  "abstract": "Epoxy thermosets typically exhibit a fundamental trade-off between curing speed and thermomechanical performance: thiol-cured systems enable rapid gelation but often produce low glass-transition temperature (Tg) networks, whereas amine-cured systems provide high Tg materials at the expense of slow curing kinetics. Here, we report a high-functionality, non-ester polythiol and a cooperative thiol-amine curing strategy that overcomes this limitation. Systematic variation of catalyst loading, epoxy stoichiometry, thiol-amine composition, and amine structure revealed strong structure-property relationships governing cure kinetics, thermal behavior, and adhesive performance. For the pure thiol-epoxy system, increasing catalyst concentration significantly accelerated gelation to minute-scale curing, while epoxy excess enhanced increased Tg without altering gel time. Hybrid thiol-amine formulations achieved substantially higher Tg than thiol-only systems while maintaining rapid cure, and the introduction of a primary amine largely eliminated the need for an external tertiary amine catalyst. Furthermore, the cooperative curing strategy proved effective across structurally different amine curing agents while maintaining rapid curing and balanced thermomechanical properties. This cooperative curing approach provides a simple and versatile platform for rapidly curable epoxy thermosets with balanced thermal and mechanical performance.",
