Coating industries are well expanded across the globe to provide a better coating. The increased usage of petroleum products to cover up their demands creates many issues. In this research, we have used limonene, a biobased chemical, for fabricating high-performance coatings. Thiol-ene click chemistry was used to introduce hydroxyl functionality into limonene. Limonene-polyol was methacrylate with methacrylic anhydride through an esterification reaction to proceed further for UV curing formulation. According to FT-IR analysis that hydroxyl functional groups held by the structure of limonene were transfigured into the corresponding methacrylate. The methacrylated limonene-polyol was prepared for UV curing via the addition of a photoinitiator and a different amount of cross-linker, where this mixture was applied to a steel surface and cured under UV light to provide a cross-linked structure, which gives strong surface adhesion and scratch-resistant coating. The coated material is also characterized by FT-IR, TGA, Tensile, and in various environmental conditions. This research presents a bio-based convenient synthesis procedure with a lower cost for coating applications.
