Hindered-amine light stabilizers are a class of sterically hindered organic amine compounds, all based on the important 'azacyclic' intermediate triacetone amine derivative. The technical level of such 'azacyclic intermediates' directly affects the technical level of the final hindered-amine light stabilizers and is one of the core key technologies in HALS production processes.

Tiangang is one of the few domestic enterprises that synthesize light stabilizers starting from source monomers. This award-winning project is the result of Tiangang and Tianjin University leveraging their industry–university–research advantages in a series of key technologies such as 'preparation of azacyclic fine-chemical intermediates,' combined with the enterprise's own production-process characteristics, achieving a successful technological breakthrough and industrializing a preparation technology representing internationally advanced levels. The new technology not only improves the conversion rate of HALS intermediates and reduces by-product impurities, but also enhances the effectiveness and anti-ageing efficiency of subsequent light-stabilizer products, and features environmental, safe and stable characteristics.

As polymer materials are increasingly widely used in all areas of human society, the consumption of hindered-amine light stabilizers is also growing year by year. The economic benefits brought by the innovation and industrial application of intermediate-preparation technology will also benefit many downstream polymer, coatings and other high-molecular-material enterprises.
