Coatings and adhesives are essential in numerous industries, providing protective layers and bonding capabilities. However, their exposure to environmental factors, especially ultraviolet (UV) radiation, can lead to degradation, compromising their performance. NINGBO INNO PHARMCHEM CO.,LTD. offers Hindered Amine Light Stabilizer 622 (HALS 622) as a vital additive to ensure the durability and aesthetic integrity of these critical materials.

UV radiation can cause significant damage to coatings, leading to phenomena like chalking, cracking, gloss reduction, and color change. For adhesives, UV exposure can weaken the bond strength and affect the overall integrity of the assembly. This is where HALS 622, a high molecular weight polymeric hindered amine light stabilizer, proves invaluable. It functions by scavenging free radicals generated by UV exposure, thereby preventing the chemical breakdown of the coating or adhesive binder.

The unique properties of HALS 622, including its low volatility and resistance to migration, are particularly beneficial in coating and adhesive formulations. Low volatility ensures that the stabilizer remains effective during the curing process of coatings and the application of adhesives, which can sometimes involve elevated temperatures. Its migration resistance means that the protective agent stays where it's needed, on the surface or within the bulk of the material, providing sustained protection against weathering and UV damage.

By incorporating HALS 622, manufacturers can extend the lifespan and maintain the visual appeal and functional performance of their coated products and bonded assemblies. This additive works synergistically with UV absorbers and antioxidants, creating a comprehensive protection system. The result is enhanced durability, ensuring that the coatings and adhesives can withstand the rigors of their intended environments, whether indoors or outdoors.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-performance solutions for the coatings and adhesives industries. Hindered Amine Light Stabilizer 622 represents our dedication to developing advanced chemical additives that deliver superior protection and value.
