Used as a reactive flame retardant in high-performance polymers such as epoxies, polyurethanes, and polycarbonates. It functions by integrating into the polymer matrix through covalent bonding, providing permanent flame resistance without leaching. Its aromatic amine groups enable crosslinking, enhancing thermal stability and mechanical strength. Commonly applied in electronics, aerospace components, and fire-resistant coatings where durability and safety are critical. Also serves as a curing agent and char promoter, improving the material’s performance under high-temperature conditions.
