Hindered amine light stabilizers (HALS) are chemical compounds that contain amine functional group in their chemical structure, which are used as stabilizers. HALS are polymer coatings used in dyes and paints. These compounds are derivatives of 2,2,6,6-tetramethylpiperidine. Hindered amine light stabilizers are effective stabilizers against polymers, degradation of which induced by lights. These compounds do not absorb UV radiation, but are effective for the inhibition of polymer degradation. These compounds slow the degradation process which is initiated by photochemical process. The working mechanism of HALS is almost similar to antioxidants compounds. These are highly effective for light stabilization of polyolefin (such as TPE, PE, PP, and TPO), polyamides, styrene polymers, polyurethanes, adhesives, polyacetals, and sealants. Hindered amine light stabilizers contribute to the thermal oxidative stability of polymers, especially polyolefin. It functions by ending photo-oxidat...
