Casting resins are clear, viscous substances generally made of reactive prepolymers that cure with the application of certain catalysts or hardeners. Among the most recognized varieties are phenolic, epoxy, and urethane resins. These materials are extensively utilized in the electronics sector, protective surface coatings, and the conservation of wooden furniture owing to their superior mechanical strength, chemical resistance, and longevity. Traditionally, casting resins originate from petroleum-based sources, which poses problems about environmental sustainability, carbon emissions, and the depletion of non-renewable resources. In reaction to these challenges, researchers have progressively focused on bio-based solutions. Renewable raw materials derived from flora, fauna, or microbes demonstrate potential in substituting traditional petrochemical feedstocks. Plant oils are particularly plentiful, biodegradable, and structurally conducive to chemical modification into high-performance polymers. Soybean oil is one of the most thoroughly researched feedstocks, with global output estimated at around 59.18 million metric tons from 2022 to 2023. Epoxidized soybean oil (ESO), a chemically altered derivative of soybean oil, has become a prominent choice for the formulation of bio-based casting resins. This work investigated the conditions for the epoxidation of ESO and its subsequent interactions with various reagents. The findings indicated that ESO-based resins can provide durable, load-bearing materials appropriate for sophisticated applications.
