Epoxy soybean oil (ESO) is a renewable and eco-friendly raw material that offers a range of benefits, including low cost, non-toxicity, thermal and light stability, as well as good solvent resistance. It is widely used in various industries such as PVC plasticizers, food packaging, and pharmaceuticals. As the paint industry moves toward more sustainable practices—focusing on resource conservation, energy efficiency, and pollution reduction—epoxy soybean oil has gained significant attention due to its unique properties. Recent developments in cationic light-curing systems and epoxy soybean oil acrylate coatings have shown promising potential, expanding its application scope across multiple fields.
Soybean oil mainly consists of linoleic acid (51–57%), oleic acid (32–36%), palmitic acid (2.4–2.8%), and stearic acid (4.4–4.6%). Through epoxidation, which involves an epoxidizing agent and a catalyst, soybean oil can be transformed into emulsified or partially epoxidized forms. These modified oils contain both unsaturated double bonds and epoxy groups, with each molecule typically containing 3–4 epoxy groups. In the coating industry, ESO is often used in cationic photocuring systems because of its low viscosity and moderate polymerization rate, making it ideal for fast and efficient curing processes.
In addition to UV-free radical curing systems, researchers have also explored cationic curing methods involving ESO. One key advantage of cationic curing is that it is not inhibited by oxygen, allowing for rapid and complete polymerization even in air. Furthermore, cationic coatings exhibit a "dark reaction," enhancing their solvent resistance over time. Epoxy soybean oil acrylates, produced through esterification between acrylic acid and ESO, are gaining popularity due to their excellent performance and cost-effectiveness. The synthesis process typically uses catalysts like dimethylaniline, triethylamine, or other common initiators.
The long molecular chain and low cross-linking density of Epoxy soybean oil acrylates contribute to improved flexibility and adhesion in coatings. Given the relatively low cost of ESO, these acrylate-based photosensitive coatings offer great potential for commercial development. Companies like UCB in the U.S. have already started producing products such as Ebecry 860, highlighting the growing interest in this area.
Beyond traditional applications, ESO is being integrated into other coating systems as a modifier, enhancing performance while reducing production costs. Research into derivatives of ESO, such as soy oil phosphate polyhydroxy compounds, has opened new avenues for developing high-performance, low-cost, and environmentally friendly coatings. These innovations are particularly valuable for commercial use, as they support sustainable manufacturing without compromising quality.
In recent years, the application of ESO has expanded significantly. For example, cationic epoxy varnishes made from ESO are now used as top coats for beer cans, offering excellent adhesion, toughness, and resistance to high-temperature sterilization. Additionally, Epoxy soya acrylate coatings are suitable for metallized films, paperboard varnishes, wood finishes, and pigments. As the paint industry continues to shift toward greener and more energy-efficient solutions, the future of epoxy soybean oil in coatings looks increasingly promising.
