1. Polymer Material Stabilizers

Used as light stabilizers or UV absorbers, added to polymer materials such as plastics and coatings to prevent degradation, yellowing, embrittlement, and loss of mechanical properties caused by UV radiation.

2. Plastics Industry

Widely used to improve the outdoor durability and service life of plastic products such as polyvinyl chloride (PVC), polyesters (e.g., unsaturated polyesters), and polyolefins.

Suitable for plastic products that require long-term exposure to sunlight, such as outdoor furniture, building materials, and automotive parts.

3. Paints and Coatings

Used to protect the color and gloss of coatings (such as automotive paints, industrial coatings, and wood coatings), preventing chalking, loss of gloss, and cracking due to UV radiation.

4. Professional and Industrial Products

Used in applications requiring high transparency and UV resistance, such as eyeglass lenses, car window tinting films, and protective layers for optical devices.

Effectively blocks harmful UV rays while maintaining high light transmittance.

5. Scientific Research

Used as a chemical standard or reference substance for analytical testing, method development, instrument calibration, and environmental monitoring research. In scientific research, it is also used as an organic synthesis intermediate to prepare more complex heterocyclic compounds.
