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

Abstract

Development of new radiation-curable materials for the application in radiation curing technology is of significant importance. Most of the commercially available radiationcurable 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.

Coatings derived from novel, soybean oil-based polymers produced using carbocationic polymerization

“…3 Similar to other liquid multifunctional acrylates, acrylate-functional plant oils have been used in radiation-curable coatings. 18,19 In addition to serving as a starting material for the generation of acrylate-functional plant oils, epoxidized plant oils have been used to generate plant oil-based polyols by reaction of the epoxide groups with, for example, methanol. 20 These polyols can be formulated with isocyanates to produce polyurethane coatings.…”

Synthesis and performance of a thermosetting resin: Acrylated epoxidized soybean oil curing with a rosin‐based acrylamide

“…With characteristics of little irritation and a low viscosity, epoxidized soybean oil is widely used in the areas of plasticizers, food packaging materials, pharmaceutical products, and so on . The further derived acrylated epoxidized soybean oil (AESO; see Figure ), which contains reactive vinyl groups, has been applied in the areas of coatings, packaging materials, paints, and adhesives . Although it has other advantages, such as a low toxicity and inherent biodegradability, the inferior glass‐transition temperature ( T g ), mechanical properties, and weak rigidity of AESO limits its application prospects in structural applications because of its aliphatic structure …”
