. The binders that can be dissolved in water are needed to develop such water-based adhesives. In this study the possibility of using tamarind seed powder as a binder was analyzed. Tamarind seed powder can be used to develop an effective water-based wood adhesive with characteristics compatible with commercial glues. By comparing viscosity, fixture time and bond strength, the minimum initial seed powder concentration for an effective glue was identified as 6.25 %(w/v). In terms of the cost, minimal usage of raw material gives an additional advantage. Therefore 6.25% was selected, as it was the glue with minimum seed powder concentration which showed the above parameters compatible with commercial glues. This will be a green light to adhesive industries to reduce human health hazards and environmental hazards. On the other hand, it will be one of the value addition processes for the tamarind seed waste.
