Materials exposed to sunlight and artificial light sources are constantly under threat from ultraviolet (UV) radiation. This radiation can initiate photochemical reactions that degrade polymers, coatings, and other organic substances, leading to a loss of performance and aesthetic qualities. To counter these effects, the chemical industry utilizes a range of protective additives, primarily UV stabilizers and UV absorbers. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical manufacturer and supplier, sheds light on the science behind these essential additives and the critical role they play in modern material science, particularly featuring our advanced UV-329.

The fundamental principle behind UV stabilization involves preventing or slowing down the degradation process caused by UV light. There are two main categories of additives that achieve this: UV absorbers and Hindered Amine Light Stabilizers (HALS). UV absorbers, such as our UV-329, function by absorbing UV radiation and converting it into harmless thermal energy. They act as sacrificial agents, effectively shielding the material from the damaging wavelengths. HALS, on the other hand, work through a different mechanism, scavenging free radicals that are formed during the degradation process, thus interrupting the chain reaction. Often, a combination of UV absorbers and HALS provides the most comprehensive and long-lasting protection.

Our UV-329, a high-purity (97% Min.) benzotriazole derivative, is a prime example of an effective UV absorber. Its molecular structure allows it to efficiently absorb UV light across a significant portion of the spectrum, making it highly versatile for various applications. In the plastics industry, it is incorporated into formulations for products like automotive components, outdoor signage, and packaging films to prevent yellowing, brittleness, and surface degradation. For the coatings sector, UV-329 is crucial for maintaining color fidelity and preventing gloss reduction in paints and varnishes exposed to sunlight. Its anti-aging properties also contribute to the longevity of elastomers and adhesives.
