Despite these benefits, the materials used in the current photocure systems are predominantly derived from petrochemical sources, making them unsustainable over the long term. Development of renewable resource-based alternate materials tailored for photocure applications is, therefore, critical to future sustainable development of photocure coating technology.This presentation highlights our research efforts in developing a platform of soybean oil-based value-added building blocks and demonstration of their suitability as alternative raw materials in advanced UV-curing coating compositions. A hyper-branched soy urethane acrylate (HSPU) has been developed and used as the primary component of UV-curable composition. Coatings based on HSPU with varying acrylate content (using reactive diluent) and high bio-based content have been characterized and compared. Due to hyperbranched structure and large free volume in their inherent structure, they exhibited interesting properties for many potential industrial applications. Another group of soy-based derivatives-low viscosity and high-functionality acrylate monomers-have been designed and used as reactive diluent in UV-cure formulation. The study demonstrates potential of these low odor and bio-based reactive diluents as partial or full replacement of conventional reactive diluents.
