Used as a crosslinking agent in dental resins to improve mechanical strength and durability of restorative materials. Enhances polymer network formation, contributing to better wear resistance and reduced shrinkage during curing. Also applied in adhesive formulations where high bond strength and chemical resistance are required. Its disulfide bond allows for potential reversible network behavior, useful in self-healing polymer systems. Commonly found in light-curable dental composites and orthodontic cements.
