AI Overview
UV Stabilizer 123 (CAS 129757-67-1) is a low-alkalinity, liquid hindered amine light stabilizer (HALS) based on amino-ether technology, widely used in high-solids, acid-catalyzed, and automotive coatings. It prevents degradation, chalking, and cracking, offering excellent compatibility and performance in coatings, inks, and adhesives.
Key Features and Benefits
- Low Basicity: Its low alkalinity makes it ideal for acidic systems, interacting less with acid catalysts and preventing discoloration or curing issues.
- High Performance: Provides superior protection against gloss loss and cracking.
- Compatibility: Excellent compatibility with various resin systems, including polyurethanes (PU), acrylics, and UV-curable coatings.
- Synergy: Strong synergistic effect when combined with UV absorbers (e.g., UV 1130, UV 384) to maximize weather resistance.
- Appearance: Typically a light-yellowish viscous liquid.

What is UV stabilizer used for?
The UV Absorbers / Stabilizers listed are used to absorb UV light. This protects paints, plastics, coatings, adhesives, etc. and thus stabilizes them to UV light or natural sunlight. UV radiation is one of the major causes of degradation of textile materials, and therefore benzotriazoles can be found in some textiles.
