UV Absorber 292 Performance Benchmark & Technical Datasheet
This technical datasheet establishes the performance benchmark for Bis-pentamethyl-piperidyl-sebacate (CAS: 41556-26-7), manufactured to industrial grade standards by NINGBO INNO PHARMCHEM CO.,LTD.. Designed as a high-efficiency liquid HALS, this Light Stabilizer 292 delivers superior UV protection for automotive and industrial coatings. Our rigorous QC ensures every batch meets strict GC/HPLC validation criteria, providing a reliable drop-in replacement for legacy formulations requiring consistent viscosity and amine value.
Deep Chemical Synthesis Route and Mechanism Discussion
The synthesis involves the esterification of sebacic acid with 2,2,6,6-tetramethyl-4-piperidinol under catalytic conditions. The resulting Bis-pentamethyl-piperidyl-sebacate functions through the Denisov Cycle, regenerating nitroxyl radicals to scavenge alkyl radicals. This mechanism prevents polymer chain scission, ensuring long-term gloss retention. For formulators seeking detailed integration strategies, our Hals 292 Formulation Guide Industrial Grade Coatings provides essential compatibility data with polyurethane and acrylic binders.
