Abstract

This paper reports the preparation of polyurethane (PU) coatings using aromatic diisocyanates (methylene diisocyanate (MDI), toluene diisocyanate (TDI), and MDI/TDI mixture) with natural diols like curcumin, employing an organotin catalyst (DBTDL). The PU mixtures were applied using a brush on steel, aluminum panels, and various polymers, and their coating characteristics were evaluated, including gloss, scratch resistance, impact resistance, pencil hardness, and chemical resistance. Increasing the molar ratio of natural diols enhanced coating flexibility but reduced hardness. Additionally, the PU coatings were analysed for thermal stability using thermo gravimetric analysis, demonstrating the successful production of eco-friendly, bio based PUs through an economically viable process
