Abstract: In the present study, castor oil has been modified with blending of phenolic resin and phthalic anhydride to synthesize polyol. Then these modified polyol are reacted with toluene diisocyanate (TDI) in presence of a suitable catalyst to synthesize the PU coatings. The copolymer structure was confirmed by Fourier transform infrared spectroscopy (FTIR); whereas thermal characteristics of the materials were characterized using dynamic mechanical analysis (DMA) and its ultraviolet resistivity is confirmed with the help of Ultra violet (UV-VIS) spectroscopy. XRD helps in determining the nature of PU. The gel time, hard time, mixing time and chemical or water resistance characteristics were also examined to confirm the performance properties.
