1. Acts UV326 CAS 3896-11-5 as a high-efficiency UV absorber in polyolefin & PVC processing, preventing polymer degradation, discoloration and brittleness under long-term outdoor sunlight exposure.

2. Serves UV Absorber 326 as a light stabilizer in coating formulations, enhancing weather resistance and gloss retention of architectural, automotive and industrial protective coatings effectively.

3. Functions as a UV protection additive in agricultural film production, extending service life of polyethylene films and maintaining crop protection performance stably.

Store UV326 (CAS 3896-11-5, light yellow crystalline powder, odorless, mp 137-142℃, non-flammable, purity ≥99%) at 10–25℃ in sealed amber glass/HDPE containers in a cool, dry, dark and well-ventilated area. Isolate from strong oxidants, acids and moisture to avoid oxidation and agglomeration. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local UV absorber & polymer additive environmental regulations.

UV326 is a polymer UV absorber, not for direct pure-form human contact or ingestion; undiluted contact may cause slight skin dryness, and accidental intake will lead to gastrointestinal discomfort. In regulated applications, UV Absorber 326 features efficient UV absorption (270-380nm), excellent thermal stability and low volatility, has good compatibility with various polymers, and exhibits remarkable synergistic effects with antioxidants/HALS for long-lasting protection.
