The search for environmentally friendly and —greener" materials in the polymer field is further explored to decrease dependency toward petroleum-based products. Sucrose soyate, a complex molecule of sucrose and fatty acids of soybean oils, provide an alternative renewable material for petroleum-based coating resins in addition to the already existing choice of drying oils. In this research, the unsaturation of sucrose soyate was modified into acrylate functionality by means of epoxidation and acrylation – these functional groups provide sites for the crosslinking polymerization through ultraviolet irradiation. Mechanical and thermal properties of the coating formulations with different degrees of acrylation and various reactive diluents were evaluated. All of the coatings produced were found to have a high crosslink density which leads to excellent chemical resistance, high glass transition temperatures and good hardness of the coatings.
