AI Overview
UV Stabilizer 123 (HALS 123) is a low-alkalescency, liquid Hindered Amine Light Stabilizer (CAS 129757-67-1) designed for coatings, paints, sealants, and adhesives. It protects against UV-induced degradation—such as cracking, gloss loss, and yellowing—making it ideal for automotive, industrial, and wood coatings.
Key Characteristics and Applications
- Performance: Highly effective in acid-catalyzed, high-temperature curing systems.
- Applications: Ideal for automotive clear coats, polyurethanes (PU), acrylic resins, sealants, adhesives, and rubber.
Often utilized to replace BASF Tinuvin 123, this additive enhances the service life of coatings exposed to harsh weathering.

What are UV light stabilizers additives?
UV additives, which are also known as UV absorbers and stabilizers, are chemically formulated to absorb the high energy of ultraviolet light and protect the plastic product from exposure to this energy. With UV additives, the plastic products do not come in contact with most of the UV light's harmful radiation.

What blocks 100% of UV rays?
UV Coating: Critical for blocking 100% of UVA and UVB rays, essential for ultimate eye protection. This coating is separate from the lens material but is standard on all UV400 sunglasses. Anti-Reflective (AR) Coating: Minimizes lens reflections, reducing glare for clearer vision in bright environments.

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.
