Used primarily as a light stabilizer in polymers, this chemical protects materials from degradation caused by UV radiation. It is especially effective in polyolefins, polyurethanes, and acrylics, helping to prevent yellowing, cracking, and loss of mechanical strength during prolonged outdoor exposure. Common applications include automotive parts, coatings, textiles, and agricultural films where long-term weatherability is essential. Its hindered amine structure allows it to function as a radical scavenger, interrupting the chain reactions that lead to photodegradation. Often combined with other stabilizers for enhanced performance, it provides durable protection without significantly affecting the clarity or color of the final product.
