Soy-Based Building Blocks for Advanced Photocure Coating Systems

Abstract

Phone: +1 734-487-1235.Photocuring technology is among the fastest-growing advanced coating technologies primarily due to their sustainability features, potential for enabling new products, and economy. 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.

Green Polymer Chemistry: Some Recent Developments and Examples

“…Mannari et al (46) developed soybean oil-based building blocks and demonstrated their suitability as alternative raw materials in advanced UV-curing coating compositions. An example was a hyper-branched soy urethane acrylate (HSPU), used as the primary component of a UV-curable composition.…”

Furanic (Meth)acrylate Monomers as Sustainable Reactive Diluents for Stereolithography

“…Although multiple different types of biobased RDs were offered for thermally curable thermoset compositions, , the development of sustainable diluents for UV-curable resins remains focused mainly on (meth)­acrylate chemistry. Plant oils and oil-derived fatty acids remain the principal source of raw materialsbiobased acrylates and methacrylates were synthesized from soybean oil, tung oil, castor oil, ricinoleic acid, and cardanol. , Sugar-derived acrylates synthesized from sucrose and tetrahydrofurfuryl alcohol and isosorbide , were also used as RDs in UV-curable thermosets.…”

Bio-Based Furanic Di(meth)acrylates as Reactive Diluents for UV Curable Coatings: Synthesis and Coating Evaluation

“…Currently, commercial reactive diluents are typically derived from petroleum-based products, which has caused sustainability concerns and stimulates the development of bio-based raw materials . Bio-based materials are often looked upon as inexpensive, nontoxic, abundantly available, and renewable raw materials for UV curing applications. ,,− A number of research studies have been carried out on modification and application of bio-based materials as resins or reactive diluents for UV curing, such as soybean oil-based acrylates, castor oil-based diacrylates or triacrylates, , cardanol-based acrylates, , and tung oil-based methacrylates …”
