Used as a reactive radical scavenger and stabilizer in polymer systems, particularly in coatings, adhesives, and plastics. Its free radical nature allows it to effectively inhibit degradation caused by UV exposure and oxidative stress, enhancing the durability and lifespan of materials. Commonly applied in high-performance polymers where long-term stability is critical. Also utilized in specialty resins to prevent discoloration and mechanical failure during weathering. Can be incorporated into crosslinking networks due to the epoxy functionality, providing permanent fixation within the matrix and sustained protective effects.
