A study of the film properties of pigmented UV‐curable epoxidised soybean oil

Development of new radiation‐curable materials for the application in radiation curing technology is of significant importance. Most of the commercially available radiation‐curable resins are derived from synthetic raw materials. The synthesis of acrylated, epoxidised soybean oil (ESO) from ESO had been carried out by reacting acrylic acid with the oxirane group in ESO. The acrylated ESO products were characterised using a variety of analytical techniques. Thus, the oxygen value, the iodine value, the acid value and the infrared spectra of the acrylated ESO products were obtained. Pigmented acrylated ESO systems were prepared and found to cure on exposure to UV radiation.
