Abstract: The 3M Digital Materials Hub is a newly developed data platform that accelerates material selection and simulation by providing validated, simulation-ready material data cards. This study demonstrates the integration of predictive curing and viscosity models for a thermoset epoxy adhesive film (AF 503), representing an advanced implementation of digital material data beyond conventional property databases. Differential scanning calorimetry (DSC) experiments at multiple heating rates (1–10 K/min) were analyzed using a two-step kinetic modeling approach based on the Kamal–Sourour and Nth-order reaction models. The resulting kinetic parameters enable prediction of degree of cure under variable thermal cycles. Model predictions accurately reproduced dynamic and isothermal curing behavior (R² = 0.97) and demonstrated complete conversion above 140 °C within 120 minutes. By embedding such verified kinetic data into the Digital Materials Hub, this work extends the platform beyond static property data, enabling process simulation, reducing manufacturing risk, and enhancing digital material design workflows across diverse engineering applications.
