Changes in physical properties, chemical structure, and color of the samples were monitored by mechanical property testing, FTIR spectroscopy, and colorimetry, respectively. A stable polyurethane coating was achieved at 0.5% concentration of additive in the host matrix. Mechanical properties were also retained as in the pristine PUR after mixing. Commercial Tinuvin P and benzotriazole-based novel UV absorbers were found to improve the photoresistance of the PUR coating, and the highest efficiency of the novel UV absorber against weathering was estimated at 0.5 wt% concentration.(c) 2005 Society of Plastics Engineers.</p>1 aKumar, A., P.1 aReddy, K., R.1 aRana, S.1 aLonkar, Sunil, P.1 aRaut, K., G.1 aSingh, R., P.  uhttps://library.ncl.res.in/content/synthesis-characterization-and-performance-evaluation-novel-stabilized-tdi-based-0
