In this study, acrylated epoxidized soybean oil (AESO) has been successfully synthesized from epoxidized soybean oil and acrylic acid. Subsequently, AESO was modified using a biobased long chain diacid (Pripol-1009) with the assistance of a water/ethanol blend to form waterborne epoxy acrylate (WBEA). The properties of the cured WBEA with 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane as initiator were studied through spectral analysis, coating properties evaluation, corrosion resistance, and morphological and thermal analysis. The results revealed that WBEA exhibited relatively better mechanical, thermal and corrosion resistance characteristics over cured waterborne epoxy.

The reaction parameters involved in the synthesis of WBE from ESO have been optimized based on physicochemical properties like hydroxyl value, epoxy equivalent value and degree of solubility of WBE. The WBE obtained after 5 and 6 h of reaction time was found to be of optimum composition with balanced physicochemical properties. The mechanical, thermal and physicochemical properties of WBE obtained after 6 h of reaction time revealed relatively better performance characteristics as compared to ESO.
