1. Plastics Industry:

Used in various plastics such as polyvinyl chloride, polystyrene, polyolefins, epoxy resins, cellulose resins, and unsaturated polyesters to prevent degradation and aging caused by ultraviolet radiation from sunlight or fluorescent light, maintaining stable appearance and mechanical properties.

2. Coatings Industry:

Added to various coatings, such as automotive coatings, architectural coatings, and industrial anticorrosive coatings, to improve the weather resistance of the coating, extend its service life, and prevent problems such as discoloration, chalking, and cracking.

3. Rubber Products:

Applied to synthetic rubber products, such as rubber seals, rubber pipes, and rubber conveyor belts, to enhance the rubber’s resistance to UV aging, slow down the aging process, and ensure its performance and service life.

4. Textile Field:

Used in textile finishing to provide UV protection for fabrics and other textile materials, preventing discoloration, embrittlement, and decreased strength under sunlight, especially suitable for outdoor textiles such as sunshades and tent fabrics.

5. Acrylic Glass Protection:

Can be used in the production or post-treatment of acrylic glass products to reduce UV damage to acrylic glass, preventing yellowing and brittleness, and extending the service life of acrylic glass products.

6. Chemical Synthesis Intermediate:

A key intermediate for the synthesis of other benzophenone-type UV absorbers, such as 2-hydroxy-4-methoxybenzophenone (UV-9) and 2-hydroxy-4-n-octyloxybenzophenone (UV-531), which are commonly used UV absorbers.

7. Daily Chemical Products:

Used in small quantities in some daily chemical products to protect the active ingredients from decomposition under light, such as in some skincare and hair care products, where it acts as an auxiliary stabilizer for the formula.
