Description
Cristiane da Silva Fonseca and four colleagues cure epoxidized linseed oil, a plant-based epoxy stand-in, with two hardeners and map how each network forms. One hardener was an anhydride, the other a fatty amine. The amine reaction starts more easily on paper, with lower energy barriers. Time-temperature-transformation diagrams charted each system's race between curing and vitrification, the moment the growing network freezes into glass and slows its own chemistry.
The anhydride network ended dense and stiff, with a high glass transition, near-complete gel content, and the stronger, harder solid. The amine network stayed flexible and stretchier, tore later, and even tolerated higher heat before breaking down. The authors show that freezing and diffusion, not raw reactivity, govern which system wins on speed. Their maps give makers of sustainable resins a practical guide for picking a hardener and processing window to match the job.
