The integrity and longevity of coatings are significantly impacted by environmental factors, chief among them being ultraviolet (UV) radiation. For applications involving high-temperature curing, such as powder coatings and coil coatings, selecting a UV absorber that can withstand these conditions while providing robust protection is essential. Our UV Absorber 928, a leading hydroxyphenyl benzotriazole, is specifically designed to meet these rigorous demands.

UV Absorber 928 excels in high-performance coating applications due to its unique combination of properties. Its core function is to absorb harmful UV radiation, preventing the photochemical degradation that leads to color fading, chalking, and a reduction in gloss and mechanical strength. What distinguishes UV Absorber 928 is its remarkable thermal and environmental permanence. This means that even when subjected to the elevated temperatures often encountered during powder coating curing cycles or coil coating processes, the absorber remains stable and effective.

For coating formulators, this stability translates into reliable and consistent UV protection over the product's lifespan. Many conventional UV absorbers can degrade or volatilize at high temperatures, diminishing their protective capabilities. UV Absorber 928, however, maintains its structural integrity, ensuring that the coating remains shielded from UV damage. Its excellent solubility also aids in achieving uniform dispersion within the coating matrix, crucial for achieving consistent performance across the coated surface.

The recommended use of UV Absorber 928 in these applications typically ranges from 1% to 3%, offering a potent defense against UV-induced degradation at a cost-effective concentration. Furthermore, it can be effectively paired with Hindered Amine Light Stabilizers (HALS) to provide a synergistic protective effect, further enhancing long-term weatherability and durability. This makes it an invaluable additive for exterior automotive parts, architectural panels, appliance finishes, and other demanding applications.
