Used as a crosslinking agent in high-performance polymers, particularly in the synthesis of thioether-based networks for aerospace and electronic materials. Its dual thiol functionality enables efficient step-growth polymerization with epoxides or maleimides, yielding thermosets with excellent thermal stability and mechanical strength. Commonly applied in advanced composites, encapsulants, and as a curing agent in specialty resins where resistance to thermal degradation is critical. Also explored in the development of photo-patternable materials due to its reactivity in radical-mediated processes.
