Cationic, thermally cured coatings using epoxidized soybean oil

Soybean oil-based UV-curable coatings strengthened by crosslink agent derived from itaconic acid together with 2-hydroxyethyl methacrylate phosphate

“…[4,5] Especially, its derivatives epoxidized soybean oil (ESO) and acrylated epoxidized soybean oil (AESO) have been widely applied in the UV curable coatings. [6,7] However, due to the flexible long aliphatic chain of soybean oil, as much as 50% or more petroleum-based rigid compounds, such as styrene [8,9], acrylate acid [10] and divinylbenzene [11,12], are necessary to make its mechanical or thermal properties acceptable for end use. Recently, with the rapid progress on bio-based materials, the exploration of bio-based compounds to strengthen the polymers derived from soybean oil so as to ensure a higher bio-based content has been frequently reported [5,[13][14][15][16][17].…”

Vegetable oil-derived epoxy monomers and polymer blends: A comparative study with review

“…Poorer thermal and mechanical properties result from both partially unreacted ESO and saturated fatty acid (FA) chains that reduce reactivity and self-plasticize. Most ESO industrial uses are thus limited to nonstructural, additive applications such as plasticizers or stabilizers for poly (vinyl chloride) [13], oil-base coatings [14] with low strength requirements [15]. Though the mechanical strength of cured ESO can be improved with the addition of nano-reinforcements [16], or fiber reinforcement [17], an inherently low T g inevitably limits practical applications because T g for a polymer must be appropriately higher than the temperature of its intended work environment to serve as a useful plastic [18].…”
