Get PDFPolyurethanes (PU) have been promising polymeric materials with many applications, including adhesives. Projecting an estimated revenue from 42.8 billion by 2026. However, a large number of PU adhesives are sourced from petroleum products. Therefore, to lower the dependence on non-renewable resources and provide sustainable and affordable alternatives. In this work will synthesize bio-based adhesives of polyurethane from modified castor oil-based polyol. Generally, polyurethane reaction depends on the properties of polyol and isocyanates. The most important aspect of these reactions is the OH number of the polyol, which is responsible for the crosslinking and bonding strength of the adhesives. Therefore, to increase the OH value and provide a better reaction platform, an external bio-based crosslinker in the form of tannic acid is to be incorporated and characterize the improvement in the chemical and mechanical properties of the adhesives. The same was reflected in the mechanical strength test, in which the tensile of the adhesive increased from 3.71 to 6.05 MPa for the sample without any mass loadings of tannic acid to 10 wt % tannic acid correspondingly. DSC data also showed an steady increment of Tg from 0 to 62 oC with increase in tannic acid weight % from 0 to 20 wt% respectively. Through this research, some better bio-based alternatives with extensive properties and work sustainably
