Light stabilizer 292, mixture of bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate and methyl 1,2,2,6,6-pentamethyl-4-piperidyl sebacate (CAS 41556-26-7)

Light stabilizer 292 is a compound extensively used in polymer chemistry research for its ability to protect polymers from degradation caused by ultraviolet (UV) radiation. The mixture incorporates both bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate and methyl 1,2,2,6,6-pentamethyl-4-piperidyl sebacate, which act as hindered amine light stabilizers (HALS). Research involving Light stabilizer 292 typically examines its effectiveness in prolonging the life of plastics and coatings by scavenging free radicals formed during photo-oxidation. This stabilizer is also studied for its compatibility with various polymers and its ability to maintain transparency and mechanical properties of materials exposed to sunlight. Additionally, investigations into the synergistic effects of Light stabilizer 292 with other additives, such as UV absorbers and antioxidants, are for developing advanced materials with superior resistance to photodegradation. The compound′s role in enhancing the durability of outdoor applications makes it a subject of interest in materials science and industrial research.
