Novel bio-based thermosets

This technology introduces a fully bio-based thermosetting platform built around highly functional epoxy resins derived from vegetable-oil polyol esters and crosslinked using multifunctional carboxylic acids. The resulting coatings, films, adhesives, and composite matrices deliver strong mechanical properties, excellent adhesion, and good thermal stability while being free of organic solvents and volatile compounds. Importantly, the cured networks are engineered to degrade under alkaline or thermal conditions, unlocking a new dimension of recyclability for thermosets. With water- or low-alcohol-assisted curing, the system offers a greener processing route for industries seeking high-performance materials aligned with sustainability and circular-economy demands.

Benefits

• 100% bio-based composition derived from renewable vegetable-oil feedstocks
• Strong mechanical performance with excellent adhesion and thermal stability
• Solvent-free and low-VOC formulation for safer, greener manufacturing
• Controlled degradability enables recyclability and circular material recovery
• Versatile curing options, including water-assisted or low-temperature processes
• Comparable strength and durability to petroleum-based thermosets
• Reduced environmental footprint and compliance with sustainability standards
• Broad compatibility with coatings, adhesives, and composite manufacturing systems

Applications

• Protective and industrial coatings for metals, concrete, and composites requiring strong adhesion and durability
• Adhesives and sealants for automotive, aerospace, and construction applications
• Composite matrices for lightweight structural materials in transportation and infrastructure
• Eco-friendly resins for wood coatings, flooring, and furniture finishes
• Encapsulation materials for electronics and renewable energy systems
• Recyclable thermoset components for sustainable manufacturing and circular economy initiatives
• Biodegradable films and coatings for packaging and agricultural uses
