Used as a stabilizer in polymer systems, particularly in polyurethanes and plastics, to prevent degradation caused by heat and UV exposure. It functions as an antioxidant and hydrolysis stabilizer, enhancing the durability and lifespan of materials exposed to harsh environmental conditions. Commonly applied in coatings, adhesives, and elastomers where long-term performance is critical. Also utilized in industrial lubricants and sealants to maintain viscosity and chemical integrity over time.
