The sun's ultraviolet (UV) radiation is a pervasive environmental factor that can significantly degrade a wide range of materials, particularly polymers and coatings. Understanding the science behind UV degradation is the first step towards implementing effective protection strategies. As a leading supplier of protective additives, we offer UV Absorber 928, a crucial component in mitigating these detrimental effects.

UV degradation occurs when photons from UV light strike polymer chains, imparting energy that can break chemical bonds. This process, known as photodegradation, can lead to several undesirable outcomes: embrittlement, color change (fading or yellowing), loss of gloss, surface cracking, and a general deterioration of mechanical properties. The rate and severity of this degradation depend on factors such as the polymer type, the intensity and wavelength of the UV exposure, and the presence of other environmental stressors like heat and moisture.

UV absorbers, such as our UV Absorber 928, are specifically designed to combat this photodegradation. They function by absorbing UV light within a specific wavelength range and then dissipating this energy as harmless heat through a rapid, reversible photochemical process. This sacrificial absorption effectively shields the polymer matrix from the damaging UV photons. UV Absorber 928, belonging to the hydroxyphenyl benzotriazole class, is particularly effective due to its strong absorption in the UV-A and UV-B regions and its excellent photostability.

The benefits of incorporating UV Absorber 928 into formulations are substantial. Its high thermal and environmental permanence ensures its effectiveness even under demanding processing conditions and throughout the material's service life. Coupled with excellent solubility, it integrates seamlessly into coatings, plastics, and other sensitive materials. For applications like automotive clear coats, protective industrial coatings, and even certain consumer goods, this additive significantly extends product lifespan and maintains aesthetic appeal. Typical use levels range from 1% to 3%, providing a cost-effective means to enhance product durability.
