For professionals in the plastics, coatings, and adhesives industries, selecting the right additives is crucial for product performance and longevity. Among the most vital additives are UV absorbers, which protect materials from the detrimental effects of ultraviolet radiation. This guide aims to assist formulators in making informed decisions, with a particular focus on the benefits of 2,4-Dihydroxybenzophenone as supplied by us, a leading chemical manufacturer and supplier in China.

Understanding UV Degradation

Ultraviolet radiation, especially from sunlight, possesses sufficient energy to break chemical bonds within polymers. This process, known as photodegradation, can manifest as yellowing, chalking, loss of gloss, embrittlement, and a significant reduction in mechanical strength. Effectively mitigating these effects requires the incorporation of UV protection agents.

Benzophenone UV Absorbers: A Key Category

Benzophenone derivatives are a well-established class of UV absorbers, prized for their broad absorption spectrum and efficacy. Among them, 2,4-Dihydroxybenzophenone (CAS No. 131-56-6) stands out. Its chemical structure allows it to efficiently absorb UV radiation in the UVB and UVA regions (280-320 nm), making it a cornerstone additive for many applications.
